This thru axle is used to attach trailers to Orbea mountain bikes with a 1.25mm thread pitch thru axle. Robert Axle Project Thru Axles for Kid Trailers are designed specifically to fit your 12mm thru-axle bike and allow attachment of any two-wheeled, hitch-mounted trailer, such as Thule, Chariot, Burley, Instep, Carry Freedom and more. This axle replaces your stock axle that came with your bike.
This thru axle is for attaching a child or cargo trailer with a standard “hitch-style” attachment to the center of the wheel. Since 2013, we have been an important part of cyclists’ adventures all over the world. Our thru axles have millions of miles on them on mountain bikes and road bikes, gravel and cross bikes, fat bikes and e-bikes.
Your stock thru-axle is not designed to haul your precious cargo – your kids, your pet or your gear! Robert Axle Project thru axles are specifically designed to handle the heavier load of a trailer behind your bike, and are 3 to 4 times stronger than the stock axle that came with your bike. Our stainless steel axle ends provide a safe and secure attachment point of the hitch to the axle. The axle is quick to install and remove with a common 5mm hex key, allowing ease for repairs or removal.
Our axles are designed, machined and tested in the USA, by avid cyclists, to the tightest standards in the industry. We safety test, to failure, every batch of axles we produce to ensure they exceed your expectations and safety.
Robert Axle for Kid Trailers replaces your stock thru-axle so you can attach a child or cargo trailer to your 12 mm thru axle equipped bike.
