Specialized tarmac drivechain
Just bought a 2014 SL4 tarmac second hand. Absolutely love the frame but the Sora components not so much. Temped to grab 105 groupset and replace it all.
Would like to know what my options are because the current drive chain is running 52x36, 11-30 casssette, 9 speed, FSA Gossamer, BB30. Would 9 speed triple/compact be compatible and if so, would it require any mods? Also if I wanted to go to 10 or 11 speed then would this cause any issues?
Thanks

Going to 10-speed would just require new shifters and a 10-speed chain - everything else will still work together.
11-speed is a whole new ball game and would require new everything except probably the chainset. In addition you will need a new wheelset unless you can convert the 9/10 freehub to an 11-speed
This I've set my sights of minimum 105 10 speed compact.
Which is a double of course. So why not go 11sp if you're not going to a triple?
Only thing I was worried about is the diameter/length of BB and what cranks will fit.
Be going for either 105 or ultegra compact group. See what deals I can find for it.
Will just go for 105 shifters, cassette and chain then :-)
