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 BKool, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other on-wheel resistance trainers.
The true length of the axle shaft is 188 mm. However it can be used with the included spacers at 176mm or 169mm,
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 12×148 hub does not equal a 148 mm long axle.
This axle has a 1.25 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 5mm hex wrench.
