Crankbrothers Stamp Flat MTB Pedals - Lightweight, Durable Grip

In this review of the Crankbrothers Stamp Flat MTB Pedals the bottom line is straightforward: these are a lightweight, serviceable flat pedal built for riders who want a slim profile and reliable grip without sacrificing durability. The pedals pair a forged 6061-T6 aluminum body with a concave platform and ten adjustable pins per side to hold shoes firmly in place, and they come in two sizes so riders can match pedal platform to shoe size. For trail and all-mountain riders who value traction and low weight, these pedals deliver.

Key Features

• Forged aluminum body: The 6061-T6 aluminum construction keeps the pedals light while maintaining a premium feel and resistance to pedal strikes.
• Thin profile platform: The minimal 11-13mm thickness reduces catch and keeps center of gravity low for more confident cornering and control.
• Concave surface and pins: The concave platform with a 10 hex pin pattern per side provides consistent, adjustable traction with most flat-soled MTB shoes.
• Serviceable bearings and spindle: Igus bearings, an external seal, chromoly spindle and a grease port make routine maintenance simple and extend service life.
• Size-specific fit: Stamp Small and Stamp Large are sized to match shoe ranges so riders can pick the platform that best complements their foot size and stance.
• Long coverage: A five year warranty and available refresh kit mean these pedals are intended to be maintained and kept in service for years.

Who It's For

These pedals are aimed at trail, enduro and all-mountain riders who prefer flat pedals and want a lightweight, durable platform that offers predictable grip with a variety of shoes. The two size options make them a good match for riders with smaller feet who want a compact platform or larger-footed riders needing more surface area.

Riders who want inexpensive plastic flats or those who never plan to service components might look elsewhere, since these pedals are optimized for riders who care about weight, serviceability and a premium metal build rather than disposable platforms.

Pros & Cons

Pros

• Excellent grip from the concave platform and adjustable pins that hold shoes securely.
• Lightweight for a metal flat pedal, with 345g per pair for Small and 375g per pair for Large.
• Durable, serviceable design with quality Igus bearings, external seal and grease port for maintenance.
• Two size options to match shoe ranges for a better shoe/pedal interface.

Cons

• Metal pins and thin platform may feel firm under softer shoes and can wear shoe soles faster than some plastic pedals.
• Riders who want a completely maintenance-free, low-cost pedal may prefer a composite option instead.
