It is interesting that all the bikes polished to their peak, do not have over size pulley wheels and 28 mm tubeless tires🤔 Maybe I, as the last Mohican with 25mm tires and tubes, am not wrong 😁
The video is very big on the branding, but much less on the specific advantages or rational behind the tech. So, lots of cool looking stuff, but is there any more to it than style?
I think a video is needed to explain the aerodynamic benefits of 3- and 4- spoke front wheels. They seem noticeably shallower than some of the traditional spoked wheels.
@@cosimorossi9712 I'm unsure how lighter as most rims from say 20mm or 25mm depth is 250g and go to say 50mm depth be like 330-400g Personally apart from large chainring I don't see wheel weight changing much
68 tooth I remember back when some guy ran an unheard of 58, back in like 2017 ish ... Although i do think he ran a normal cassette on the back for his tt's
1:10 - An interesting volta... The first Shimano road bike brake rotors (Ultegra and Dura Ace) used to have cooling fins of the size and shape of these carbon inserts.
They aren't if you have a good clutch and don't make your chain as long as possible. After all, few world cup mountain bikers use chain guides and you rarely ever see them drop chains
It‘s interesting to see different concepts of front wheels. Normal, tri-spoke and four spoke. I‘d love to hear a discussion with an expert. Does it depend on the fork which one is best?
A question for GCN or someone in the know, does Pinarello pronounce Bolide as the French "Bowl-leed" or more English "Bow-lied"? I hear the presenter say "Bow-lee-day" accenting the end with a the acute accented "é" though it's not present. Does Pinarello pronounce it differently to try to make it their own thing?
i really hope that someone starts to make cheaper versions of these. i don't even care if it's made from cheaper material i just want the aero benefits.
Colnago unceremoniously leant up against a picnic table? Cannondale and Factor precariously leaning on a building column at a jaunty angle? Van Rysel leant against a concrete wall and at a jaunty angle? Scott Plasma shot at a nearly head-on view? Look Monoblade leaning against a van in a freeking parking lot? Cube on a tree with the front wheel pointing south? Merida on a jaunty angle about to be run over by a van? BMC up against a wall scraping the Wattshop carbon aerobars? Sorry. Just "nice."
Here's Dura Ace cassette teeth numbers: 11-12-13-14-15-16-17-19-21-24-27-30 68 / 4 = 17. Same ratio on the smallest cog 11 x 4 = 44. Which cog preserves the most straight line for the chain? 11 or 17?
@arvishzadeh A better comparison would be with a 54t chainring. 54/11 is approx same as 68/14. so with a 68t ring the 14 and maybe the 13 sprockets are for riding a bloc on the flat. and as you imply, more efficient to be in the middle of the cassette, plus bigger sprockets are more efficient anyway regardless of chainline. 15 to 19t for more technical flat sections and slight inclines. 11 and 12 are now available for pushing hard down long descents, very useful for low negative gradients. 68/11 at cadence of 85 is approx 70kph. 19t would be about 40kph. Makes a lot of sense mechanically and strategically.
@@michawasiljew6620 that's definitely not true. Unless you consider Specialized to be a small brand because the Tarmac and Shiv are some of the lightest bikes on the market.
Important enough to save 20g per brake disc on a TT bike but not that much as to slap half a kilo or more when going from rim to disc brakes on climbing bikes, makes perfect sense.
Which is your favourite bit of tech in this video? Let us know 👇
The colnargo TT BIKE it is awesome
❤

Definitely the Sharpie tooth-count

Is that a rim brake giant TT bike?! May be the last rim brake bike in the world tour 😢
That Black Inc disc is gorgeous !!

Time for GCN does science?!
It is generally tested that 3-spoke are pretty much always slower than spoked wheels, except for velodrome when there is zero sidewind.
2:11 That chainring is so huge it's basically the diameter of mountain bike wheels from a few years ago 😂
I was waiting to see but disappointed 68t? I can buy a 75t chainring or unless that be too much for TT
Isn't it better ? In TT you don't need braking performance. .. rim is lighter and maybe also more aero

Will be interesting to see how Cian and Roglic get on in TT's after swapping teams and Cian being critical of Bora's TT setup.
I think he really just didn't like the bike above all else. It's most definitely fast so that's not really an issue.
@@veganpotterthevegan probably. Just like to cause a stir lol
Thick forks of Colnago and Pinarello looks so empowering. I’d like to see these designs in road bikes as well!

These bikes are looking like they’re from a different planet
🪐
Love TT bikes!😍
That Colnago is so good looking. I'm in love with the three spoke Princeton wheel tho from Ineos and their Pinarello.
I just put a 1X on my Aethos, I got a Sram aero chain ring 48 tooth "smallest" Sram makes.
Opening the video with that Colnago made everything else just B-role grade.
God I love time trialling, my favourite discipline by miles.
Rear mechs works best with their original pulley cage, no one stops to say "hang on,what do ceramicspeed know about precise shifting"
Didn't know those Chainguides were necessary, thought a narrow wide ring would do the trick
They aren't if you have a good clutch and don't make your chain as long as possible. After all, few world cup mountain bikers use chain guides and you rarely ever see them drop chains

Wow I had no idea Giant Trinity has Quick release axle
Rim brakes, mean there is no need for a thru-axle
That chainring is starting to compete with the great white shark for the most teeth.
🦈
Imagine having disc brakes on a tt bike 😂 pretty un-aerodynamic
0:26 That Black Inc disc wheel on the Factor Hanzo looks amazing. 😍
I would have liked to see more than 5 seconds of each bike. Maybe next time, OK?
Cheers
u can use pause button😂
Super video,the CNC Kronos 58t front chainring looks incredible,one of the best ive seen.Safe riding.Thankyou GCN crew.💯👌🏻✌🏻🚴♀️
4:07 "Bahrain Merida"? :p
Movistar-Banesto 🙃

Thought weight wasn't important, it should matter even less on TT bikes, lies lies.
Big brands struggle to compete with smaller companies by making lighter components so they gravitate towards aero.
Nobody said it's not important, just that it's significantly less important.

Weight still matters. just less. But when the sport is competitive you look to improve anywhere you can
0:47 And GCN used to say "aero is everything". The most stupid claim ever.
