{"product_id":"pilo-d731-derailleur-hanger-for-thompson","title":"Derailleur Hanger for Eastern, Conor, Evoke, Haro, Leader fox, Megamo, Thomson, WRC","description":"\u003cp\u003eThe Pilo D731 Derailleur Hanger is a precision-machined replacement dropout designed specifically for Thompson frames. A derailleur hanger is a small but critical component — when your derailleur takes a knock on a rough patch of road or trail, the hanger bends or snaps to protect your frame and drivetrain. Keeping a spare on hand is smart riding practice anywhere in India.\u003c\/p\u003e\u003ch3\u003eOur Take\u003c\/h3\u003e\u003cp\u003eIndia's roads — from Pune's crater-riddled bypass to the sharp gravel descents around Ooty and Coorg — are hard on drivetrains. A bent or snapped hanger can end a ride instantly, and sourcing a frame-specific replacement locally is often impossible. The Pilo D731 is machined to exact tolerances for Thompson geometry, meaning your shifting returns to factory precision once fitted. At Rs. 5,912, it is inexpensive insurance for a frame that costs far more to replace.\u003c\/p\u003e\u003ch3\u003eSizing for Indian Riders\u003c\/h3\u003e\u003cp\u003eDerailleur hangers are frame-specific, not body-size dependent. The D731 is designed exclusively for Thompson frames — verify your exact frame model before ordering. There are no heat or fit considerations beyond ensuring the hanger threads align correctly with your rear derailleur mounting bolt. Indian summers and monsoon humidity do not affect fitment, though regular inspection for stress cracks is advised after rough rides.\u003c\/p\u003e\u003ch3\u003eCompatibility Notes\u003c\/h3\u003e\u003cp\u003eThe Pilo D731 is compatible with Thompson frames only. It works across Shimano, SRAM, and Campagnolo rear derailleurs provided the derailleur mounting thread is standard. Always check your frame's model designation against Pilo's compatibility list before purchase. Fitting requires a basic hex key; no specialist tools needed. Inspect and replace after any significant impact.\u003c\/p\u003e\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cp\u003eComplete your drivetrain protection kit with a chain checker tool to monitor wear, a quality rear derailleur from Shimano or SRAM, derailleur limit-screw tools for post-replacement indexing, and a compact multi-tool to carry on rides through the Western Ghats or Leh's remote high-altitude passes.\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 D731 Derailleur Hanger best used for?\u003c\/summary\u003e\u003cp class=\"cc-faq__a\"\u003eThe Pilo D731 is a direct replacement derailleur hanger for Thompson frames.

Machined aluminium hangers are not affected by monsoon humidity or temperatures above 35°C. However, Indian road conditions — potholes, loose gravel on climbs around Pune, Ooty, or Lonavala — increase the chance of a derailleur strike. We recommend inspecting your hanger for stress cracks or slight bends after every rough ride and carrying a spare on longer outings.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails class=\"cc-faq__item\"\u003e\u003csummary class=\"cc-faq__q\"\u003eHow does the Pilo D731 compare to sourcing an original Thompson hanger?\u003c\/summary\u003e\u003cp class=\"cc-faq__a\"\u003ePilo machines hangers to tolerances that match or exceed OEM specifications.
