Campagnolo H0 "29-32 only"

[auto_rock]

So got a new RD in the mail, and although Campy has finally shown up to the "wide cog" party, when I took it out of the box I noticed that there's a label on the cage that says "29-32 only".

I'm assuming, though it's not spelled out in the manual, that that means you're not supposed to run a smaller large cog.

What happens if you do though? To me it seems all that would happen is the derailleur is under less tension for that position but it still should take up the chain, since it can take up the slack from the 11-39 cross-chain...

I'm assuming it'll work but... it's campy, so who knows! Before I go down this road wondering if I should switch back to a standard cage and run the ratios I know go...

Sounds like they took a note from Shimanos playbook. It will be fine. Run it.

I agree, it will most likely run fine.

Nothing..those pesky Italians..Just install, make sure the chain length is proper and go ride...People have been using longer cages for smaller cogs for geez...75 years....:eek: Not a der but you get the idea..way to take up chain slack.

I'm actually trying to go the other route with my HO RD. Next freewheel purchase will be a 11-34!
