These Full FlashPro brake shoes are a shoe and pad combo. They will work with virtually any brake caliper. They are sold in pairs, so one package sets up one caliper. Purchase two to set-up a complete bike with front and rear calipers. The shoes are CNC'd alloy to Shimano/SRAM spec, meaning, they accept any Shimano/SRAM compatible brake shoe. These shoes are fitted with Black Prince brake pads.
The Black Price compound, there is a more linear, natural relationship of lever force to braking force. So basically, when you squeeze the brake levers harder you will get much more braking force versus other pads. And it is easier to apply lower braking force for better fine control or feathering of brakes which the riders around you will appreciate. Braking force continues to increase progressively with lever pull and maximum braking force is increased. Increased braking force in wet conditions means 25% shorter stopping distances and much better control of braking in the rain. Maximum temperature created during high speed deceleration is significantly lower reducing the worry of excessive heat with carbon clinchers.
