Trek district

how long before we can belt drive a fixed wheel?

No guesses where the styling cues come from.

now, they just have to put it on nice bikes

Ha! That ^ is fugly.

cant see that working brakeless

and what about the chain? and the system to get tension? the dropouts are vertical, I don't know, i am not convince

...dropouts maybe vertical, but look at the two parallel horizontal 'adjustable' jobbies......quite complicated, how many ££££ I wonder?!. No greasy oily stuff though. I'm intrigued. Will be very impressed when it is turned into a fixed drive....which it undoubtedly will be sooner or later.

£500.

$930 converted and rounded up.

there isnt a chain, thats the point :P

Trek, failing where the Strida has failed before.

stop trying to re-engineer the bike, it works fine as is, thanks, bye.

"Farticle"
ha ha

Which is why you have an arrospok as your avatar.

its a BMX wheel

belt drive is one of the few technologies left that could benefit the long standing unchanged bicycle design.

I see this old fella on a old school (but very smart looking) touring bike frequently who has belt drive and it seems to work very well for him.

And most scooters, and a few motorbikes including the whole of BUELL's range are belt drive.

The belts are pretty high tech, made of kevlar and such. Cant see why it wouldnt be excellent on a pedal-cycle. Would weigh much less, and be maintenence free. It would be as much of a revolution as the transition between steel and aluminium rims.

how will it work with derailleur gears? how would one tension it? belts are a lot more expensive then chains, and give less signs of wear before they snap, and it wouldn't work on a track bike.

The first thing you do on a Harley or Buell when modifying it is bin the belt drive for a chain. You loose too much power in the drive train, and it stretches easily so requires constant adjustment for optimum performance, although they will work well enough even if slack. Their have been numerous Buell recalls due to belt drive issues.

Chain still rules

The lack of maintenance is the main benefit of belt drive, though they are way more expensive than a chain to replace. Shaft drive is much better from a practical point of view, though is heavier, and has a considerable amount of powerloss hrough the drivetrain.

how will it work with derailleur gears? how would one tension it? belts are a lot more expensive then chains, and give less signs of wear before they snap, and it wouldn't work on a track bike.

you would have to use a Rhollf (however you bloody spell it) kinda rear hub.

which kinda negates any weight savings you may have gotten.

oh well, least it wouldnt need oiling

our lift at work uses a chain. that's all i got. sorry

I'd see belt drive as quite cool for single-speed but can't quite see it working with fixed and any form of gearing would just be too much money or too impractical. Except [ame="http://en.wikipedia.org/wiki/Continuously_variable_transmission"]this[/ame].

how will it work with derailleur gears? how would one tension it? belts are a lot more expensive then chains, and give less signs of wear before they snap, and it wouldn't work on a track bike.

if they can engineer a less stretchy belt, then why wouldnt it be suitable for a track bike?

Obviously youd have one of the many alternatives to deraileur gears, hub or bb mounted gears innit.

Tensioning could be done the same way as it is now, you could have a sprung tensioner for freewheelers who dont like the hassle of fiddling with the perfect tension. And fixed wheel riders, could just HTFU.

Should be seeing some on the roads very soon.

Will be interesting to get some feedback on a single-speed belt-drive bike.

it wouldn't work on a track bike.
Why? Belt drive motorbikes generate forces on the belt that are far greater than a human being could generate, not even Chris Hoy could match that. For the commuter I think it could work. Maybe even for the track as well, but that remains to be seen.

I really want a fixie inc. one thought!!

in that case, how long (or how many mileage) does it take for it to be replaced?

That is a hypothetical only Tynan could answer. But I think he's having his afternoon hibernation. Shhhhhhhh.

Belt drive talked about here. With sort of an answer for you ed.

A reprasentative from the company chips in half way through the circlical discussion.
I'm kind of suprised to see so many cropping up so soon, but I guess the road bike offers less of a challenge.
