I want!

Buells have been gay since the came out and so is that

yeah nah

A thousand USD's? at that rate it would be 10 years before it is a sensible price.

And then only for SS or gearbox bikes. There is no mention of friction either.

Match that with a rolhofffffff and you got a noise free ride.

Need a split/two piece stay. And a cover if your off roading. Dirt would cut it up, though I do notice holes right through the sprockets.

Bridgestone bikes have been there and done that 20yrs ago. Belt drive is good cocept for single speed type stuff but they were ahead of there time when 1st came out, very quiet and by far stronger than a chain.

Where is there going to be friction in a solid belt?

All the normal places: at the contact point with the cogs, and within the belt itself as it flexes.

so. Trek now... cool. i liked the Spot ones when i saw them... apparently they're SILENT

Lots more friction bending a belt than pivoting an oiled chain I would have thought.

I do like the noiseless aspect, but I also like the range of gears for my out in the middle of nowhere epics... and the fact that I can fix a chain if it breaks (although I would think it would be harder to break a belt).

Think about all those links rotating, way more friction!

Harley and Buell have been using drive belts for years and you never hear about them breaking

More contact area = less friction I would've thought, plus no rollers in the chain to rotate and wear!

I think that Jericho was the SS company that had proto-types of a bike just like that for years.

Looking at the link, looks like taking the cog off and retro fitting an internally geared hub should be quite do-able.


A low maintenance/no oil needed chain system will be a goer for the likes of rental/fleet bikes.
