Emergency Frankenbike Question(5 posts)

I mangled the rear derailer on my cyclocross bike. I don't have the money to replace it this close to Christmas. I have a spare XTR rear derailer and a race this weekend. My question is will this setup work:

Chorus 10sp Shift/Brake levers + Chorus 10sp Cassette + XTR Rear derailer = working drivetrain?

It seems at first glance that since the derailer works by the cable pulling against the spring that as long as the shifters and cassette match, everything should be fine. It can't be that simple.

I recently found this interesting tutorial on making half-breed conversions. If you scroll down to the 2nd or 3rd page you can see the method for rerouting the cable on your shimano mountain derailluer.

Actually, come to think of it, if you have a campy cassette then you probably won't have any trouble at all.

Good luck

Shimano RD have a different throw ratio than Campy.

but bolt it up and try. might not shift well but maybe enough to race on. other cheap options: pick a cog you like, cut the chain and make a single speed. or try to borrow a friction bar-con or D/T shifter (if you have D/T boss on frame). that will shift any combo.

I'd try it. Try adjusting your cable tension so that a cog in the middle is spot on. That way any slop will be divided between the two extreams.
