Cassette Question??

OCRoadie

Here's an easy/stupid question. Can I run an Ultegra 10 spd cassette on an otherwise full Dura Ace drive train. I am currently running DA 10 spc with a 12-25. I need a 12-27 for upcoming rides but don't want to blow $150 on a cassette that I'll use a couple of times per yer. Wheels are Mavic SL's if that matters. Thanks for your help.

There should be no problems except possibly a problem with the chain being too short to make the big/big combination.

That's what I thought, if the chain currently fits my 53/25 combo do you think it will fit the 53/27? Or do I just need to try it and see? Also, does the rear DR need to be adjusted after switching? Sorry for the ignorant questions, I haven't worked on my bikes much myself, but figured something easy like this would be a good place to start:)

You may have to fiddle with the RD B tension screw to get the top pulley to clear the bigger cog.

Thanks for the replies, do I just need the cassette lockring tool and a chainwhip (besides the know-how), as you've recomended to many others, Boudreaux, I am referencing Park Tools site for instruction.

Not much to it. Chainwhip and a lockring tool, and a wrench to turn the lockring tool.

an impact wrench with lockring tool will take them right off without
a chainwhip. Its analogous to removing a lug nut on a unsupported car wheel.

Come on... doesn't everyone use a 1/2 inch impact wrench when adjusting the derailler limit screws??? :D

Cappy...derailleur screws which take a bit more finesse are best adjusted with
fine sawzall blade. Barge-troll adjusts his with that knarly black (with yellowish tint) finger nail...that is on the one hand that has fingers left.
Barge-troll...fess up 'ol geezer...your hat says "the fiend" and people cross the street when they see you comin'. Whoaaaaa.
:D...like them pearlies? I love f-ing with you man.
