{"product_id":"pilo-d378-derailleur-hanger-for-lee-cougan-polygon","title":"Derailleur Hanger for Cipollini, Lee Cougan, Polygon, Pronghorn, Whyte","description":"\u003cp\u003eThe Pilo D378 Derailleur Hanger is a precision-machined replacement dropout designed specifically for Lee Cougan and Polygon frames. If you ride hard on broken tarmac, Pune's potholed bypasses, or the sharp descents around Lonavala, a bent or snapped derailleur hanger is a matter of when, not if — and having the correct replacement on hand keeps your drivetrain shifting crisply and your rear derailleur safe from catastrophic damage.\u003c\/p\u003e\u003ch3\u003eOur Take\u003c\/h3\u003e\u003cp\u003eIndian roads are unforgiving, and a derailleur hanger is deliberately the weakest link in your drivetrain — it sacrifices itself so your frame and derailleur survive a crash or a hard kerb strike. The Pilo D378 is machined to tight tolerances, ensuring correct derailleur alignment on Lee Cougan and Polygon frames right out of the packet. For riders tackling the Western Ghats, Chennai's coastal flats, or weekend sportives in Hyderabad, carrying a spare D378 is simple, smart insurance.\u003c\/p\u003e\u003ch3\u003eSizing for Indian Riders\u003c\/h3\u003e\u003cp\u003eDerailleur hangers are frame-specific, not body-size specific. The D378 fits designated Lee Cougan and Polygon frame models — verify your exact frame model and year before ordering. If you are unsure, check the underside of your existing hanger for a part number or contact Cobbled Climbs with your frame details. No heat or climate adjustments affect fit.\u003c\/p\u003e\u003ch3\u003eCompatibility Notes\u003c\/h3\u003e\u003cp\u003eThe Pilo D378 is compatible with standard M10 rear derailleur mounting bolts and works with Shimano, SRAM, and Campagnolo rear derailleurs fitted to compatible Lee Cougan and Polygon frames. After installation, check and set derailleur alignment with a hanger alignment tool before riding. Keep a spare in your kit bag — hangers are not reusable after a significant bend.\u003c\/p\u003e\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cp\u003eComplete your drivetrain protection kit with a hanger alignment tool, a quality rear derailleur from Shimano's 105 or Deore range, derailleur cable and housing set, and a compact multi-tool that includes the correct Allen key for hanger bolts.\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 D378 Derailleur Hanger best used for?\u003c\/summary\u003e\u003cp class=\"cc-faq__a\"\u003eThe Pilo D378 is a direct replacement derailleur hanger for compatible Lee Cougan and Polygon frames.
