⚡ At a Glance
- • Strength-to-weight: 6061 T6 aluminium construction for a high strength-to-mass ratio
- • Best for: Riders with 12 mm forks and hubs seeking lighter, secure axles
- • Not ideal for: Frames or hubs requiring non-M12 threads or different diameters
CNC-machined 12 mm thru-axles made from AA standard 6061 T6 aluminium. Available in several overall lengths with M12 nut compatibility and a 1.75 mm thread pitch.
Secure wheel retention – With M12 nut and 1.75 mm thread pitch
The M12 nut combined with a 1.75 mm thread pitch gives multiple full-thread engagements, with a 20 mm thread length specified. After subtracting thread length, installation length is 172 mm for the 192 mm axle.
Consistent clamping across forks and hubs reduces axle slip and play, improving safety and confidence under load.
Lightweight performance – Thanks to 6061 T6 aluminium and CNC machining
Axles are formed from AA standard 6061 T6 aluminium and finished by precision CNC machining to control wall thickness and overall mass. The listed item weight is 44 grams.
Lower rotating mass helps acceleration and handling while retaining alloy strength for everyday riding demands.
Easier fitment across builds – With multiple length options available
Sizes offered include 122 mm, 166 mm, 171 mm, 175 mm, 180 mm and 192 mm overall lengths, enabling selection for different forks and rear hub spacings. The defined thread and installation lengths simplify measuring for correct fit.
Matching axle length to frame and hub spacing is straightforward, reducing the need for adaptors or specialist parts.
