ImpactCore Crank Shield
“Normal crank protectors didn’t feel like they were absorbing anything. I could feel the hits straight through my legs.”
Designed by a physics engineering student and lifelong downhill rider, the ImpactCore Crank Shield fixes what other protectors miss. It’s made from thick 4.0 mm TPU 95A and engineered to flex and flatten under impact, acting more like a damper than a decorative cap.
Material & Finish Notes
This part is 3D printed in black TPU. Expect light surface texture and minor internal stringing. TPU 95A is extremely hard to print cleanly, this product is tuned for durability, not aesthetics. If you want flashy colors or glossy plastic, this isn’t the product. This is for real protection.
Key Features
Installation requires firm pressure. The tight fit is intentional, it prevents movement and ensures maximum protection.
20 mm diameter hole fits SRAM GX, NX, XO Carbon, and T-Type cranks. Not compatible with OneUp pedals unless you order the custom tip option.
Crank Compatibility
- Compatible with SRAM GX, NX, XO Carbon, and T-Type
- Not yet tested with Shimano or RaceFace
- Custom tip options available for OneUp pedals
Engineered for Real Impact
Most crank protectors use thin, hard plastics that deflect but don’t dampen. The ImpactCore uses elastic deformation and material compression to absorb energy before it reaches your crank. The entire geometry, wall thickness, flex region, TPU hardness, was tuned through real-world testing.
