The Crankbrothers Stamp 1 Gen 2 is the kind of flat pedal riders buy once and stop thinking about—because it just works. Better grip, better foot support, better durability, and a true concave platform that feels planted whether you're riding trail, gravel, DJ, BMX, or daily commuter miles.
This updated Gen 2 version improves the original Stamp 1 with a thinner concave profile, stronger internal bearing system, and one-piece replaceable pins that deliver noticeably better traction and easier long-term service.
The small size is designed for riders with smaller shoe sizes who want proper platform support instead of oversized pedals that feel vague underfoot.

Compatibility & Technical Notes
Good Fit: mountain bikes, gravel bikes, dirt jump bikes, BMX, commuters, fitness bikes, and riders preferring flat pedals over clipless systems.
Not A Fit: riders specifically wanting clipless pedal engagement or oversized large-platform pedal sizing for very large shoes.
The small size matters—this is not just a color choice. Crankbrothers uses size-specific platform design, and correct sizing improves foot support and control significantly.
Service / Ownership Context
Flat pedals are one of the highest-impact upgrades for rider confidence. Better grip means better control, especially for newer MTB riders, technical gravel descents, and aggressive trail riding.
The upgraded IGUS internals and serviceable bearing system make these much better long-term ownership pedals than cheap sealed platform pedals that get sloppy and disposable.
Fit & Use Signals
Best for:
- Trail mountain biking
- Gravel riding with flat pedals
- Dirt jump and BMX riding
- Urban commuting
- Riders learning technical descending
- Flat pedal preference over clipless systems
Not ideal for:
- Road cycling clipless setups
- Riders needing SPD or road cleat engagement
- Very large shoe sizes needing larger pedal platforms
The biggest mistake here is riders buying the wrong size platform. Small and Large are not marketing terms—they materially change foot support and control. Smaller riders often feel much better on the Small pedal instead of oversized platforms. The Gen 2 version is a real improvement over older Stamp 1 pedals. Better concavity and better internals are immediately noticeable. Flat pedals are often a smarter confidence upgrade than drivetrain upgrades for newer MTB riders.
