🚵 Mountain Bike Pedals – Frequently Asked Questions

What type of pedals are best for mountain biking?

  • What size mountain bike pedals do I need? Most adult mountain bikes use 9/16″ pedals.
  • Is it OK to use MTB pedals on a road bike? Yes, but road-specific pedals may offer better power transfer.
  • Is it harder to pedal a mountain bike? Yes, due to terrain, weight, and tire resistance.
  • Are all MTB pedals universal? Most are, but check the thread size (usually 9/16″).
  • How do you pedal efficiently? Maintain a smooth cadence and consider clipless pedals.
  • What are SPD pedals? SPD (Shimano Pedaling Dynamics) are two-bolt clipless pedals for MTB use.
  • Difference between SPD and Time ATAC? Time ATAC offers better float and mud clearance; SPD is more widely supported.
  • Flat or clipless for gravel bikes? Both work—flats offer freedom, clipless offer control.
  • How do I tell if my pedals are ½” or 9/16”? Measure the spindle or check your crank arm specs.
  • What pedals do downhill riders use? Large platform flat pedals or DH-specific clipless systems.
  • Road vs MTB pedals? Road pedals prioritize power; MTB pedals are more rugged and walkable.
  • When to use flat pedals? Great for beginners, technical trails, or freeride terrain.

Are all mountain bike pedals 9/16?

  • How do I tell if my pedals are ½” or 9/16”? Measure the diameter or consult your bike’s specs.
  • What does 9/16 mean on pedals? It’s the thread diameter, standard for most adult bikes.
  • What size pedals fit 3-piece cranks? Typically 9/16″.
  • Are all MTB pedals universal? Most are, but always check compatibility.
  • What size bike should I get if I’m 5’9”? Likely a medium (17–18″), but consult a sizing chart.
  • Best pedals for MTB? Depends—consider Shimano SPD, Crankbrothers, or OneUp flats.
  • Difference between 9-speed and 12-speed MTB? Gear range and shifting—no direct pedal impact.
  • What are the two sizes of bike pedals? 9/16″ and 1/2″.

Should I use clipless pedals for mountain biking?

  • Disadvantage of clipless pedals? Learning curve and risk of falling while learning.
  • OK to use MTB pedals on road bike? Yes, they’re often used by commuters and gravel riders.
  • How do you avoid falling with clipless? Practice unclipping early before stops.
  • Do downhill riders use clipless? Some do for control; others stick to flat pedals for quick release.
  • How to install clipless pedals? Thread pedals in carefully; left side is reverse-threaded.
  • Are magnetic pedals any good? Novel but not widely adopted; limited security.
  • Flat or clipless for gravel? Depends—flats = freedom; clipless = long-ride efficiency.
  • Best pedal for MTB? Depends on your riding style. See our MTB pedal guide.
  • Road vs MTB clipless? Road: bigger cleats, more power. MTB: smaller, dual-sided, easier to walk.
  • Do pros use clipless? Yes, nearly all XC and enduro racers do.
  • Benefits of SPD? Secure fit, consistent pedaling, improved climbing power.

Are all mountain bike pedals the same?

  • How do I know what pedals fit? Confirm crank threading—9/16” is the standard.
  • Are all MTB pedals universal? Generally yes, but confirm before purchase.
  • Are MTB cranks universal? No—standards vary by brand and drivetrain.
  • Pedal thread sizes? Mostly 9/16”; some older or kids’ bikes use 1/2”.
  • What are the three pedal types? Flat, clipless, and cage/strap.
  • SPD vs SPD-SL? SPD = MTB/two-bolt. SPD-SL = road/three-bolt.
  • Downhill pedal choice? Often flats with metal pins for max grip.
  • How to pick MTB pedals? Consider your skill level, terrain, and riding goals.
  • Best flat pedal for MTB? OneUp, DMR Vault, Race Face Chester are solid picks.
  • Are clipless better than flats? For performance—yes. For learning or tech terrain—flats shine.
  • SPD vs Time ATAC? ATAC = better float and mud clearing; SPD = common and reliable.
