Groupset upgrade

pablo3090

I have a quick question ;
current bike has a mixture of components,
Micro Shift Shifters / Front Derailleur,
FSA Chainset,
Shimano 105 rear derailleur all 10 speed.

Looking to upgrade to Shimano 105 11 speed, do I need to replace the Chainset and front derailleur or would I be able to get away with just changing the Shifters, rear derailleur and cassette

Thanks

I use an 10 speed chainset with 11 speed rear mech. It's fine for me. Not sure if 11 speed shimano shifters have a different form than 10 speed, I haven't been paying attention. I mean: they might have different hoods and be of different lengths away from the bars, or maybe not.

Oh wait, you want to change from Microshift to Shimano shifters.

I think the pull ratio on the front Shimano shifters have changed with the later front mechs so you might need to upgrade the front mech if getting the newer shifters.

Thanks Raam, will i also need to change the Chainset , or would it be compatible

I reckon it would be fine. Not ideal but I wouldn't change it unless I had to. I use 10 speed Campag chainset with 11 speed shifters/mechs. It works perfect for me.

Why don't you get an 11sp cassette and have it to use?

I only use 11 speed cassettes on that bike. It is the chainset which is 10 speed. Or rather, the chainset was built when there was no 11 speed.
