Finally some review of classified hub:
It looks very promising to be honest, especially as a platform for future development.
Finally some review of classified hub:
I read that too, I like the idea of a race bike with massive range and aero front rings.
Would make things like the 3t viable for hilly/mountainous areas.
Where are you getting that info from? The linked article said Classified claim it’s as efficient as a regular 2x system. Though admittedly there’s no actual data or testing in the article to validate that claim so I’d want to see independent testing!
I want to know about the efficiency loss when the planetary gears are spinning. The current design on a bicycle drivetrain is one of the most efficient designed. But with planetary gear like in rear wheel drive vehicles there is efficiency loss. Same reason FWD cars are more efficient then RWD. These gears in the rear hub are always going to be spinning.
Lets not talk about how its a proprietary cassette and hub, thats more work then it might be worth. No interchanging wheels also this is the only bike with the design it might act up and you have a 1k paper weight. Also if there is a problem ridley dealers are pretty limited in the states. It sucks you cant run 650b wheels, and you cant run 2x. This might be the perfect bike if you could run 2x, as its as aero as the noah and takes 42c wheels. I saw someone in england put 43c on the frame
With that being said, I have one in a box minus the rear hub. I hope to compare to my N+1 bike the aspero. I am a massive Aspero homer also, this will be an interesting build and I have spared no expense to give it a fair comparison.
To be fair I think the only reason it takes 42c is because it doesn’t have a front mech…
I really like to look of this bike regardless of the classified hub - as long as the hub doesn’t suck more than 3-4w of my power in the easy gears I’ll go for that option I think.
The good thing is if you lose 5w with the hub, the bike makes up for it in aero gains. Of course we really have very limited aero data on gravel bikes. 3T, Kanzo Fast, Aspero should be thrown in a wind tunnel and get some data.
The bar on the kanzo is very nice. The flair on it is awesome. Crappy thing is that you can not run a longer stem and your stuck with ridleys bar, as the steerer tube is not a circle.
This is interesting. I’m assuming there’s no loss in 1:1, which is what’s important. Seems like it doesn’t add too much rear weight, which is a problem with the Shimano Alfine hubs. $1000 is rough.
Ride report is MANDATORY!
Will do, It might be the first one in the states, I have had an injury for a few weeks or I would have ridden it. I did not get the hub though. I found it to be too much risk I wanted reliability.
That is bloody lovely.
How does the bike feel weight wise? One problem with the Shimano Alinfe hub I had for a while is that bike always felt SUPER heavy in back when carrying or adjusting the position of the bike while stopped.
The bike feels great, I do not have the classified hub. I did not want it at this time. Limited wheel options, limited parts availability I have no ridley dealer with in 2 hours of me, limited testing on the product ( since when people have tested it for magazine it has failed). At this time my bike is a GRX 1x set up with a 44 front and 11/42 rear, I will swap a 50 front for flat races. I think the 11/42 is 430g and the 11/34 is 330g so I cant tell the difference by hand.
I’m lusting after a campagnolo Ekar build of the Kanzo Fast now. I think it’s probably a more sensible option instead of being a guinea pig for classified… and there is a chance I could actually afford it.
I sold my aero road bike for Ridley. I figured if I wanted more gear I could just put a 50 on and since the bottom 6 cogs on the cassette are the same as a 11/28 I wouldn’t really have any negatives except swapping rings and weight for cassette.
