Yes, you can now attach your 12mm thru-axle equipped bike to an indoor bike trainer. Simply use our Fitment Finder to find the Robert Axle that fits your bike. Remove your stock thru axle that came with your bike, replace it with a Robert Axle, and attach your bike to the trainer. The Robert Axle Project is happy to be one part of your bike training.

Year Round Cycling

Let’s face it; most of us don’t have the time to ride outside every day. And a good portion of us live somewhere with a real winter—like the type of winter with snowmen and icicles. Cold temps and short days make for tough training on the bike. And whether you like it or not, getting on the indoor trainer is a great way to train for the cycling season. Even riders in sunny climates can benefit from an indoor spin every now and again.

Replacement Bolt-On Axles

Are you looking to replace that big bulky handle on the 12 mm thru-axle that came with your bike? Are you a Clydesdale that has bent or broken your stock thru-axle?

Our Bolt-On replacement thru-axle offers a lower profile design with greater strength and durability. These axles made of the same materials and construction as our axles that are used with heavily loaded cargo trailers.
