I would prefer SRAM apex/rival 175 compact with 34 inner ring but also open to shimano tiagra/105/ultegra.
I have a R700 shimano crankset (ultegra/DA level i believe). 50/34T. 175mm arms. it came on a bike with full DA 7800 (since there is no 7800 compact crankset) - i really want to trade it for a standard crankset to complete my 7800 bike, but would consider selling it.
I have and used FSA k-force crankset w/ bottom bracket for sale $90 shipped.
PM if you’d like pics.
Have a brand new Ritchey WCS 175 with 50/34 rings. Takes Octalink BB. Will sell for $90 shipped.
