{"product_id":"pilo-d781-derailleur-hanger-for-trek","title":"Derailleur Hanger for Trek","description":"\u003cp\u003eThe Pilo D781 Derailleur Hanger is a precision-machined replacement dropout hanger designed specifically for Trek frames. Whether you ride Mumbai's chaotic streets, tackle the switchbacks above Lonavala, or push through Coorg's forest roads, this small but critical component keeps your drivetrain shifting accurately after a crash or a kerb-strike bends your original hanger out of true.\u003c\/p\u003e\u003ch3\u003eOur Take\u003c\/h3\u003e\u003cp\u003eIndian roads are unforgiving — potholes, speed breakers, and gravel patches mean derailleur hanger damage is far more common here than it is in Europe. The Pilo D781 is cut to tight tolerances from quality alloy, ensuring proper derailleur alignment right out of the packet. For Trek owners in Pune, Delhi, or Hyderabad who rely on their bike daily, keeping a spare D781 in your toolkit is as sensible as carrying a tube. It is a modest investment that prevents a bent hanger from sidelining an expensive groupset.\u003c\/p\u003e\u003ch3\u003eSizing for Indian Riders\u003c\/h3\u003e\u003cp\u003eThis hanger is Trek-frame specific and fit is determined by your frame model, not your body size. Verify your Trek frame generation and model year before ordering — Trek has used multiple hanger profiles across different series. If you are unsure, check the model number stamped inside your dropout or contact Cobbled Climbs with your frame details. Sizing here means frame compatibility, not rider sizing.\u003c\/p\u003e\u003ch3\u003eCompatibility Notes\u003c\/h3\u003e\u003cp\u003eThe D781 is designed for specific Trek frame models; confirm compatibility with your exact frame before purchase. It works across a range of groupset standards — road, MTB, and gravel drivetrains — provided the frame dropout is the correct match. No special tools are required beyond a standard 5 mm Allen key for installation. Clean the dropout threads before fitting to avoid cross-threading.\u003c\/p\u003e\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cp\u003eRound out your workshop spares with a quality chain lubricant suited to Indian monsoon conditions, a derailleur alignment gauge for precise setup, a multi-tool for roadside fixes, and a cable and housing set to keep your shifting crisp after any drivetrain impact.\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 D781 Derailleur Hanger best used for?\u003c\/summary\u003e\u003cp class=\"cc-faq__a\"\u003eThe Pilo D781 is a direct replacement for a bent or broken derailleur hanger on compatible Trek frames.
