I just bought a Hope Conversion kit from jensonusa.com and it got here in one day. It cost $30 american. I have a singlespeed on vertical dropouts with no tensioner....i just got lucky that the chain fits with perfect tension. Good luck with your bike.
the axel is 30 bucks. my brand new hope on a 721 cost me alot of money im not going to spend more and lose money when i could easily spent 30-40 and have some down time. i need theese chain tugs though. because i only have 3mm of stay clearance and no matter what i do it is necessary. i need one that contacts the axle inside of the drop out not on the outside(if that makes sense)
