Make sure your shoes match
- 2-bolt shoes take SPD cleats (and other 2-bolt systems).
- 3-bolt shoes take SPD-SL, Look Keo and similar road cleats.
- Some road shoes take both, using an adaptor plate.
Cleat float
Float is how far your heel can turn before the cleat releases. A little float is kinder on your knees.
| SPD-SL cleat | Float |
|---|---|
| Yellow | 6° (most popular) |
| Blue | 2° |
| Red | 0° (fixed) |
SPD cleats come as SH51 (single release, twist out sideways) or SH56 (multi-release, easier to get out of, good for beginners).
Setting up
- Line up the ball of your foot just in front of the pedal axle.
- Set the angle so your foot points the way it naturally does.
- Start with low spring tension and practise clipping out while standing still, holding something.
FAQs
Are clipless pedals safe for beginners?
Yes, with practice. Start with SPD and multi-release cleats.
How often should I replace cleats?
When they're worn or release unexpectedly. Road cleats wear faster if you walk on them.
Can I use flat shoes on clipless pedals?
Not well. Dual-sided pedals with one flat side are an option.
