Well, due to continuous nagging from my brother and GCN making a lot
of claims and how much trouble I had at the Grizzly Peak Century I
decided to go from my 29 large cog to a 32.

Well, Campy doesn't make an 11-32 or anything else with a 32 for that
matter. These are common on Shimano and SR 10 speed bikes.

I finally discovered that Interlock makes a 10 speed 11-32 and went
to several shops who couldn't get that gear.

Finally I went to Robinson's Wheel Works only 2 miles from my home.
Chris really is a knowledgeable mechanic and when I said what I
wanted he said to NOT buy Interloc anything because they don't shift
properly and wear out rapidly.

He also said that the Campy rear derailleur wouldn't shift anything
larger than a 29. I told him that I was getting a mid-length rear
derailleur and he said that it still wouldn't shift a gear lower than
29.

Then it occurred to me that I had seen that problem on a Campy triple
I had built. If you get the chain length correct the upper arms
doesn't have enough motion to lift out of the way of anything larger
than a 28. If you pull a link out it CAN shift a 29.

So I will have to get a conversion set of 11 speed Campy to go to a
gear set that large and that is now so expensive that I will have to
weight a long time.


Not sure if someone else has already mentioned, but you can get a
bracket that mounts the derailleur a bit lower so it can accommodate
bigger sprockets.
