Belting!

What the fuck are you talking about? Of course you could move your wheel back.

Now breathe, I know that I didn't state this in my original post but I was referring to the bike in the picture and unless my eyes deceive me I can't see any dropouts so to speak.

Please re-read the post and note the general tone, thank you.

el squire - check the hub on the rear wheel, it's an eccentric hub, like this one below;

Does anyone know a UK manufacturer or stockist of belt drives? i.e. only the drive train, without a bike attached?

I might have a wee commission to design a plywood bike, and a non-greasy silent belt might be just the ticket...

I dont know of any. But then I'm not UK based either.

More info here maybe.

Well they said planes would never fly...

With some kind of bolt on rear drop-out, (drive-side) so the belt can be replaced /changed, no reason at all why not.

Weight saved on the chain, might be slightly offset by thicker chainwheel/rear sprocket depth.

Some kind of lip/retention will be required on the drive system to stop the belt sliding off.

I love the idea of a belt drive.

My rear drop out splits in two with the removal of a back plate.

The belt saves a lot of weight.

The sprocket is made from a melamine like plastic and saves a lot of weight.

The chainring is also made of the same plastic and saves a lot of weight.

The inside edge of the sprocket has an lip, and the outside edge of the chainring has a lip. With the correct tension these hold the belt on nicely.

me too but I fear they create as many issues as they solve. I'm not too concerned about the lack of adjustability in belt length, more the coupling/dropout issue, eccentric hubs etc.
Smallfurry's solution looks neat.

will wait a few years and see how it progresses, which system gets market share etc.

Gates pretty much has it cornered. Still, its difficult(findingparts) + expensive to build your own bike with it.

I think evolving tech. is fine though I would worry that someone may cut belt whilst bike unattended and as funny as it sounds I don't think a pair of tights would work....so does anyone know how much for a new belt/s?

It would take a lot to cut it. I've bounced mine off rocks and there isnt a mark on it!

I new one cost silly money (too lazy to google)
