Upgrade Groupset?
Hi, at the moment I have a Bianchi 928 C2C. This came with a full carbon frame and 105's with an FSA crank. I have done 4,200 ish miles on it and can't quite tune the rear gears correctly. I'm debating, whether after this milage, it's worth upgrading all the components to Ultegra SL (

Is it worth it?

To answer the question you need to assess why the gears can not be tuned. Is the chain and/or cassette worn out? It would be a lot cheaper to replace a chain and cassette.

I have an ultegra groupo myself and my gf has 105. I really don't see the additional value of the ultegra components as I'm not weight obsessed.

I would find out why you can't get the gears setup first...

Properly tuned 105 > improperly tuned Ultegra (or DA for that matter).

(And after 4200 miles it is probably time for a new chain and cassette)

I think the derailleur has worn to be honest. I can get the high and low done but it's the changes in between. I've changed the cable, cleaned the housing etc but to no avail.

Calaso, that's what I was thinking about the chain and casette....but then I thought why not change the lot (if it's worth it!)

It is not worth it. Replacing the cable and cleaning the housing is an inadequate compromise - the housing wears more than the cable and has as much or more effect on the shifting.

A worn chain also affects shifting... the chain loses lateral rigidity when worn and you loose more of the side-force from the derailleur in the flex.

Good news, though! If you replace your chain and cassette, and you still think you need a whole new set of parts, you can use the new chain and cassette with all the other parts you buy.

New chain ordered. I've just put a new carbon 50 on it that has it's own cassette, so we'll see if that's the problem.
