It's currently got an unholy mash-up of 9spd 105 STI, some MTB FM, middleburn cranks with a 3x, a Deore mech from an Orange Sub5 circa 1998/9 and what I think is an XT 9spd block up to 32. Also running BB7s.
Rear shift is fine though the range is rubbish for me (a riding style that's fine until I get a bit cracked at which point I really quite like low, twiddly gears). But the FM is an absolute dog, renowned for being so IIRC (something to do with MTB FM / cranks and STI shifters, iirc).
So, what do I change to run a 2x10 or even a 1x10 with a small chain ring? I thought about GRX but the frame is IS mount and that group is flat mount. So, shifters that can run cable brakes would be handy.
My thoughts were secondhand 10spd STI, uno the middleburns and a smallish front ring, new wide range 10 spd cassette and whatever RM is workable from spares box.
Thoughts, cock-ups, incompatabilities, alternatives and potentially FS gear that might achieve this all welcome.
