WTD: Swap my Dura Ace chainset (52/39) for your compact
I'm not strong enough to push a big ring up proper hills, so I'd like to swap my dura ace chainset for an equivalent compact.
It's 7800, in very good nick - a few of the usual scuffs but nothing bad. Teeth look good too, hasn't done too many miles. Crank length is 172.5mm.
I'm looking for 7850, or similar - I'll consider SRAM, FSA etc . gotta be compact though.
