What are the differences between SPD and SPD-SL pedals, and which one would be more suitable for my cycling needs?

SPD pedals are typically used for Mountain Biking and casual cycling, offering a recessed cleat for easier walking. SPD-SL pedals are designed for road cycling, providing a larger cleat for better power transfer. If you prioritize walking comfort and versatility, choose SPD pedals. For maximum power efficiency and performance on road rides, opt for SPD-SL pedals.
