Clarks: The M3, delivers superior looks with an alloy cast radial style lever. We have engineered out a large amount of weight from the brake system as well as drastically improving the overall aesthetics. The radial design lever increases the room available on the handlebar so creating a cleaner look on the bike. Calliper weight and aesthetics have also benefited from alloy casting as well as the systems ability to deal with heat build-up. The M3 uses 2 pistons per calliper, and with a large internal fluid capacity braking power is improved by 25% compared with the M2. The M3 will to appeal to many riders from leisure cyclists to the dedicated downhill rider.Radial style Flip Flop lever designCast alloy lightweight designRemovable handle bar clampReach  and bite adjustmentHigh quality anodised finishOne piece calliper designMineral FluidPM and IS compatibleWeight - 224gFront 180mm & Rear 160mm set
