Trainer Axle Fit Kit – 12 mm Thru Axle Kit for Bike Shops and Fit Studios

This kit includes three axles and all the spacers and proprietary thru axle adapters need to get any 12mm thru axle equipped road, cross or mountain bike on a trainer.

• Yes, this kit includes our solutions to challenging proprietary axles systems including NAILD and RAT axles.
• These 12mm Trainer Axles are designed to adapt all 12mm thru-axle equipped bikes to your wheel-on trainer. These are compatible with all the popular trainer brands: 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and more.
• The axle is installed with a simple 5 mm hex/allen key.
• Important: Before you order, make sure your specific trainer will accommodate the width of a modern thru-axle equipped bike. All three of these axles measure approximately 200 mm from tip to tip.

Robert Axle Fit Kit contains:

• One 1.0 fine threaded axle, plus spacers, for an axle shaft length of 152 mm to 172 mm and in between. Also includes tapered spacer to match an x-12 axle.
• One 1.5 mm threaded axle, with spacers, for an axle shaft length of 158 mm to 178 mm.
• One 1.75 mm threaded axle, with spacers, for an axle shaft length of 166 mm to 180 mm.
• Three nuts that will replace proprietary systems found on bikes with thru axle made by NAILD and FOCUS RAT.
• 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.
• 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.
• All our products are designed, built and quality tested in the USA. And have been proven around the world.
