Can I use Campy triple crank with Shimano group?(9 posts)

Can I use Campy triple crank with Shimano group?kilimanjaro

Some details.

I am contenplating this because I already purchased the BB and Centaur triple crankset. I figure it is cheaper/easier to go this route rather than sell everything and start over. I plan to use Shimano Dura Ace 9spd downtube shifters which I beleive have friction mode for the front so that should not be an issue?

Any potential problems with such a setup?

This actually will not work for me because I want to use downtube shifters. Campy D/T shifters do not have a friction mode which defeats the purpose for me.

It is interesting that they have a 30 max cog in the back. I am pretty sure that Campy 9 speed RD only officially supports 29 max in the back.

With a Shimano type rear wheel and any Shimano rear changer, the downtube shifters will work in the friction and the index mode. Any Shimano 9 speed cassette will work.

I have Campy cranks and Shimano Derailleurs/Cassettes on 4 bikes and they work perfect together. Just be sure to get a front Der. for a triple crank. Only problem I noticed was on an early 90s Record crank w/original chainrings and the 9 speed chain would derail when shifting from large to small ring. Fixed it by getting some TA Campy 9/10 speed compatible rings and it shifts just fine now. I use Dura Ace downtube shifters, in index mode, on all 4.

If Campy DT rear shifter has a friction mode (which it does not), then I can have a friction mode backup that shifts any rear 700c wheel/cassette combination. This would nice on a long ride, specially with relatively low Campy market adaptation at leat in this country. Of course this may be a lot less of an issue as Shimano moves to 10 speed.

Do you get a lot of wheel changes on long rides?Kerry

Most of us just replace the tube if we get a flat. Or by long rides do you mean long races? It seems that your chances of needing a wheel change would be pretty slim, and you would pay a continuing penalty for having friction shifting instead of index. YMMV.

I think you misunderstood my post. Shimano DT shifters and bar end shifters have both index and friction mode. The friction mode is only for back up. Let's say you For this reason long distance tourer tend to use barend instead of STI.

It is also not just wheel change. Let's say your RD is out of wack. If you have friction mode you might still be able to shift. Or your RD is toast on a long tour. You can put on any derailleur and you will have some shifting capability.

We put a Campy Racing T triple 50-40-30 on my wife's bike. The shifters, derailleurs, and chain were Ultegra. It shifted as well as the original Ultegra triple, but maybe a bit noisier. These shifters were STI, I don't know why you want down-tube shifters. Indexing is not an issue with the crank-set.
