Race Face

Frequently Asked Questions

• How do I choose the correct spindle diameter and spindle length for Race Face cranks?

  Check your bike’s bottom bracket spec first: Race Face cranks come with 24mm spindles (common on Aeffect and many Trail cranks) or 30mm spindles (used on Era, Turbine, Atlas, SixC). For 24mm spindles a 137mm length is typical and yields roughly a 51–52mm chainline for modern trail setups, while DH/Boost bikes may use longer spindles (e.g., 151mm) to achieve a wider chainline—match spindle diameter and length to your BB shell and chainline requirement.
• What crank arm length and model should I pick for trail, enduro, or XC riding?

  For trail and all‑mountain riding the Aeffect crankset is a durable 6066‑aluminum option available in 165mm, 170mm, and 175mm arm lengths (652g reported for the 170mm with a 32T ring), while the Era crankset provides a carbon option that spans XC to gravity applications with gravity‑grade strength. Choose shorter arms (165–170mm) for quicker clearance and faster cadence on technical terrain, and longer arms (170–175mm) if you want more leverage for climbing or bigger riders; prioritize intended activity and your preferred cadence/clearance.
• Are Era wheels suitable for e‑MTBs and what are the key specs I should know?

  Era Wheelset is built for trail and enduro use and is approved for lightweight e‑MTBs up to 65 Nm of motor torque but is not intended for full‑power e‑MTB applications. The Era rims are carbon, tubeless‑ready with low‑profile double‑wall construction and Vault hubs (60T engagement, 120 points of engagement), come in 27.5" or 29" options, and support Boost/Super Boost spacing with XD or MicroSpline freehub bodies depending on spec.
• What should I know about setting up Era wheels (tubeless, hub maintenance, and rotor mounting)?

  Era rims are tubeless‑ready and are shipped tubeless‑taped and valved so you can mount tires with sealant for a standard tubeless setup; use a compatible tubeless tire and an appropriate amount of sealant for your riding conditions. The Vault hubs use a 60‑tooth ratchet for 120 points of engagement and require periodic bearing and seal inspection—Era hubs support XD or MicroSpline freehubs and 6‑bolt rotors (Centerlock versions have been introduced on some builds), so confirm freehub/rotor compatibility with your drivetrain and brake mounting.
