Cervelo owners with R.A.T. thru axles: This axle will replace the R.A.T. axle found on all Cervelo R.A.T. equipped bikes. In addition to this axle we include our replacement derailleur hanger with with traditional threads. This axle combined with the replacement derailleur hanger will provide a complete threaded thru axle system. Our derailleur hanger matches the geometry and construction of the stock derailleur hanger in every way for crisp shifting performance.
Since 2013, we have been an important part of cyclists’ adventures all over the world. Our axles have millions of miles on them in mountain bikes and road bikes, carbon bikes, fat bikes and e-bikes. Our axles are specifically designed to handle the high-torque loads generated by e-bikes.
Your stock thru-axle is not strong enough to haul your precious cargo! Our axles 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.
Our axles are not just designed in the USA, but are made here as well. They are machined 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.
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.
