Jagwire elite CR1 160+180mm Rotor Set Heat build-up in hydraulic brake pads, rotors and calipers is one of the critical causes of lost braking performance. Jagwire’s new 3-piece rotor design greatly reduces heat build-up by pulling heat away from the braking surface and dissipating it before it affects braking power. The key feature of these rotors are the integrated cooling fins. Made of aluminum to keep weight to a minimum, the addition of these fins reduces heat by pulling it away from the braking surface and quickly dissipating it before it can affect the caliper and brake pad. Lower temperatures = enhanced braking performance. The high-quality, stainless steel machined braking surface ensures consistent stopping power and superior modulation Lightweight, aluminum cooling fins pull heat away from the braking surface and quickly dissipate it before braking performance is affected The spider design ensures compatibility with 6-bolt designs NOTE: CR1 rotors are NOT compatible with brakes when the pad extends below the caliper body. Examples include Avid BB7, Avid Juicy, Hayes HFX, and Hayes MX1 https://jagwire.com/products/brake-rotors/disc-brake-rotors rm8 postage to peninsular malaysia rm15 for Sabah & Sarawak COD Petaling Jaya SS2 interested sms or whatapp me 016-249 1052 http://www.wasap.my/60162491052 http://bicyclebuysell.com/#!brand=&page=1&priceFrom=&priceTo=&search=davidcheng&tab=search
