The Crankbrothers Stamp 1 Gen 2 is an affordable, high-performance nylon composite flat mountain bike pedal. Completely overhauled from the original version, the Gen 2 directly addresses previous complaints of a center axle bulge by introducing a true concave body profile and upgraded internals borrowed straight from the premium aluminum Stamp 7 model.
Core Technical Specifications
Body Material: Impact-resistant Nylon Composite.
Spindle Material: Forged SCM 435 Chromoly Steel.
Internals: Fully serviceable Igus LL-glide bearings and a robust Enduro seal system to lock out moisture.
Stack Height: Ultra-thin profile measuring 13.5mm at the center, tapering to 15.5mm at the edges.
Pins: 10 replaceable steel traction pins per side.
Size Options:
Small (S): 100mm x 100mm platform (Optimized for shoe sizes US 5–10 / EU 37–43).
Large (L): 114mm x 111mm platform (Optimized for shoe sizes US 10–15 / EU 43–49).
Key Upgrades & Trail Performance
True Concave Profile: The pedal cups the sole of your shoe naturally by slimming down the center core. This design allows your shoe to settle deeply into the pedal rather than resting on top of the spindle axis, resulting in a much more planted and secure ride.
One-Piece Hex Pins: The Gen 2 utilizes top-loading, one-piece threaded pins. Unlike the original model's through-bolts, these pins offer superior structural bite into flat cycling shoe rubber.
Upgraded Internals: The identical bearing, spindle, and dual-seal system of the award-winning Stamp 7 ensure the entry-level Stamp 1 rotates smoothly and is easily rebuildable with standard Crankbrothers refresh kits.
Performance Considerations
Reviewers from platforms like The Loam Wolf and Bike Perfect highlight that the composite body slides smoothly over rocks and roots, minimizing severe rock-strike catch points. However:
The pins are somewhat thick, and if paired with less-grippy, stiff-soled shoes, they won't bite as deeply compared to ultra-thin needles.
Because the pins thread directly into the composite body from the top, a heavily damaged pin can occasionally be trickier to back out if the head is sheared off completely on a rock.
