{"product_id":"ks-d640","title":"Organic Shimano Zee\/Saint Disc Brake Pads","description":"\u003cp\u003eThe Kool-Stop KS-D640 disc brake pads are engineered for riders who demand consistent stopping power across varying terrain and weather conditions. Compatible with a carefully selected range of Shimano hydraulic disc brake systems, these pads bring dependable performance to trail, enduro, and all-mountain riding — qualities that matter whether you're descending the Western Ghats or navigating the rain-soaked lanes of Pune during monsoon season.\u003c\/p\u003e\u003ch3\u003eOur Take\u003c\/h3\u003e\u003cp\u003eKool-Stop has long been trusted by serious cyclists for pad compounds that hold up under real-world stress. The KS-D640 is no exception — its compound is well-suited to the demanding braking scenarios Indian riders face: long descents on Ooty and Lonavala roads, combined with heat exceeding 35°C that can accelerate brake fade on cheaper alternatives. For mountain bikers running Shimano Zee, Saint, or Deore XT, these are a reliable upgrade worth carrying in your kit bag.\u003c\/p\u003e\u003ch3\u003eSizing for Indian Riders\u003c\/h3\u003e\u003cp\u003eDisc brake pads are not sized by body measurement but by brake system compatibility. Confirm your specific Shimano brake model before ordering — the KS-D640 fits Shimano Zee BR-M640, Saint BR-M810\/M820, Deore XT BR-M8020, and MT420\/520, M7120, M9120 callipers. If you are unsure of your brake model, check the calliper body for the model number stamped or printed on the housing.\u003c\/p\u003e\u003ch3\u003eCompatibility Notes\u003c\/h3\u003e\u003cp\u003eThe KS-D640 includes the spring and is compatible with Shimano Zee BR-M640, Saint BR-M810 and BR-M820, Deore XT BR-M8020, and MT420\/520, M7120, M9120 systems. These are hydraulic disc brake pads — not suitable for mechanical or rim brake systems. Replace pads before they wear below the minimum thickness indicator to protect your rotors.\u003c\/p\u003e\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cp\u003eComplete your braking setup with quality disc brake rotors in the appropriate size for your wheel diameter and riding style. A hydraulic brake bleed kit ensures your system stays sharp after hard use. Pair with all-mountain or enduro tyres for trail grip, and a cassette and chain suited to your Shimano drivetrain groupset.\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-D640 best used for?\u003c\/summary\u003e\u003cp class=\"cc-faq__a\"\u003eThe KS-D640 is best suited for trail, enduro, and all-mountain riding where sustained braking performance matters.
