Sorry I took so long to get back to you, too many hobbies...

I got the rear mount from livefastmotors, put it on the bike in Fall of 2007

At this point wouldn't recommend it for reasons:

1. Needed to epoxy clutch drive cylinder to threads of tire roller, as it kept spinning off the roller when going down hills, locking up against the engine (!) - don't remember if I described this above.

2. Looks like the tire roller metal "teeth" are wearing out really fast. We have put maybe 300 miles on the bike and I don't think it should be wearing out so fast. I need to get a new roller at some point, and will need to get a clutch disk having epoxied it to the threads. Not sure at this point if I am even going to be able to get the tire roller out of the mount, having the disk epoxied on.

I have ridden this bike on some dirt roads, and on cinder (old railroad beds) wondering if this material is wearing off the teeth somehow. Anyone got experience with this ?

You should also look at Island Hoppers for rear mounts. Reasonable price, and I think they have been in business for awhile.
