Why We Like The Atlas Cinch Crank Arms

When it comes to aluminum cranksets, few can rival the brute strength and total reliability of the Race Face Atlas Cranks. We've run these things on everything from trail bikes to full-on downhill rigs, and after countless rock strikes and season upon season of use they're still going strong. They aren't the lightest option out there, but they are tough, and they come in some sharp-looking anodized colors to spice up your rig.

  • Burly aluminum crank arms for trail, enduro, and gravity riding
  • Forged 7050 alloy is uber stiff and incredibly strong
  • Universal compatibility with any MTB and any drivetrain
  • Includes Cinch 30mm spindle
  • Cinch chainring and cinch bottom bracket sold separately

What do you think about this product?



Will this fit a 92mm bottom bracket


Do they come with the spindle?


Does this crankset come with the spindle? Also, is this the 68/73 BB shell spindle? Finally why is your price for this crankset so expensive? Every other online MTB store and the RACE FACE website has this exact crankset in any size and color for $178.50!!!! Can you do a price match for me? If you can price match I’ll get a set but if not I’ll get it off the Race Face website...


Does this come with the spider?

Hey dave, it does not. It is for direct mount chain rings, like this one:
