{"product_id":"ks-d635k","title":"Aero Kool Shimano XTR 2011 Disc Brake Pads","description":"\u003cp\u003eThe Kool-Stop KS-D635K is a forged aluminium disc brake pad designed for Shimano-compatible disc brake systems, offering dependable stopping power in varied conditions. With an organic compound formulation and integrated cooling pins, these pads are a practical upgrade for riders across India's demanding terrain — from Pune's Sahyadri switchbacks to the long descents around Ooty and Coorg.\u003c\/p\u003e\u003ch3\u003eOur Take\u003c\/h3\u003e\u003cp\u003eIndia's roads demand brake pads that perform consistently under heat, grit, and sudden rain. The KS-D635K's organic compound bites cleanly without the harsh bite-and-release of metallic pads, making it well-suited to mixed riding in cities like Hyderabad and Chennai where stop-start traffic is constant. The cooling pins on the forged aluminium back help manage heat build-up during long Western Ghats descents — a real advantage when temperatures push past 35°C in summer.\u003c\/p\u003e\u003ch3\u003eSizing for Indian Riders\u003c\/h3\u003e\u003cp\u003eThese pads are designed as a direct replacement for Shimano disc brake systems compatible with the D635 series — excluding BR-CX75, BR-R515, and BR-R315. There is no rider sizing consideration here, but verify your calliper model before ordering. The integrated spring ensures correct pad return and alignment, making self-installation straightforward even without a workshop visit.\u003c\/p\u003e\u003ch3\u003eCompatibility Notes\u003c\/h3\u003e\u003cp\u003eCompatible with Shimano disc brake callipers in the D635 range, with three explicit exceptions: BR-CX75, BR-R515, and BR-R315. The forged aluminium backing plate with cooling pins is designed for secure seating. Organic compound pads should be kept free of oil and brake fluid contamination — avoid touching the compound surface during installation.\u003c\/p\u003e\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cp\u003eComplete your braking system with disc brake rotors, hydraulic brake fluid (mineral oil type for Shimano), brake bleed kits, and disc brake-compatible wheelsets. A torque wrench is also a useful addition for precise calliper bolt tightening.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"\/collections\/koolstop\"\u003eExplore the full KOOLSTOP collection at Cobbled Climbs\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eWhy buy from Cobbled Climbs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e100% genuine — authorised KOOLSTOP retailer in India\u003c\/li\u003e\n\u003cli\u003eFree delivery on orders above Rs. 2,500\u003c\/li\u003e\n\u003cli\u003eCash on delivery available nationwide\u003c\/li\u003e\n\u003cli\u003e7-day easy returns\u003c\/li\u003e\n\u003cli\u003eShipped from Mumbai\u003c\/li\u003e\n\u003cli\u003eExpert advice — our team rides this gear\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cstyle\u003e.cc-faq{margin:32px 0 24px}.cc-faq__item{border-top:1px solid #e5e5e5;margin:0}.cc-faq__item:last-of-type{border-bottom:1px solid #e5e5e5}.cc-faq__q{cursor:pointer;list-style:none;padding:24px 0;display:flex;justify-content:space-between;align-items:center;gap:24px;outline:none}.cc-faq__q::-webkit-details-marker{display:none}.cc-faq__q:focus-visible{outline:2px solid #000;outline-offset:-2px}.cc-faq__q::after{content:\"\";width:14px;height:14px;flex-shrink:0;background-image:url('data:image\/svg+xml;utf8,\u003csvg viewBox=\\\"0 0 14 14\\\" xmlns=\\\"http:\/\/www.w3.org\/2000\/svg\\\"\u003e\u003cpath d=\\\"M2 5l5 5 5-5\\\" stroke=\\\"%23000\\\" stroke-width=\\\"1.5\\\" fill=\\\"none\\\"\/\u003e\u003c\/svg\u003e');background-repeat:no-repeat;background-position:center;transition:transform .2s ease}.cc-faq__item[open] .cc-faq__q::after{transform:rotate(180deg)}.cc-faq__a{padding:0 0 28px;margin:0}\u003c\/style\u003e\u003csection class=\"cc-faq\" aria-label=\"Frequently Asked Questions\"\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdetails class=\"cc-faq__item\"\u003e\u003csummary class=\"cc-faq__q\"\u003eWhat is the Kool-Stop KS-D635K best used for?\u003c\/summary\u003e\u003cp class=\"cc-faq__a\"\u003eThe KS-D635K is best suited for road and cyclocross riders using Shimano D635-compatible disc brake callipers who want progressive, controlled stopping power.
