The Trainer Axle is engineered to seamlessly connect your bike with a thru axle to a wide range of wheel-on trainers, including 1up, Blackburn, Cyclops, Kinetic, Tacx, and Wahoo. It is precision-crafted to fit your bike’s thru axle exactly, reducing the need for spacers and additional components. This results in a streamlined, high-performance axle that ensures efficient training, effective warm-ups, and peak readiness for racing seasons.
Important: Prior to purchasing, verify that your trainer can accommodate the width of your modern thru-axle bike. Measure the trainer at its widest position and compare it to the outside width of your bike frame. Note that the trainer axle ends will protrude beyond the frame on both sides.
KEY FEATURES
Robert Axle for Trainers replaces your stock 12 mm thru axle so you can use your bike on a trainer.
This axle is compatible with 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other wheel-on resistance trainers.
The true length of the axle shaft is 172 mm, but can be shortened using the included spacers – a flat spacer and a tapered X-12 spacer. This allows for axle lengths of 162, 167 or 172 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 1.0 mm thread pitch.
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 5 mm hex wrench.
Designed, built and quality tested in the USA. Proven around the world.
