Alpha Disc Guard

  • Sale
  • Regular price $45.00

The Martine was a refined guard. Light, strong, classy. Well that refinement has gotten even simpler by shearing the aluminum mount. Now you can have all of the protection of the Martine, but for less! But affordability and lightness aren't the only positives of the Alpha Disc Guard. The supplied insert that is included with the guard allows for quick-release and standard axles. Now you can have a axle-mounted guard no matter your axle type (excepting you thru-axle weirdos). So iron your printed tuxedo shirt, clasp your clip-on and hang out with the fancy folk with the Alpha Disc Guard.
