12mm Thru Axle for Resistance Trainer and FOCUS R.A.T. – 12×142 or Boost
$ 64.00
Our Trainer Axle is designed to adapt your thru axle equipped bike with your wheel-on trainer, such as a 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other trainers. Our goal is to fit the thru axle to your bike perfectly, so we minimize spacers and extra parts, providing a clean, high performance axle for your bike. Train, warm up and be race ready and fit for the season.
An additional benefit you will experience, once you switch to our threaded trainer axle, when riding outside with this axle your disc brake will no longer rub. This is due to the more consistent and greater clamping force of a threaded thru axle vs the RAT system. Consider our Lightning Bolt-on Front axle to rid your bike of the flex from the R.A.T.
This axle is specific to bikes with FOCUS R.A.T. thru axles and 12×142 or Boost hub spacing. Includes a replacement R.A.T. nut with the Trainer Axle.
Description

Great for the rear Wheel
Easy to work with when getting a flat
The R.A.T. Was hard to get all the way in,especially with a heavy Wheel
Rat is great for the front one
Very happy with the Robert Axle unit ??

If you have a Focus bicycle With R.A.T. Axels and want to use your bike on a trainer, this is the axel to use! Meticulous design and works flawlessly. I am using mine with a Wahoo Kicker trainer.
It works so well that I will be upgrading my existing axels on my bike to for riding and racing (different axels), but based on my experience with this trainer axel it is a no brainer. Thanks again for a great product that is far superior then the oem R.A.T. Axels.

So far so good. Bought to put my Focus Mares on the trainer. I’ve rode it on the road but I really don’t pay attention to how it felt before or after but it does work great on trainer. Too bad I moved to an area where I predominately use this bike on trainer now. Miss my trail riding. Ugh.
Anders (verified owner) –
Nothing bad to say about this axle. Works like a treat, easy installation and great build quality.
I will use this one for indoors and outdoors.
Only wish were to have it in black but maybe the colour would come off on the trainer anyway, but no big deal.
Got the front axle too!

So happy to have found this when I understood that my Focus Mares needed an adapter for the trainer I bought. Good and simple instruction – worked like a charm
DIEGO García (verified owner) –
