{"product_id":"pilo-d331-derailleur-hanger-for-trek","title":"Derailleur Hanger for Trek","description":"\u003cp\u003eThe Pilo D331 Derailleur Hanger is a precision-machined replacement dropout hanger designed specifically for compatible Trek frames. When a crash or kerb strike bends your original hanger — a common occurrence on Pune's potholed ring roads or Delhi's rougher city stretches — this small component is all that stands between you and an expensive frame replacement. Keeping a spare on hand is simply good practice for any serious rider.\u003c\/p\u003e\u003ch3\u003eOur Take\u003c\/h3\u003e\u003cp\u003eIndia's roads are unforgiving. From the sharp descent at Khandala to Chennai's crater-riddled back lanes, bent derailleur hangers are one of the most frequent workshop complaints we see. The Pilo D331 is engineered to Trek's exacting tolerances, meaning your derailleur alignment stays true and shifting stays crisp. At Rs. 3,500, it costs a fraction of a new frame or derailleur, making it an essential spare for any Trek owner who rides regularly in Indian conditions.\u003c\/p\u003e\u003ch3\u003eSizing for Indian Riders\u003c\/h3\u003e\u003cp\u003eThis hanger is a frame-specific fit — sizing here refers to Trek model compatibility rather than rider body size. Before ordering, confirm your Trek frame model and year, as hanger designs vary across Trek's lineup. If you are unsure, check the underside of your dropout or contact us with your frame serial number and we will confirm compatibility before your order ships.\u003c\/p\u003e\u003ch3\u003eCompatibility Notes\u003c\/h3\u003e\u003cp\u003eThe Pilo D331 is designed for specific Trek frame models and is compatible with both Shimano and SRAM rear derailleurs that mount via a standard derailleur hanger thread. Always carry a spare — hangers are intended to be sacrificial components that protect your frame and derailleur in a crash. Replace after any significant impact, even if the bend appears minor.\u003c\/p\u003e\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cp\u003eComplete your drivetrain maintenance kit by pairing this hanger with a quality chain lubricant suited to Indian monsoon or dry-heat conditions, a rear derailleur cable and housing set, a multi-tool with a hanger-alignment check function, and a compact saddle bag to carry the spare hanger on every ride.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"\/collections\/pilo\"\u003eExplore the full Pilo 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 Pilo 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 Pilo D331 Derailleur Hanger best used for?\u003c\/summary\u003e\u003cp class=\"cc-faq__a\"\u003eThe Pilo D331 is a direct replacement derailleur hanger for compatible Trek frames.
