Mixing road and mtb components?(4 posts)

Mixing road and mtb components?Star Fangled Nut

Is it possible to use XTR front and rear derailleurs with say, Ultegra or Dura-Ace STI shiftlevers? If so, anything I need to know about chainring/cassette size? Also, does anyone know if an 8-speed rear derailleur can be used as a 9-speed derailleur? I have an old XTR 8-speed short cage derailleur (same cage length as Dura-Ace) and would be using it with a Dura-Ace cassette with no more than 25 teeth on the biggest cog. Thanks again for you help!

Yes you can mix. I run Ultegra levers w/ an XTR drive train 46-34 Crank and 12-27 Ultegra cassette. Works like a dream. An 8 speed derailleur I don't think can work as a nine but a 9 can work as an eight. Handling a 25 tooth cog will be no problem. You probably will need a 9 speed rear derailleur, maybe someone can shed some light more.

The only problem I see with using the 8sp XTR is that the pulleys might not work well with a 9sp chain; if you're really set on using this derailleur, check and see if it would be worth (cost-wise) replacing the pulleys with the 11-tooth 9sp versions. Otherwise, it should be fine. The travel across 8sp and 9sp cassettes is the same.

The only issue I ran into with Ultegra shifters and XT front and rear derailleurs is that the lever arm of my bottom pull XT front derailleur would rub against my Michelin Mud tires in the big ring... A quick swap to an Ultegra FD cured the problem.
