What's the difference between SPD and SPD-SL?
SPD (Shimano Pedaling Dynamics) is a 2-bolt cleat system with a small recessed cleat used in mountain biking, gravel, and commuting. SPD-SL is a 3-bolt road system with a large exposed cleat. They are completely incompatible—SPD cleats won't fit SPD-SL pedals and vice versa. For mountain biking, you want SPD (or compatible 2-bolt systems like crankbrothers or Time ATAC).
Read answer →02Should beginners start with clipless or flat pedals?
Most coaches recommend starting mountain biking with flat pedals to develop fundamental bike handling skills—weight distribution, cornering technique, and the ability to quickly dab a foot. Once these basics are solid (typically 3-6 months of regular riding), transitioning to clipless adds efficiency and security. Starting clipless too early can create dependency and slow skill development. There's no shame in riding flats, and many expert riders still prefer them for certain disciplines.
Read answer →03How tight should MTB clipless shoes fit?
MTB clipless shoes should fit snugly without pressure points. You should be able to wiggle your toes slightly, and there should be no heel lift when you walk or simulate an upstroke. The shoe should feel like a firm handshake around your foot—not crushing, but with no slop. Remember that feet swell during riding, so a shoe that feels perfect at minute zero should have a tiny bit of room for expansion. If you feel numbness or hot spots within the first hour, the shoe is too tight or too narrow.

Yes, you can use MTB clipless shoes with SPD pedals on a road bike. Many recreational road riders and bikepackers do exactly this for the walkability benefit. The trade-off is slightly less power transfer than road shoes with 3-bolt cleats. If you're not racing or doing high-intensity group rides, the convenience of walkable shoes often outweighs the marginal power loss. Some riders use SPD pedals on their road bike specifically to share one shoe across multiple bikes.
Read answer →05How do I know when to replace my cleats?
Replace your cleats when you notice any of these signs: difficulty engaging the pedal (have to stomp multiple times), unexpected releases during hard pedaling, excessive lateral play/wobble when clipped in, or visible wear on the cleat engagement surfaces. For most riders, cleats last 6-12 months. Walk more frequently and they wear faster. Brass cleats (standard SPD) wear faster than steel but offer better mud shedding. Always carry a spare cleat and the mounting bolts.
Read answer →06What's the best cleat position for mountain biking?
Start with the cleat positioned so the ball of your foot (first metatarsal head) is directly over or slightly behind the pedal axle. This is the standard starting point. From there, small adjustments based on comfort: move the cleat forward if you experience calf cramps, or back if you want more stability and less calf engagement on long climbs. Angle the cleat so your heel doesn't hit the chainstay or crank arm. Most riders find their ideal position within 2-3mm of the starting point. If you have knee pain, consult a bike fitter—cleat angle and fore/aft position significantly affect knee tracking.
