The Ashima Airotor 410 six-bolt disc brake rotor is targeted at the serious weight weenie and is the lightest on the market. It is ideal for the cross country rider looking to shave every possible gram for race day.Super light and ultra durable, this 41 stainless steel rotor weighs in at only 68 grams for the 140mm.

The AirRotor design is unique to Ashima and has been double ground for superior flatness. It has excellent performance and heat dissipation in both wet and dry weather.

They're ideal to reduce rotating weight on kids bikes, providing strong braking for Cyclocross, Road, Triathlon & MTB XC. They are not intended for Downhill use.

Some said AiRoTor would never work….then 3 years and several World Championships later. This is AiRoTor technology taken to the limit!

  • 1 Super Lightweight rotor
  • Excellent Heat Dissipation
  • Fully Tested
  • High grade SUS410 stainless steel
  • Unique Ashima design 
  • Excellent wet/dry performance 
  • Excellent heat dissipation 
  • Rapid air circulation
  • Use: MTB Cross Country, Road, Triathlon, Cyclocross
  • Diameter: 140mm
  • Fixing: Standard 6-hole (IS2000)

Caution: Due to extreme low mass AiRotors heat-up more than heavier rotors which may adversely impact some lower spec systems during prolonged braking events. However, conversely due to the extreme low mass they also cool very fast, so with proper/normal braking consideration the heating/cooling effect can be balanced.

Best socks ever
Size: Large, Color: (100) White / White / Mod Gray
Best athletic socks I’ve bought. I usually buy UA socks anyway and these are the best. Super soft and comfy. Fit snug and my feet don’t slide around in them.

Much much better than the standard sock
Size: X-Large, Color: (001) Black / Black / Castlerock
These socks are superb. Lots of padding in the right places, snug where it should be snug & loose where you don't want it to bind. They are marked with an 'L' for left foot, & 'R' for the right foot (it makes a difference in the fit being perfect. They stay up on your heel & don't slide down

4 lefts vs 2 rights
Size: Medium, Color: (001) Black / Black / Castlerock, Size: Medium, Color: (001) Black / Black / Castlerock
I ordered a set of three. I ended up with four left socks and two right socks lol. Granted it doesn’t matter unless you’re OCD. JEEZ. Love the socks but not the attention to detail the sock company did on matching left/right marked socks.

Hold up to tough wear - definitely recommend
Size: X-Large, Color: (001) Black / Black / Castlerock
These are my teens favorite socks. We've ordered multiple sets. Given that he tends to wear then as slippers I am really impressed with how they hold up. The extra large size is great for bigger feet. They wash well and I didn't notice any shrinkage, fading or pilling. This set is going to college with him.
