Dura ace on a MTB

[singletrackmind]

I read that some of the top pros use a dura ace front derailer with a 29 tooth small ring, no granny ring,  will this work well and will it last as long as an XTR?

Can't imagine that front chainrings experience much wear and tear, even on a MTB - and they are simple, hard-wearing components.

 

 

 

The front derailler on my road bike is many years old and still going strong. But it is campy....

Y ?

I'm guessing because shimano doesn't make double-chainring front deraillers for MTB?

[kingjreid]

hahaha, some MTBers use a dura ace cassette and chain on flat-ish mtb races...

I read in the new Bisikling that Burry uses a Deore FD

[singletrackmind]

They dont make double for MTB. I see the 1 guy from canondale and sauser rode this setup the whole epic and didnt fail. But im just not convinced enough to go out and try this yet, need some advice please

[dirtrider]

It is actaully very,very easy to get a Deore or LX FD to behave like a twin blade derailure . But a FD is actaully a very simple part and like BB noticed , even the bottom of the range ones works perfectly . If a roadie derailure gonna fit on your bike then it will work . But y ?

I had a UK MTB magazine (can't remember which one and unfortunately have thrown it away) where a staff member set up a Giant hardtail with Campag road mech. Double chain ring and 10 speed cassette. He used the shifters from one of their touring groupsets. Had been running it for a year with zero problems. Nice one for a Campag fan to try out.

Iv converted my sram x9 to a double but its still not as good as my road derailer. So might just give this a go. Thanks for the input hubbers.

What crankset are you using, where are you getting a 29 tooth ring from. I ask because if you are using a hollowtech 2 crankset you will also have to take a spacer out, drvie side,  so that the 2nd ring sits closer to the frame, this will stop the chain from dropping as often. I also run an XTR crankset and would like to know where u are getting 29 tooth rings from? 

[dirtrider]

Try and find TA chainrings . According to Brown they the only ones to make 29 teeth

[singletrackmind]

FSA makes them aswell, but can only get them on CRC and a few other manufacturers make them aswell. But I use a 32 with a 34 on the rear. and im using a firex crank

[singletrackmind]

FSA make a proper compact MTB crankset, the k-force light

DR- do TA have an SA distributor?

[dirtrider]

Nothing I can find .
