Description
The Pilo D187 Derailleur Hanger is a precision-machined replacement dropout hanger designed specifically for BTWIN and Decathlon bicycles. If you have snapped a hanger on a rough patch of road near Pune or during a loaded commute in Delhi, this is the part that gets you riding again without replacing the entire rear dropout or frame. Stocking a spare is simply sensible practice for any regular cyclist.
Our Take
Indian roads punish drivetrain components hard. Potholes on the outskirts of Hyderabad, sudden kerb drops in Chennai, and the occasional gravel spill on the Lonavala descent all apply lateral stress directly to the derailleur hanger — a component deliberately designed to snap before your frame does. The Pilo D187 is machined to tight tolerances, fits the BTWIN geometry correctly, and restores precise shifting. Keeping one in your saddlebag or toolkit is a low-cost insurance policy every BTWIN rider in India should take seriously.
Sizing for Indian Riders
Derailleur hangers are frame-specific, not rider-specific, so body size and fit are not relevant here. What matters is verifying your exact BTWIN or Decathlon frame model before ordering. The D187 designation corresponds to a specific dropout interface — cross-check against your frame's model number or the Pilo compatibility chart. If you are unsure, photograph your existing hanger and contact Cobbled Climbs before placing your order.
Compatibility Notes
The Pilo D187 is compatible with specific BTWIN and Decathlon bicycle frames only. It works with both Shimano and SRAM rear derailleurs that mount via a standard M10 hanger bolt. Always check thread pitch and hanger profile against your frame before installation. Use a derailleur hanger alignment tool after fitting to ensure accurate indexing across all gears.
Pairs Well With
Complete the repair properly by pairing this hanger with a rear derailleur cable and housing set, a derailleur alignment gauge for precise installation, a chain wear indicator tool to check chain condition after a hanger-snapping impact, and a compact multi-tool to carry on rides so you can swap hangers roadside if needed.

Frequently Asked Questions
What is the Pilo D187 Derailleur Hanger best used for?
The Pilo D187 is a direct replacement hanger for BTWIN and Decathlon bicycle frames. It is used when the original hanger has bent or snapped after an impact — a common occurrence on Indian roads with potholes and unexpected surface changes. Replacing the hanger restores accurate rear derailleur alignment and smooth gear shifting.
How do I know the Pilo D187 is the correct hanger for my BTWIN bike?
Cross-reference your BTWIN or Decathlon frame model number against the Pilo D187 compatibility specification before ordering. The model number is typically on a sticker near the bottom bracket. If you are uncertain, photograph your existing hanger or broken dropout and contact Cobbled Climbs — our team can confirm fitment before you purchase.
Will the Pilo D187 hold up on Indian roads and in monsoon conditions?
Derailleur hangers are intentionally the weakest link in the drivetrain — they are designed to break so your frame does not. The Pilo D187 is machined from quality alloy and will perform identically to the original in all conditions, including monsoon riding in Mumbai or dusty roads around Rajasthan. Carry a spare; replace as needed.
How does the Pilo D187 compare to a generic or local replacement hanger?
Generic hangers often have imprecise tolerances that result in poor derailleur alignment and inconsistent indexing. The Pilo D187 is machined specifically for BTWIN dropout geometry, meaning thread pitch, hanger angle, and profile are exact. This translates directly to accurate shifting and a hanger that seats correctly the first time without filing or modification.
Is the Pilo D187 worth Rs. 4,400 and what warranty does it include?
At Rs. 4,400, the Pilo D187 is far more cost-effective than sourcing an original BTWIN hanger through a service centre or risking frame damage from a poorly fitted generic part. Pilo products are covered under standard manufacturer warranty against material and machining defects. Contact Cobbled Climbs for warranty claims and support across India.
