This are my Sram RED 170 (53x39) cranks, no BB. I used them this summer in the short crank experiment…yes it did work but for me the extra spinning that I gained I was able to put into my normal 175’s so they can go. SOLID CONDITION!!! $200 FREE SHIPPING in COnti US. Pic soon, but you know what they look like! No real scuffs etc.
