Crankbrothers Stamp Flat MTB Pedals - Concise, Grippy Platform

Our review of the Crankbrothers Stamp 1 Gen 2 pedals finds them best suited to riders who want a reliable, lightweight flat platform with excellent traction for varied riding. The single biggest reason to buy is the redesigned concave profile combined with robust one-piece pins, which together deliver confident foot placement and reduced slip on technical trails or daily commutes. These pedals balance low weight and durable construction, making them a solid choice for MTB, gravel, BMX, and commuter use where consistent grip and serviceability matter.

Key Features

• Concave profile: The 1mm-per-side concavity cradles the foot and improves lateral stability for precise foot placement.
• Replaceable pins: Ten one-piece metal pins per side bite into shoe outsoles to provide consistent traction and reduce pedal slips.
• Upgraded internals: Igus bearings, seal system and a chromoly spindle borrowed from higher-end models improve long term durability and serviceability.
• Lightweight construction: At 321g per pair for Small and 384g for Large, they keep rotating mass low without sacrificing strength.
• Versatile design: The platform suits multiple riding styles from mountain biking to commuting thanks to a stable, grippy surface and reinforced composite body.
• Size-specific fit: Two platform sizes are available to create a better shoe/pedal interface for different shoe sizes, improving control and comfort.

Who It's For

The Stamp 1 Gen 2 pedals are ideal for riders who prefer flats over clipless systems and need reliable grip across trail, gravel and urban riding. Mountain bikers who take frequent pedal strikes will appreciate the reinforced composite body and replaceable pins that hold up to hits while remaining serviceable.

Riders looking for the absolute lightest premium race flat or those who need extremely wide platforms for specialty shoes may want to consider other models, but most casual racers, commuters and e-bike users will find the Stamp 1 Gen 2 a balanced choice.

Frequently Asked Questions

Are these pedals serviceable?
Yes. The Stamp 1 Gen 2 uses serviceable internals and has available refresh kits so bearings, seals and pins can be maintained or replaced.

Which size should I pick for my shoe size?
Choose Small for US M shoe sizes 5-10 and Large for US M sizes 10-15 to get the intended platform fit and control.

Do the pins damage shoes quickly?
The metal one-piece pins offer superior traction but can increase outsole wear compared with smooth platforms; many riders accept that trade-off for better grip.
