Derailleur and 12/27Ralph

I have a new bike with ultegra 12/25 but caming from riding a tripple I feel I need a 12/27. Can I just put a 12/27? would I need a new derailleur or a chain?

You can use the 12-27 with no problems ...same chain ...good luck ...

It's true that it will all work, but be sure to verify that your chain is long enough to ride "crossed" in big/big gearing. You don't want to do this as a habit, but sometimes you may end up there and if the chain is not long enough the drive train will jam and the rear der. will get pretty torqued. You can end up with a bent der. and/or bent hanger - been there, done that, wasn't fun. ;-( You may need to add a link (actually two links - an inner and an outer). Make sure that you use the correct pins.
