Product Description
Our Rear Hub Axle Replacement Kits make switching or updating your hub’s spacing a breeze. They are designed to be installed and removed without the use of any special tools so there is no hassle involved and the process is quite simple. All of our axles kits include the axle itself, end caps, spacers (if necessary), and a tension nut. Be sure to check our Axle Compatibility Chart to verify that the axle you are purchasing is compatible with your hub as they are not all universal.
Rigid Quality Control. This is something we take VERY seriously. You will not receive a part with a scratch or ding. We believe it is your job to try and tear this baby up, not ours. We also maintain tight controls on anodizing to provide consistent colors and use an extra long seal to preserve color. Unfortunately, fading is part of the nature of the anodizing process, but the extra long seal helps maintain the original brilliance as long as possible.
Outstanding Customer Service. We pride ourselves on our knowledge and our availability. A real person still answers the phone and we have team of knowledgeable sales and technical advisers available to help you over the phone or via email. Our response times are normally very fast, often same day and our shipping team works hard to get your product as quickly as possible (often same day).

Can I purchase the 148x12 axle or the 150/157x12 axles and put them on a G2 hub to run it on a different frame? No. The Boost and DH axles will not work with a G2 hub. For those spacing to work you would need to order a Boost rear hub or a DH hub.
+
How do I know what hub I have so I can make sure to get the correct axle? One way to see if you have a G1 or G2 hub is to check the color of the freehub body. G1 has a Silver freehub body and G2 has a Black freehub body. Another way to tell is to measure the hub. Here is a link to our hub dimensions chart.
