Used SRAM Force 22 compact chainset, 172.5mm crank length, 50 34 chain rings 110mm BCD. Bought used as part of a groupset, but BB30 doesn’t fit the bike I put it on. Great condition, a few minor scuffs and some marks from shoe rub (swirls) on the crank arms, but just to the lacquer really. Chain rings not much wear, axle has some paint wear where the bearing would be but assume this is normal. Clear spacer that came with it when I bought it included - sold as seen, you may need adapters/washers, I’m not familiar with bb30.

Brand-new, removed from a new bike completely unused when I swapped group sets over These seem to be quite hard to find in 44T at this (fairly standard) crank length, but I think I have priced the lowest out there. Let me know any questions, thanks
