{"product_id":"pilo-d820-derailleur-hanger-for-isaac-vitus","title":"Derailleur Hanger for Isaac, Jamis, Scott, Vitus","description":"\u003cp\u003eThe Pilo D820 Derailleur Hanger is a precision-machined replacement dropout designed specifically for Isaac and Vitus framesets. If you've bent or snapped a hanger on a rough patch of road — and Indian tarmac gives plenty of opportunity for that — this is the exact replacement you need to get your drivetrain shifting cleanly again without replacing the entire frame.\u003c\/p\u003e\u003ch3\u003eOur Take\u003c\/h3\u003e\u003cp\u003eDerailleur hangers are consumable parts, and Pilo has built a reputation for getting the geometry exactly right. The D820 matches the original dropout specification for compatible Isaac and Vitus frames, meaning your derailleur alignment stays true from the first bolt-up. For riders tackling the sharp descents around Lonavala or the potholed city roads of Pune and Hyderabad, carrying a spare D820 is simply smart riding practice. Pilo's machining quality means this hanger won't introduce any slop into your shifting.\u003c\/p\u003e\u003ch3\u003eSizing for Indian Riders\u003c\/h3\u003e\u003cp\u003eDerailleur hangers are frame-specific rather than rider-specific, so sizing here means frame compatibility, not body measurements. The D820 fits Isaac and Vitus frames only — confirm your exact frame model before ordering. No heat or climate adjustments are needed for fit, but check your frame's dropout threads for corrosion, especially after monsoon riding in Chennai or Kolkata.\u003c\/p\u003e\u003ch3\u003eCompatibility Notes\u003c\/h3\u003e\u003cp\u003eThe Pilo D820 is compatible with Isaac and Vitus framesets that use this specific dropout interface. It works with both Shimano and SRAM rear derailleurs. Always check thread condition before installation and use appropriate threadlocker or copper grease to prevent corrosion seizing in humid conditions. Pilo hangers are CNC-machined from aluminium alloy for consistent tolerances.\u003c\/p\u003e\u003ch3\u003ePairs Well With\u003c\/h3\u003e\u003cp\u003ePick up a rear derailleur (Shimano or SRAM) if yours was damaged in the same incident. A chain checker tool helps you assess drivetrain wear before reinstalling. A torque wrench ensures correct bolt tension, and a derailleur alignment tool lets you verify straightness after fitting.\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 D820 Derailleur Hanger best used for?\u003c\/summary\u003e\u003cp class=\"cc-faq__a\"\u003eThe Pilo D820 is a direct replacement for a bent or broken derailleur hanger on compatible Isaac and Vitus frames.
