Complete Guide to Cycling Shoes and Pedal Systems: How to Choose Between SPD-SL, Look, and Speedplay

Why Do You Need Clipless Pedals?

Using a clipless pedal system (cycling shoes + clipless pedals) is an important step in progressing from a recreational rider to a serious cyclist. The benefits of clipless pedals include:

• Improved pedaling efficiency: You can apply power on both the upstroke and the downstroke
• Stable pedaling motion: Your feet won’t slide around on the pedals
• Better power transfer: The perfect connection between stiff soles and the pedals
• Riding confidence: Your feet won’t come off on rough terrain

Comparison of the Three Major Road Clipless Pedal Systems

Shimano SPD-SL

Who It’s For

• All riders, from beginner to professional
• Riders who prefer a stable, large-platform pedaling feel

Cleat Types

• Red (SM-SH10): 0° float, pure racing use
• Blue (SM-SH12): 2° float, for advanced riders
• Yellow (SM-SH11): 6° float, top recommendation for beginners

Pros

• Highest market share, replacement parts are easy to find
• Stable and solid pedaling platform
• Excellent weight savings at the DURA-ACE level

Cons

• Single-sided entry only
• Cleats wear out faster (recommended replacement every 3-6 months)

Look Kéo

Who It’s For

• Riders with sensitive knees (large float angle)
• Riders seeking weight savings

Pros

• Smooth clipping in and out
• Kéo Blade Carbon is extremely lightweight
• Wider selection of float angles

Cons

• Cleats protrude more, making walking inconvenient
• Some shoe models have incompatible hole patterns

Wahoo Speedplay

Who It’s For

• Riders seeking the convenience of dual-sided entry
• Riders who need precise float angle adjustment
• Triathletes

Pros

• Dual-sided entry: You can clip in without looking
• Stepless float angle adjustment
• Lowest stack height (smallest Q-Factor)

Cons

• Requires dedicated cleat covers (otherwise walking will damage them)
• Higher price
• More troublesome to clean and maintain

Cycling Shoe Buying Considerations

1. Sole stiffness: Carbon fiber sole > nylon sole (carbon fiber offers better power transfer)
2. Last width: Asian feet tend to be wider, so pay attention to wide-last options
3. Ventilation: Taiwan’s climate is humid, so breathability is important
4. BOA dials vs. Velcro: BOA offers more precise adjustment
5. Hole pattern compatibility: Confirm the shoe’s hole pattern is compatible with your pedal system

Beginner’s Guide to Going Clipless

Week 1:

• Practice clipping in and out on grass or soft ground
• Set the release tension to the loosest setting
• Practice unclipping early before stopping at red lights

Week 2:

• Short, flat practice rides
• Learn to unclip and stop on one foot
• Get familiar with the ankle-outward rotation motion for unclipping

Week 3 and beyond:

• Gradually increase riding distance
• Start attempting climbs and descents
• Moderately tighten the release tension

Frequently Asked Questions

• What if I crash: Zero-speed falls from “forgetting to unclip” are normal for beginners—don’t get discouraged
• Knee pain: It may be due to incorrect cleat angle; a Bike Fitting is recommended
• Inconvenient for walking: You can use cleat covers
