SRAM SX crank arms with matching bottom bracket, arms are 175mm, 30t eagle chainring. Bottom bracket is a truvativ power spine 68mm shell, 118mm spline. Dates 07/21. Bottom bracket has new bearing replaced so runs smooth and clean. The set up was fitted to my bike for few tests, so as per photos some dirt but no damage, and anodising is wear I can note, I changed out as for me with 12speed set up I wasn't right for my riding.
