Clarks CFR-10FA Floating Disc Brake RotorWith a strong and lightweight 7075 alloy inner section and top-end stainless-steel braking area, the CFR-10FA Floating Disc Brake Rotor will help you to get the best from your road, mountain bike (MTB) or hybrid bike’s brakes. The alloy inner spider draws heat away from the braking surface to prevent the dreaded “brake fade” on long descents. Plus, Clarks has drilled 150 holes in the area that your brake’s pads contact, further reducing heat build-up and helping to disperse dirt and water too.Brake Rotor with Rounded EdgesThe braking surface on this rotor has a very round edge with very few recesses. Clarks made it like this so that the disc pads consistently make 100% contact with the disc no matter where they are applied. This drastically improves your overall braking power.Features:Material: Braking Surface: Stainless-Steel; Carrier: Aerospace Grade 7075 AlloyUse: Road, Mountain Bike (MTB), HybridMount Type: Standard 6-boltCompatibility: All Clarks mechanical and hydraulic disc brakes and other brands tooPrecision drilled braking band with 150 holes to encourage efficient heat dispersionResistant to warpingManufacturer’s Part Number: CFR-10FAWeight: 160mm: 122g; 180mm: 144g; 203mm: 152gBuy Clarks Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
