MOUNTAIN BIKE DISK BRAKE ROTORS - CRYO TREATED FLOATING

BMR2 Series rotors use the same 410 stainless steel braking surface but utilise a lightweight 7075 aluminum alloy centre. This 2 piece (or floating) design enables the braking surface to expand and contract without imparting these stresses to the hub mounting face. The rotors are double disc ground and heat treated. • 2 Piece Rotor Design • I.S. 6 Hole Mounting • 7075 Aluminum Alloy Center • Japanese 410 Stainless Steel
