Axle Size Help
While installing, if the assembly will not smoothly thread onto your axle, the Axle Release you purchased may not be the same diameter or threading as your axle. DO NOT FORCE the assembly on as this can cause damage to your axle and the Axle Release. Do not return the product until you have visited a local authorized Axle Release Dealer for support.
How do I determine my axle size?
- Measure the diameter of your axle
- Count your threads. This may seem too obvious but it works. Metric threading is measures by threads per millimeter. Example: M10xP1.0, M10 is refering to the diameter of the axle so it is M10 or 10 millimeters. The P1.0 is referring to the thread pitch (or distance between threads). In this case, 1 thread per 1.0 millimeter which is also 25.4 threads per inch if you are metric illiterate. On a non-metric axle such as the most common axle out there-3/8"x26T (3/8" is the axle diameter x 26 threads per inch).
The following are additional axle sizes that are adaptable with the Axle Release system and can be purchased through a local Axle Release dealer:
- M9x1.0- Front "fixie" (fixed gear road bikes) hubs as well as front dynamo hubs (front generator hubs for bicycle head lamps)
- 3/8"x26T - Most axles including most department store bikes; Shimano Nexus and Alfine Series; 8FUN e-bike front hub motors. Very commonly used on road or bikes purchased at department stores that are not fitted with traditional quick release hubs.
- M10x1.0 - European brands, SRAM, NuVinci, Rohloff; Bionx and some e-bike front hub motors
- 3/8"x24T - Rear coaster brake hubs found commonly on beach cruisers, Huffy brand, older department store bicycles
