**Organic VX Pads** are specifically designed to give the best performance under normal conditions. The organic compound gives improved noise reduction as well as increased ‘bite’.**Sintered VRX Pads** are a harder compound pad with increased carbon content. Sintered pads are designed to deliver maximum performance under stress and extreme conditions. Consistent through sustained riding they are ideal for hydraulic brake systems.**Competition VRS Pads** are specifically engineered for competition riding: with an advanced pad compound comprising of, Kevlar for high frictional properties, high ceramic content for improved wet weather performance and a increased copper content for superior low speed braking characteristics. In addition a 'grooved' backing plate improves the airflow between the piston and the pad, keeping the brake system cooler and performance consistent.**Compatibility*** Clarks Clout 1* Clarks E-Clout* Clarks Clout Plus* Clarks M2* Clarks M2 Junior* Clarks S2* Clarks HD-M3000/3000 PLUS* Clarks CHM-08* Clarks CMD-23* Clarks CMD-25* Clarks CMD-27* TPR Spyre* TPR Hylex* Tektro Auriga* Tektro Draco* Tektro Dorado* Tektro Orion* Tektro Aquila* Tektro HDC300* Shimano Deore BR-M515* Shimano Deore M475* Shimano Deore M525* Shimano Deore M465* Shimano Deore M495
