This is a set of Shimano Saint FC-M800 2pc HollowTech II cranks made in Japan. In Black. 175mm length. For 9/16 peddles. They were originally designed for mountain bike use but can be used for BMX racing bikes. I have them on 3 of my BMX race bikes at a fraction of the cost of the Shimano DXR cranks. Crankset with spindle only Peddles chainring etc. not included.
