Crankbrothers Stamp 1 Gen 2 Small Flat Pedal

The Stamp 1 is where the Crankbrothers flat pedal story starts — and it starts well. The Crankbrothers Stamp 1 Gen 2 Small is the lightweight, affordable flat pedal that delivers the core Stamp experience in a nylon composite body: concave platform, adjustable traction pins, and the sealed bearing + bush axle system that keeps the Stamp spinning smoothly through mud, water, and trail abuse.

The Gen 2 update brings improved pin thread inserts for longer-lasting pin replacement cycles, updated graphics, and a refined body shape — the same great Stamp platform DNA with meaningful durability improvements under the hood.

The Small size (104x98mm) is the correctly sized platform for riders with shoe sizes up to EU 43 / UK 9 / US 10 — matching the pedal footprint more precisely to the shoe sole for the most efficient power transfer and the most connected, planted feel underfoot.

Key Features

Platform & Body

• Nylon composite body — lightweight, impact-resistant, and tough enough for trail use at an accessible price point; the composite construction absorbs vibration differently from alloy, giving the Stamp 1 a slightly damped, forgiving feel
• Small platform: 104x98mm — sized for shoe sizes up to EU 43 / UK 9 / US 10; matches the pedal footprint to the shoe for the best foot-to-pedal connection
• Concave profile — the platform curves slightly inward, cupping the foot for a planted, secure feel and reducing the leverage that would allow the foot to roll off the edge of the pedal under heavy braking and cornering forces

Pins

• 10 adjustable traction pins per side — 20 total; pins are shorter than the Stamp 3/7 for a slightly less aggressive grip profile suited to trail and all-mountain riding
• Replaceable and adjustable — screw in or out to adjust protrusion; replace individually if a pin strips or breaks
• Improved Gen 2 pin thread inserts — the primary Gen 2 upgrade; stronger, longer-lasting threaded inserts that hold pins more securely through repeated adjustment and replacement cycles

Axle & Internals

• Sealed bearing + bush system — one sealed bearing and one bushing per pedal; the bearing handles the primary rotational load while the bushing provides additional support at the outer end of the axle
• 9/16″ thread — standard MTB pedal thread compatible with all standard MTB cranks
• Stainless steel axle — corrosion resistant for wet-weather riding and long-term durability
