R. Der. replacement - remove cage or break chain for install?rockbender

I'll be swapping out a rear der. tonite -

should I just split the cage of the der. for installation or split the chain and fork out the $1 for the replacement pin?

From previous experience, I try to minimize the number of times I split a chain.

Any advice would be appreciated!
No need to do eitherKerry

Remove the bolt that holds the lower pulley, and drop the pulley out. You may have to loosen - but not remove - the upper pulley bolt. The chain drops right out so your can remove the old unit, and slips right in so you can install the new one..

that's what I thought, and I've done that before but was wondering if there was one way that was better than another. Installing a new XTR der. on my girlfriends CX bike and she wouldn't be to happy if I screwed something up!

Don't forget a drop of blue locktite on the pulley bolt before you reinstall it. Nothing ruins a ride quicker than losing a jockey wheel at 22mph. Well, maybe that's overstating it, but they are hard to find after they come loose. Better an ounce of prevention. Also a good time to clean/lube the pulley.
