Digital STL | Derailleur Shield Protector

• TPU 95A construction: flexes, wraps, and deflects impacts instead of cracking
• Silent protection: no clank, no vibration
• Proven on trail: tanked rock hits all summer and kept the derailleur safe
• Secure mount: zip-ties directly to the chainstay and does not move

Honestly, this thing feels indestructible. Mine has taken multiple direct hits and just bends and rebounds, my drivetrain was saved at least 3 times last summer.

This is a digital STL file. Print the guard yourself — no physical item is shipped. You have 3 downloads maximum from Shopify.

All 3 versions are included.

• Mounts with 4 zip-ties on the chainstay
• Install with the chain on the smallest cog

• Material: TPU 95A only (must flex, don’t print in PLA/PETG)
• Nozzle: 0.4 mm or 0.6 mm
• Layer height: 0.2 mm (0.4 nozzle) or 0.3 mm (0.6 nozzle)
• Walls: 4
• Infill: 75% minimum, lower infill bends too easily
• Supports: none

Note: TPU prints take time, but it's worth it!

TPU prints this size take time and are expensive to batch-produce. Instead of pricing it high, I'm sharing the STL so riders can print it themselves, this part works too well to keep to myself.
