Purpose built to adapt your thru axle equipped bike with your wheel-on trainer, such as a 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other trainers. The goal is to fit the thru axle to your bike perfectly, so to minimize spacers and extra parts, providing a clean, high performance axle for your bike. Train, warm up and be race ready and fit for the season.

  • This rear thru axle is specific for using your Mavic Speed Release bike on a wheel-on trainer. The thread, a “double lead-in” thread, is proprietary to the Mavic Speed Release system only.
  • Weight: 0.3125 lbs
  • This axle is compatible with BKool, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other on-wheel resistance trainers.
  • The true length of the axle shaft is 165 mm. Please note: Thru-axle lengths do not equal hub standards. An axle has to be longer than the hub to fit in the frame. A 12×142 hub does not equal a 142 mm long axle.
  • This axle has a proprietary “double lead-in” thread found only on Mavic Speed Release bikes.
  • The axle shaft and axle ends are precision CNC machined from 7075 aluminum, and hard anodized for rugged durability.
  • No special tools required. Design allows for installation or wheel removal using your standard 5mm hex wrench.
  • Designed, built and quality tested in the USA. Proven around the world

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.
