I would not worry about mud, it would just get squashed out haha. I just think the derailleur would be too big. Maybe not, if it was a skeletonized type, but... still, think of the width, and how much more you'd have to move it sideways, just to make it change "gears".

you can't make a belt change gears and it needs to have constant tension

hahah

Well, in THEORY, maybe if they used a very stiff spring in the derailleur, always pulling towards the back of the bike, so as it swaps "gears"... but it would never work, since it would missalign with the wheel and gears and then you'd have a sloppy/drooping belt....

So yea, you're right. I did know it always needs tension, like the fan or timing belt in a car, but I guess an internal hub derailleur would work.

'Chainline' is somewhat critical on SingleSpeeds...
BeltLine is WAY More Critical...
No Derailleurs with these belts, (Maybe future, more 'flexible' belts?)
Internal Gearbox Transmissions, or Hubs? Yes!!!
Dual Belt Ring and Dual Cog? Yes... Climb. Stop. Change. Go...

We here at *BELT Me and Drive Me Crazy* modify bikes with Sliding or Horizontal Dropouts, Eccentric BottomBrackets, and other potentially compatible designs and arrangements, to accommodate Belt Drives...
We also make custom bikes to YOUR Measurements or Specifications... Wild 'One-Off' Specials are also available...
What are your desires?

Try "NuVinci Bicycle CVT" for a variable hub drive w/ that belt...
and maybe a Hammerschmidt type planetary drive up front to get really crazy

Your car uses belts for many more miles than your bike would. The paddles shed mud. The whole thing is light and grease free

You cant use this on a double suspension, except if your pivot is on the BB

taletotell (Mar 14, 2012 at 5:19)

I don't see why you couldn't have a high tension belt derailleur on this.

doubledeuce (Mar 14, 2012 at 6:17)

I think it would get too bulky, unless you built it up as an internal rear hub derailleur... Maybe I am wrong?

I don't like internals. They are less efficient. A three speed belt cassette should work and 2 in the front equals good enough for most FR and DH

I do believe belt-drives are less efficient than a typical chain drive-system. And I can't see a rubber belt being more effective in muddy conditions.
