{"product_id":"ks-d241s","title":"Sintered Hayes Stroker Ace 4 Piston Disc Brake Pads","description":"\u003cp\u003eThe Kool-Stop KS-D241S is a sintered disc brake pad engineered for Hayes Stroker Ace 4-piston calipers. Built with a copper-plated backing plate and a sintered friction compound, these pads are designed to handle the kind of punishment that aggressive descents and demanding conditions throw at them — making them a strong choice for riders who push hard on steep technical terrain.\u003c\/p\u003e\u003ch3\u003eOur Take\u003c\/h3\u003e\u003cp\u003eFor riders tackling the ghats around Pune, Lonavala, or Khandala, where long descents demand consistent stopping power even when rims run hot and hands start to fatigue, the KS-D241S delivers. The sintered compound maintains friction performance under sustained braking loads, and the copper-plated backing plate adds structural integrity where it matters. If you run Hayes Stroker Ace 4-piston calipers, this is a pad worth keeping in your toolkit before every big ride.\u003c\/p\u003e\u003ch3\u003eSizing for Indian Riders\u003c\/h3\u003e\u003cp\u003eThese pads are caliper-specific — they fit Hayes Stroker Ace 4-piston systems only. There is no size variation by rider weight or build. Riders in high-humidity regions like Kolkata or coastal Chennai should note that sintered compounds handle moisture and heat particularly well compared to organic alternatives, making them suitable year-round including through the monsoon season.\u003c\/p\u003e\u003ch3\u003eCompatibility Notes\u003c\/h3\u003e\u003cp\u003eDesigned exclusively for Hayes Stroker Ace 4-piston disc brake calipers. The spring is included. Not compatible with other Hayes caliper models or third-party 4-piston systems. Clean rotors with isopropyl alcohol before installation. Bed in pads properly with a series of progressive stops to achieve full contact and consistent braking performance.\u003c\/p\u003e\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cp\u003eComplete your braking setup with compatible disc brake rotors, hydraulic brake fluid, brake bleed kits, and rotor truing tools. Riders doing sustained descents in Coorg or Ooty will also want to look at heat-management accessories and lever upgrades that complement high-performance pad compounds.\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-D241S best used for?\u003c\/summary\u003e\u003cp class=\"cc-faq__a\"\u003eThe KS-D241S is best suited for aggressive mountain biking and downhill riding where sustained braking over long descents is required.

Sintered brake pads like the KS-D241S are specifically formulated for demanding environments including wet monsoon conditions and high-heat riding above 35°C. Unlike organic pads, sintered compounds do not degrade as quickly when exposed to water, mud, or heat, making them well suited to Indian riding conditions across all seasons.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails class=\"cc-faq__item\"\u003e\u003csummary class=\"cc-faq__q\"\u003eHow does the KS-D241S compare to organic disc brake pads?\u003c\/summary\u003e\u003cp class=\"cc-faq__a\"\u003eSintered pads like the KS-D241S offer superior durability, better heat resistance, and more consistent performance under extreme conditions compared to organic pads. Organic pads tend to feel slightly more progressive and quiet initially but wear faster and can fade under sustained braking. For downhill use or heavy riders on long descents, sintered compounds are generally the better long-term choice.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails class=\"cc-faq__item\"\u003e\u003csummary class=\"cc-faq__q\"\u003eIs the Kool-Stop KS-D241S worth the price in India?\u003c\/summary\u003e\u003cp class=\"cc-faq__a\"\u003eFor riders running Hayes Stroker Ace 4-piston calipers, the KS-D241S offers genuine value through its durability and all-condition performance.
