Auto news on Youtube Apr 9 2018

- A few months back, we pitted a bike

that we found on Ebay for 100 pounds

against this super bike, a Canyon Aeroad,

with Shimano's top of the range Dura-Ace 9170 groupset.

And the results were pretty stark.

This one was significantly faster.

But what was really surprising was the margin of victory.

I mean, this was on another level.

And so it got us thinking, just how much money

would you need to spend in order to actually shut that gap?

And to be fair, many of you wondered exactly the same thing

in the comments section under that previous video.

So we have come back to our horrible climb

and our torturous descent and our flat time trial.

But with this, a Canyon Endurace AL 7.0.

Now, it retails for just over €1000,

or just under £1000,

making it a purchase for a committed bike rider,

but very much still in the mid-range category.

It's got a lightweight aluminum frame.

It's got Shimano's ever-reliable

workhorse groupset, the 105.

And it's also got a very sprightly

set of Mavic wheels on there.

But just how much faster will this super bike still be?

I tell you what, I'm going to need

some help for this, actually.

I can't do it on my own.

Matt?

Matt!

Matt!

- [Matt] We're going to test these,

firstly on our horrible climb.

It's not exactly an Alp, but it's plenty hard enough.

Although just two kilometers long,

the average gradient is 11%,

and there's a really big chunk at 22%.

- On a climb like this, the major difference in speed

between these bikes is going to come down to the weight.

Now this super bike, if you remember, is no featherweight.

Its major strengths lie elsewhere.

But that aside, it's still pretty

remarkably light at 7.3 kilos.

- Now remember, our cheap bike

weighed in at 11.95 kilograms.

For this mid-range bike also, let's weigh her in.

- 8.9, so that's a pretty bonkers

3 kilos weight saving between

our bargain basement and our mid-range.

Although clearly, to save more weight

is going to cost quite a lot more money.

In this case, what's that,

like 1500 grams costing five grand.

- So, Si, let's put our money where our mouths are.

- Yeah, how much faster does 1500 grams get you?

- Getting a bit nervous. - Yeah, I am, actually.

- I know, it's a tough climb, isn't it?

- It is, I remember how much it hurt last time.

Right. - You focused?

- Yeah, I think I am, actually.

- Right then. - Okay.

- I'm going to count you in. - Alright.

- Alright.

(imitating beeping)

(energetic music)

(imitating beeping)

Didn't get me foot in.

Almost disaster at the start, but here we go.

- Run number one and I'm riding the Aeroad

and Matt is on the Endurace.

We are going to ride this climb flat out.

And on paper, you might expect to see the Aeroad

have a margin of victory of about six seconds,

because of the weight saving.

But the Endurace may just have a trump card,

because the 105 gears that are specced on there are compact,

so that could allow us to ride the steepest section

at a more comfortable cadence, a more optimal cadence.

Now, we specced the Aero, meanwhile,

with standard race-oriented gears,

although it does take advantage still

of the new Dura-Ace's ability

to use a 30-tooth cassette at the back.

But nevertheless, the smallest gear

on the Aeroad is still bigger.

(upbeat music)

(heavy breathing)

Hey, Matt.

How'd that feel, mate?

- Pretty brutal, but not too bad,

considering it was my first ride for quite a long time.

It felt really light.

Gear selection, although not quite as smooth as Di2.

Functional, no issues with the gears, nice low gear ratio.

And I actually managed to stay seated

for the vast majority of the climb,

which is saying something, since we're talking about that.

Do you know what, it felt pretty good.

What about you?

- Well, I can't complain, if I'm honest.

It's everything you'd hope, isn't in?

- I was going to say, yeah.

- Well, I have to say, the chain's a bit dirty.

- [Matt] Not much to--

- [Si] But you need to scrub it off a bit.

- Not much topping that, it's better than your shades.

Okay, run number two.

I get to go on that one.

(imitating beeping)

- Go on, go on. - That was quick.

That's not seconds. - First time, you're in.

Go on, three is enough.

- Tell you what, first impressions, very positive.

(imitating beeping)

- He's in!

Here we go.

Run number two and a quick bike swap.

So that we haven't altered the bike spec at all,

we're using PowerTap P1 pedals to monitor power output,

as well as just going full gas.

Another difference between the two

is that while the Dura-Ace of the super bike

has a power meter option, 105 doesn't.

As we mentioned, the Endurace is really light,

particularly for the price.

The frame is about 1390 grams,

which is only about 300 grams more than the Aeroad.

(energetic music)

- Whose idea was it to do max effort?

(heavy breathing)

Terrible idea.

(heavy breathing)

There he is.

Super.

Right, well, leaving aside the fun factor for the ride--

- It was fun? - Yeah.

What of the results, Matt?

Let's get straight in there.

- [Matt] Well, 10 seconds quicker on this bike, but--

- [Si] 10 seconds.

- But for pretty much the same power.

So not much, isn't it?

- No, well, to be fair, this one,

this one, I, was even closer.

Eight seconds faster on the Aeroad.

- [Matt] Eight seconds, that's not much at all though.

- [Si] No, it's not.

- [Matt] Wow.

- I mean, to a certain extent, we can't be too surprised,

because a climb that steep doesn't really

play to the advantages of our particular super bike.

And the weight difference of 1.5 kilos,

that's not the be-all and end-all, is it?

That's probably what's made the difference,

a shade of 10 seconds or eight seconds.

And you know, the other thing

that the can come into play, really, are the gears.

But actually the difference in performance, really,

between Endurace and 105 is quite slight, isn't it?

- It is, well, the first thing to mention,

of course, is that 105 is a bit heavier.

So that's-- - Fair enough.

- So that's one of the contributing factors

for this bike being heavier.

But from a performance perspective,

there's not much separating them at all.

There's 22 gears.

They've got a similar array of ramps and pins.

Now, the main difference in relation

to separating the price points

is the materials used and also

the manufacturing process as well.

- The only other thing that I noticed,

and I don't think it affected the performance,

just perhaps the fun factor slightly, was just the position.

It's just a little bit more cramped on the mid-range bike.

But I could've sorted that out

with a swap of the stem, which wouldn't cost much.

Drop it 10 mil, get an extra 20 mil longer stem,

and that would've meant that I probably

felt a lot more comfortable.

But that's just what I'm used to, I guess, as well.

- Yeah, I mean, I felt exactly the same thing.

And remember I said I spent most of the time sat down?

I must've been, when I got out

of the saddle on the mid-range bike,

it didn't feel quite as comfortable.

But it felt pretty efficient, sat down.

Whereas on this one, I was out of the saddle a lot more.

It just felt far more efficient.

But again, same power but 10 seconds quicker.

So not much at all to call it, mate.

- Right then, mate, challenge number two is calling.

- Break time. - No, braking time.

Yeah, sorry, not break time.

On to challenge number two, braking.

Last time the might of the disc brakes

versus old, flexy rim brakes,

paired with some slightly ropy wheels, was no contest.

In fact, the stopping distance was almost doubled.

- [Matt] What though, when you have a good set of wheels

with a machined braking surface

and a really solid set of rim brakes?

- The test is a simple one.

We ride at 40 kilometers per hour,

and then when we hit this line, we jam the brakes on.

Just how long does it take these bikes to slow down?

Run number one is going to be

this Canyon Endurace mid-range bike.

And on it, we've got Shimano 105 rim brakes.

The caliper itself is made out of aluminum,

meaning that it is light and it's also stiff.

And that's the really important part,

'cause it means that the braking force

exerted by your fingers is transferred through the cable

and then directly into the pads,

and therefore onto the rim, slowing you down.

With a flexier caliper, although your power

does still eventually get to the rim,

the flex in the caliper means

that you don't have quite as much control

or as much feel over what is happening with the brakes.

The other factor that should help this bike

slow down quickly is the wheels.

So we've got Mavic Aksiums on here,

that again, made out of aluminum.

They've got a CNC machined brake track.

And that means it's almost a perfect surface

for those brake pads to grab onto.

(energetic music)

Run number two, disc brakes.

Now, not much can be said about disc brakes

that has not been said before.

Inside the brake line we've got hydraulic fluid,

as opposed to a steel cable.

So that improves the responsiveness of them even further.

And while those Mavic rims are very nicely machined indeed,

so too are our disc rotors.

And whereas with the rim brakes we've just got

rubber pads being squished against them,

the pads inside the disc brake

are much, much harder non-rubber compound.

So again, that improves the responsiveness.

And while we might not need

all the power that these brakes offer,

what we will take advantage of is the extra modulation

that allows us to use that power more effectively.

(energetic music)

Well, almost identical.

Has that taken us by surprise?

Not particularly, actually, it has to be said,

because we know that the brakes

on the mid-range bike are fantastic.

And actually, disc brakes only really

come into their own in the wet.

And thank goodness today is not wet,

because unlike disc brakes,

GCN presenters do not tend to come into our own in the wet.

Now, there is also a slightly funny

thing here we've got to mention,

in that a mid-range bike is almost always

going to come with aluminum rims on there,

which tend to offer better

braking performance than carbon ones.

Not always, some carbon rims are on a par with aluminum.

But there could've been a situation here where,

were our super bike to have had rim brakes,

it may actually have performed worse

in this test than our mid-range bike.

That said, a Dura-Ace rim brake caliper

would offer better modulation than a 105 one.

And particularly, if you're able to

go for the direct mount option,

which means that it bolts onto your frame

via two bolts instead of one.

That stiffens it up even further.

- Right then, so far, so good.

The difference between the mid-range bike

and super bike is pretty small.

But will the tables turn, now the speed's about to go up?

Test number three, it's the descent.

Unlike the cheap bike before, there's not going to be

too much of an advantage with braking here.

But we've yet to mention the trump card of the super bike.

And like its name suggests, the Aeroad,

well, it's aerodynamic.

- Not all super bikes are going to have that strength,

but then, we chose this one precisely because it does.

The Shimano C40 wheels should save a chunk of time.

So the deeper rim on there means that it causes

less turbulence as it passes through the air.

And that's helped by the wider profile,

and what's called its toroidal shape.

Now, because it's made out of carbon fiber,

it's still super-lightweight.

Were it to be made out of aluminum, like those rims,

then it would probably weigh a ton.

Now, you can, of course, stick those wheels into any bike.

But harder to swap are the aerodynamic

handlebar and stem on here.

But then even more intrinsic to the Aeroad

are the very shapes of the tubes that make up the frame.

And they are designed to cut through the air.

(cheering)

(energetic music)

Well, just like last time,

it is tough to truly put two bikes

through their paces downhill on an open road

without an unduly high risk of serious injury or death.

But nevertheless, once again the Aeroad steals a victory.

Why, well, we can only guess.

But the aforementioned aerodynamics

will likely be playing a role,

and the increased modulation of the discs

also instilled a greater feeling of confidence in us,

meaning that we were able to brake later and harder.

It's challenge number four, and it's crunch time.

You remember this?

It's the time trial.

Completely flat course, out and back.

And I suspect that just as when we put

our bargain bucket bike against a super bike,

this one is going to totally crush it.

Because aerodynamics are even

more important than people think.

And that bike is aero, and this one is not.

- And I get to go on this one first.

- You do make it look aero, mate.

- It does, look at that.

It's just built for speed, isn't it?

- Depends who's riding it.

No, actually, it doesn't.

It's built for speed, no matter who's riding it.

- Thanks mate, yeah.

(imitating beeping)

- [Si] You should've held me up, actually.

- Go on, Si.

(energetic music)

(imitating beeping)

(energetic music)

- Around 300, kept it.

8:39 was the time.

God, bit rusty there, mate.

Felt fast. - Yeah.

- Was so fast, what of yours?

- It felt really good, actually.

It's got to be said, it's a world away from that cheap bike.

Like it feels fast, like a proper road bike.

But I just have a feeling it's just going to be,

just not quite as quick as that one.

- No, I mean, this, like I said, it's really comfy.

The only thing that's wrong with it

is the engine at the moment.

But no, it certainly felt as quick

as I could push it, anyway, mate.

- Quick change and then-- - Round two, yeah.

Give it another nudge.

Super bike time for you, okay.

Three, two, one.

(imitating beeping)

(energetic music)

Well, I'm glad that's over.

- [Si] Yeah, so we got to find somewhere

for a coffee and a piece of cake,

get through these results.

- [Matt] Perfecto.

- You know what, Matt.

I'm not entirely sure what to think here.

That mid-range bike clearly represents

such great performance for the price.

It's kind of leaving me wondering

exactly what it is about a super bike that's so super.

- Well, one's thing for certain, Si.

It's good news, because after our

cheap bike V super bike test,

we were just left a little bit concerned

at the cavernous gap in performance.

And it's actually reassuring to know

that cycling isn't the preserve of the super-rich.

And maybe we're not as elitist

as a lot of people previously thought.

- Yeah, that is right, isn't it, actually?

Because while there's nothing stopping

the rider of our mega-cheap eBay bike from having fun,

the bike was seemingly stopping us from riding fast.

Whereas in this case, that mid-range bike

is super good fun and it is pretty darn fast as well.

I mean, the frame is what, 400 grams heavier.

The groupset behaves flawlessly.

And even when we try and put it to the sword,

aerodynamically, it wasn't that far behind.

- [Matt] It's a lot of extra money

for relatively minor performance gains.

Yet just the feel of it is far more engaging.

It's more agile, it's more responsive.

It's like it's willing you on.

- At this point, I suspect that you

are going to be split on this.

For many of you, this is just a sign

that you do indeed get minimal return

for your extra investment when you buy a super bike.

It is, of course, predominantly about the rider.

And actually, you probably think

that Matt's previous statement is just a bit fluffy.

Sorry, Matt, it's true.

But then for many of you,

you're going to agree wholeheartedly with Matt.

And that, yes, you can't actually explain

the difference between these two bikes with stopwatch alone.

Can you quantify just what makes

that super bike so rewarding to ride?

- Well clearly, Si, there has to be

something tangible that distinguishes super bikes,

because many people are lucky enough to own them.

And if that wasn't the case, they wouldn't.

Now, us as cyclists, it's a fact,

have become far more attuned

at noticing very small differences.

So drop your tire pressure, for example,

by 20 PSI, and you'll know about it.

Drop your saddle height by two mil

and it's going to drive you insane.

So as long as there's going to be

a measurable difference, you'll know about it.

So whether it's downhill, whether it's on a climb,

whether it's braking, or whether it's on the flat.

It's no surprise that we can still perceive that.

- Yeah, that is true, actually,

isn't it, when you think about it.

'Cause if you extrapolate out our short tests,

in percentage terms, on the climb, it was 2%.

On the TT, it was 4%.

So over an hour's ride, that would then be what,

two and a half minutes, roughly?

And so on a two hour ride, that's five minutes.

Quick maths there.

And you would definitely notice if you got to the cafe

five minutes earlier, wouldn't you?

- [Matt] So would your mates as well.

- That's a good point, actually.

And not only that, you'd also have to

buy another coffee, wouldn't you?

But I still can't get away from the fact that

that Endurace gives you so much bike for the money.

I mean, in terms of groupset alone,

when the bikes that we were racing on not 10 years ago,

the Dura-Ace, I don't think was as good as this 105.

I mean, it was 10-speed, this is 11-speed.

The shifters were a lot bulkier.

Like, that's just amazing.

That costs a grand and you could race on it brilliantly.

- I mean, there's no doubt the difference

between that eBay bike and the mid-range bike is vast.

And we should also throw in another

slight curveball when buying a super bike.

Although it performs better in every regard,

spending that bit more money

also allows you to tailor the bike.

Now, 7.2 kilograms is pretty light.

You could buy one for five kilograms and climb faster.

- Yeah, you could.

Or actually, you swap out the wheels

on that one for deeper ones,

and you could go even faster

on the flats and on descents as well.

So having more money does allow you more choice, doesn't it?

- But that still leaves plenty of room

to go further and find value in a super bike.

Yeah, the differences aren't that big,

but they're still significant and measurable.

And that doesn't even take into account

the kind of unquantifiable side of things as well.

- Yeah, I mean, like we said,

you get to the cafe five minutes earlier.

That's measurable and significant, isn't it?

- Definitely.

- Measurable in terms of time and also finances,

'cause you got to fund that extra flat white.

- And probably caffeine dehydration on top of that as well.

- Yeah, complex topic.

Now, I would imagine that this

is going to stir up quite a bit of debate.

So if you are not in the comments section already,

please head down there and let us know

what you think on this subject.

Do you feel that there isn't enough of a difference

between a mid-range bike and super bike

to justify that extra expense,

or do you feel that you can easily justify

a super bike if you can afford one?

Make sure you let us know.

- Yeah, now, if you want just a little bit more

of a detailed look at this very subject,

why not watch our geek edition

over on the tech channel to find out?

- Yeah.

HOW TO: IMPACT the FUTURE or Make a DIFFERENCE in the WORLD! 🌎 - Duration: 9:19.

Hey FI CREW!

This is Kaitlyn from Futuristic Inspirations!

How are you today?

Thanks for discovering my video!

You're now part of the FI CREW!

Congrats!

FI stands for Futuristic Inspirations!

Please watch until the end of the video, thank you!

This video is all about how to impact the future or make a difference in the World!

Quickly, Futuristic Inspirations is all about making a Positive Impact, Inspiring Others,

Sharing Ideas, and Cultivating Mindset.

We are the ultimate channel for: Science, Philosophy, Travel, and Education.

OK.

One question that I've always thought about is what I could do to help others, be of service

to others, and inspire others.

When thinking about how I would like to make a difference in the world, I start thinking

about all the different ways that I could make an impact.

I've created this video for all of you in hopes that together we can co-construct a

beautiful world to co-exist in now and in the future.

The more we delve into the topics of purpose, the meaning of life, and the current state

of the universe, then we can start to discuss, connect, and help bring about change that

otherwise may have not manifested.

The power of us together, each and every single one of us, is what could truly refuel and

reignite the world for a better existence here on earth.

Now I'm going to share with you some of the best ways to impact the future or make

a difference in the world!

Be sure to hit subscribe and press the bell for notifications.

Be a part of this awesome growing community!

Ok here we go…

The first way to make an impact on the future: Care about nature!

Nature is incredible, and nature is Earth's gift to us.

We are not automatically entitled to all of Earth's gifts.

We need to nurture them, give and not only take from nature.

That's the only way to truly be in touch with nature - when nature isn't a totally

separate environment from you.

You are effected by nature, and nature is effected by you.

We are living a cycle, and we, as active conscious humans, need to take more responsibility for

our contribution to the current state of the world, and start infusing nature with us,

and us with nature.

Start caring about nature, start realizing that nature is needed, and without nature,

so much opportunity and potential can be stripped away from us and future generations.

So, we need to actively conserve and preserve, and perhaps even innovate nature as we know

it, before it's too late, because really, there is a limit on the threshold that nature

can withstand.

And now, we need to come together, across nations, and find better solutions to protect

the ONE land we call home.

Let's take care of our land.

Who's with me?

Let's find better solutions, better policies, make nature and our land one of our main priorities,

in a way that we simply were not doing before.

Next, I am going to talk about wellness!

Wellness is another way to make an impact on the future!

In a very direct way, the way that we treat our wellness and the wellness of others, is

a big indicator of your potential impact on the world.

When you are healthy, feeling vibrant, alive, whole, and happy, you are in a much better

vibrational state to make a difference.

When you have a high vibrational frequency, and radiate wellness, you can tune into the

law of attraction with much more efficiency because you are a magnet for your thoughts

in the universe.

So make health your priority!

Because when you are feeling good, you will feel motivated and more likely to action on

your dreams and your passions.

NOW, to make an impact on the future or make a difference in the World, it's important

to focus in on your deep-rooted values and recognize what you are passionate about and

what your ultimate vision, goal, aim, or result is for what your trying to manifest and for

your life as a whole.

There is much development and innovation that humanity could accomplish in many important

industries and sectors.

You could contribute to the development and innovation in the areas of education, science,

technology, medicine, recreation, tourism, economy, agriculture, transportation, business,

communications, government, aerospace, the list could go on.

I hope you could see that there are various possibilities and opportunities out there

in the world right now, that you could start planning right now how you would best like

to impact the future or make a difference in the World.

Start today, start with small steps but lots of action, and be ambitious and honestly,

don't listen to the haters.

There are always going to be people who don't see eye to eye with you on the path or destination

that you are traveling, BUT don't let that stop you, because trust me when I say that

it's the people who persist in pursuit of their vision and dreams despite any circumstance

or opposing force that are going to have the opportunities to make a profound impact.

Go for it!

Don't wait!

Start making an impact today!

You never know what kind of amazing possibilities and opportunities that might manifest from

your dream of making a difference in the world.

Let's take care of innovation and moving the world into a space of more happiness,

peace, and compassion for all.

Lastly, I want to talk about how promoting peace and kindness is an amazing way to impact

the future or make a difference!

The more we look inwards, to find ourselves or our spirituality, we start to see the world

in a new way, you see...

We are the universe.

Therefore, as we learn more about ourselves and the universe, it becomes clear that we

are all interconnected, we are all one.

Community, being of service to others, helping others, adding true value, letting go of ego

and separation, are all essential to have impact or make a difference.

Let's take care of our spirit and others!
