Look vs Shimano SPD-SL clipless pedals: which to choose in 2026?

The match of two references

On the road, two clipless pedal standards share 90% of the market: Look Keo and Shimano SPD-SL. Both have their fans and their limits. Here's an honest comparison after 8 years working on both systems.

Look Keo: the historic choice

• Wide flat cleat (60mm), good pedal-stroke stability
• Adjustable tension on Keo 2 Max and up
• 3 cleat hardnesses: grey (9°), black (0°), red (4.5°)
• Weight: ~125g/pair for the Keo Blade Carbon Ti

The grey cleat (9° float) is the most forgiving on the market — ideal for sensitive knees. Large contact surface = gentle pressure distribution.

Downside: the cleat wears fast if you walk on it. Expect 6 months for regular use without walking covers.

Shimano SPD-SL: precision

• Similar flat cleat (52mm) with sharper geometry
• 2 hardnesses: yellow (6°), red (0°), blue (2°)
• Allen 3mm screw-adjustable tension mechanism
• Weight: ~115g/pair for the Dura-Ace 9100

Strong point: tension mechanism longevity. An R8000 pair easily lasts 30,000 km without service.

Weak point: the engagement click is sharper than with Look. Takes 2-3 rides to adjust.
