Bicycle Pedal Crankbrothers Stamp 1 Gen 2 — Composite/Nylon Platform, Chromoly 4140 Axle, 100×100 mm, 160.5 g (pair)

Crankbrothers Stamp 1 Gen 2 platform pedals are designed for flat-pedal riding, offering a wide 100 × 100 mm contact surface and a composite/nylon body paired with a Chromoly 4140 axle. Supplied as a pair and weighing 160.5 g per pedal, these pedals carry design elements from higher-end Stamp models — a true concave profile for improved shoe contact, robust internal bearings, and a one-piece replaceable pin design to maintain traction over time.

Advantages

The concave body design increases contact between shoe and pedal for consistent grip and stability. Durable Chromoly 4140 axle construction provides strength where it matters most while the nylon composite platform keeps weight low. Internal Igus-derived components and a serviceable bearing and seal system extend service intervals and simplify maintenance. Replaceable one-piece traction pins offer predictable grip and straightforward replacement when wear occurs.

Suitable for

• Trail riding on flat-style pedals
• Urban commuting and everyday cycling
• Riding styles that require a wide, stable platform and reliable grip

How to use

Install the Crankbrothers Stamp 1 Gen 2 pedals using the appropriate wrench or pedal tool and correct thread orientation for your crank arms. Position the pedal so the concave face aligns with the sole of your shoe for full contact. Regularly check pin condition and replace any worn pins using replacement pins compatible with the one-piece design. Inspect axle and bearings periodically and service the sealed bearing system according to riding conditions and manufacturer guidance.

Usage recommendations

Choose the pedal size that matches your shoe size for optimal surface area and support. Use the small size for smaller shoe sizes and the large size for larger shoe sizes as indicated by the manufacturer. Clean and dry the pedal after wet rides to prolong bearing and seal life, and tighten or replace traction pins when grip diminishes.
