Please note: When selecting the correct axle for your bike there is a handy Thru Axle Finder so you can easily find the exact axle you need. This can be found by scrolling down the page to the downloads section or by visiting the Robert Axle brand page on our website. If you are still unsure then please contact us before purchase.

With the Robert Axle Thru Axle for Trainers, you no longer need a second bike for indoor training or warming up for a race. The Trainer Thru Axles are available for road, cross, gravel or mountain bikes & can be used on or off the trainer. Machined & tested in the USA, the Trainer Thru Axles are designed for maximum strength & ease of use.

- A trainer thru axle specifically built to fit your bike first, rather than a “one-size-fits-most” adapter.
- Primary focus is to build a precision thru-axle. RAP say that their axles fit the specific bike as well or better than the stock axle.
- Suitable for on or off the trainer. Indoors or out. Ride/Train more, with less time wrenching.
- No special tools required. Installed or removed using standard 5mm hex key found on your multi-tool.
- Designed, built & quality tested in the USA.

- The true length of this axle shaft is 165mm long. This axle comes with a 6mm flat spacer. So this axle can be 165 or 159mm long depending if the spacer is used.
- Thread Pitch: 1.5mm
- Important: Make sure the trainer will accept the additional width of a thru-axle equipped bike. The total width of this axle is: 195mm.

Prosamazing build quality
Stumbled across this thru axle adapter after being let down by Tacx/Garmin! Just wish I had found it 5 weeks earlier so that I can use my road bike (Orange R9) on my turbo trainer.
Easy to fit and the build quality looks A*, thanks

ConsIt is expensive for what it is. I’m guessing it’s due to being manufactured in the US.
ProsWell made precision axle
I bought this as for some strange reason Kinetic have stopped supplying their Thruaxles, utter bonkers. Anyway I found this as an alternative and it is just the ticket. Quality through axle which fitted perfectly on my Giant Defy.
Brilliant axle!

ProsWell made and finished axle. Allows me to use an older turbo with a disc brake bike
I can now use my disc brake Ridley Noah Fast bike with my ageing (but still performing well) Racermate Computrainer turbo.

I needed the Robert Axle Project Turbo Trainer 12mm Thru-Axle - M12 x 1.5 - 159/165mm, with the supplied chunky spacer washer installed on the non-drive side.
The fit to get the axle ends inside the frame is a little tighter than with a Quick Release, but perfectly doable without any modifications needed.
The result is the bike is held securely.

It's a nicely finished axle too, it exudes good quality and craftsmanship.
Exactly what I needed and the best I found

ProsLooks great, precision engineered , value for money
I love innovation and this product has been well thought out and engineered to meet the needs of people with disc break wheels that want to use turbo trainers. The Robert axle doubles as a standard thru axle and with the additional end fitting it is ready for ref turbo

Will the TRA212 work with a Wahoo Kickr Snap
16 Feb 2021

The TRA212 according to the axle finder is correct for my 2020 Orbea Orca Aero Disc which I am happy with.

Would this axle work with the wahoo kickr snap please?

Thank You
Thank you for your enquiry, yes this will fit fine.

Do i need the TRA212 or TRA204
19 Jan 2018
My axle is on a 2018 WHYTE WESSEX ONE 12mm dia 167mm long with a 1.5mm thread . The TRA212 is 2mm short the TRA204 is 5mm long ? . Your help would be greatly appreciated .
Hi there,

The best option will be to use the longer axle and use a spacer to take up the difference of 5mm.
