An update on my Windsor Cyclo after about 2000 miles with which I commute with on 60-80% trails, rest road, about 32 mi RT, 500 mi/mo. Tacoed my stock front wheel trying to do an old mountain stunt in an emergency - duh. So I replaced the stock 32 spoke wheels with Mavic Aksium 20 spoke. Finding myself needing to true these Aksium since the flooding weather here has created deep ruts in the trails against which I have bashed repeatedly. Still I like these Aksium wheels and don't mind investing in a good truing stand.
The stock Shimano 105 rear shifter quit working accurately so I replaced them with Utegra 6700. Probably overkill on this bike, but I got a really good price on them, I like the wider and more solid hoods, the internal routing, and they shift great. Also the stock KMS chain stretched after around 1000 miles so I replaced it with an Ultegra chain.
I got nervous about the generic stem after a report it cracked in half on another Windsor Cyclo so replaced it with a good deal on an Easton EA70 OS stem from Jensonbike.
Also replaced my old clipless pedals wit Shimano M540 and that crunching noise went away
Only complaints I have about the rig is the frame and forged cranks are a little flexy, but not enough to bother me - in fact it is a good ride on the trail with the CF fork (hope that doesn't fail!)
Cheers
