Derailleur Hanger for Giant, Trek

The Pilo D490 Derailleur Hanger is a precision-machined replacement dropout designed specifically for Trek frames. A small part that carries enormous responsibility, the derailleur hanger is your drivetrain's first line of defence against impact — and having a spare on hand is essential for any rider tackling the potholed climbs of Lonavala, the broken tarmac of Delhi's outskirts, or gravel descents around Coorg.

Our Take

Indian roads are unforgiving, and a bent or snapped derailleur hanger can end a ride instantly. The Pilo D490 is machined to tight tolerances, ensuring a precise fit that keeps your rear derailleur aligned and your shifting accurate. For Trek owners riding the Western Ghats or grinding through monsoon-softened roads around Pune, carrying this hanger as a spare is simply smart preparation. Pilo's quality control means you won't be fumbling with a loose or misaligned fit trailside.

Sizing for Indian Riders

This is a frame-specific component, not a sized product — there is no S/M/L selection required. What matters is your Trek frame model and year. Verify your frame's compatibility before ordering. Pilo uses a model-number system (D490) that corresponds to a specific Trek dropout interface, so double-check against your frame's documentation or contact Cobbled Climbs for confirmation.

Compatibility Notes

The D490 is engineered for specific Trek frame models — confirm compatibility with your frame year and model before purchase. It is compatible with standard rear derailleur mounting systems used on those frames. Store spare hangers away from direct heat and moisture, particularly important during India's humid monsoon months, to prevent corrosion of the aluminium alloy construction.

Pairs Well With

Complete your drivetrain protection kit with a rear derailleur from Shimano or SRAM, a quality chain and cassette for smooth shifting, a multi-tool with the correct allen keys for trailside installation, and a compact saddle bag to carry this hanger on every ride.
