I'm in the process of a getting a new road bike having previously ridden mtb and a hybrid. The new bike sports a 105 12-28 (11-28 tooth) with Ultegra rear derailleur and a 54/34 chainring but I would like to switch to a 11-32 to take the pressure off my rugby ravaged knees until the weight falls some more!! What else might I have to change? Chain, rear derailleur? Any advice greatly appreciated.

Your chain will need to be 1 incn longer so thats a new chain and you will also need a medijm cage rear mech.http://www.thecycleclinic.co.uk -wheel building and other stuff.0

You could investigate a 33 (front) chainring. They used to be available for 10-sp Shimano - I don't know if someone makes one for 11-sp (or if it's possible). Then you could fit a 30t rear cassette (assuming they're also available for 11-sp) without needing to change the derailleur or, probably, the chain.ROAD < Scott Foil HMX Di2, Volagi Liscio Di2, Jamis Renegade Elite Di2, Cube Reaction Race > ROUGH0

Thanks guys for the advice. New cassette and chain it is and will double check on the mech.0

If you haven't pressed the button yet then serious consider getting a triple chainset. That will give you a better range of lower gears plus you won't lose out on either big jumps between gears or top end once you lose a bit of weight.Bianchi Infinito CV

Actually, if you need a GS Ultegra rear mech, I have one I've just taken off (unused) a new bike (that runs a 32 cassette) that I was just about to put on eBay so PM me if you're interested.ROAD < Scott Foil HMX Di2, Volagi Liscio Di2, Jamis Renegade Elite Di2, Cube Reaction Race > ROUGH0

This would also require a new front shifter too, which isn't cheap and also limits what groupset you can run.If you haven't pressed the button yet then serious consider getting a triple chainset.

Fair enough, although that means that he'd be limited to Tiagra or below.0 -
I switched from a 28T to a 32T - I already had the medium cage and didn't need to change the chain length.0

When I returned to road cycling at the age of 50 and following knee surgery I specced a triple. (Fortunately 105 came as a triple option back then) The 30t granny ring coupled with a 12-27t cassette gives me plenty of scope for spinning at the end of a long ride or on anything steep.
Sounded like the OP had already committed to the purchase of a 105 double though, so the advice above re bigger sprockets is the only really cost-effective option.0 -
He's not limited to Tiagra as you can get Ultegra Triple chainsets:This would also require a new front shifter too, which isn't cheap and also limits what groupset you can run.If you haven't pressed the button yet then serious consider getting a triple chainset.

I was referring to any of the current Shimano groupsets. Obviously.0 -
Okay fair enough, I was just pointing out you could still buy an Ultegra triple if you wanted. However I recently bought a Tiagra triple chainset for my Audax bike and it's great.
