Campagnolo rear derailleurs for MTB bikes(14 posts)

Campagnolo rear derailleurs for MTB bikeszacdos
Nov 1, 2003 8:29 PM
Hi I am a mountain biker who would like to try a Campy rear derailleur for my off road bike. My cassettes biggest cog is 32 teeth, however according to Campy no derailleur will work with that size of cog. I have had people tell me a long cage derailleur will do okay. Has anyone tried this and did it work. Thank you
Why would you want to do that?the bull

Even I use Shimano on my mtn bike!

?? I have never heard of a Campy on an MTB. There is a good chance that a Campy derailleur built for a road bike will fail miserably on a mountain bike. Even Shimano makes MTB-specific derailleurs.

If you are not a Shimano fan, go with SRAM. Their new '04 derailleurs are outstanding.

For you history buffs.. it was called Euclid.

That said, get a Shimamo or Sram rear derailleur. You are better off getting a part that was designed to do what you want it to do.

Anything in the Shimano line Deore and up is good.. and the Sram derailleurs are great as long as you use their shifters with them.

If you need more info than this, try asking on the mtbr.com discussion boards instead.

I think that was the top stuff.the bull

They even had a couple of lower lines.
It was nice stuff too!
I rember looking at it.
It made its way it to a bike shop in Marin.
I rember the bike had a buffalo nickel built in to the top of stem.
To expensive to destroy off-road(I also did not have alot of money back then).

Record OR (off road) was their top of the line stuff but they just could not compete with Shimano so they dropped the mountain bike stuff in the early 90's to concentrate on the road.

...mismatch in the indexing and the cage is long enough it should work. Take into account when combining different systems, typically there's always something going to turn out slightly screwed up. More hassle than it's worth if you ask me.
For the remainder, there's nothing specific about an MTB rear derailleur. Some use a DA rear in combination with a smaller cassette to save weight and it's not uncommon to see one on a DH bike (don't remember the reason for that anymore).

Cage length has nothing to do with large cog capacity.Cage length is for wrapping chain. A short and long cage mtb RD have the same large cog capacity.There are specific differences with MTB Rd. There is also the issue of throw compatibility of the cmpy RD with a shimano shifter.

....it depends on what you mean by specific differences. Provided you stay with-in the cog and maximum wrap capacity (only logical to assume), there's no functional difference between a Shimano road or MTB derailleur. It will shift and index flawlessly whether you use road or MTB shifters. It's not like using something from another system.

The paralleogram on a MTB derailer tracks a different path,relative to the cogs,in order to handle the bigger ones.

are commonplace in the DH community....low profile, crisp shifting, and lightweight in combination with a road cassette.

The hot set up for cross country back in the early 90's was to take a 105 cage and put it on to an XT derailleur body to achieve the same performance.
bad idea...C-40

The amount of cable pull, per shift on shimano shifters is not compatible with Campy derailleurs.

Can't see why anyone would want to buy a pricey campy derailleur that wouldn't shift properly with cheap and properly functioning shimano derailleurs readily available.
