The Union is a do-it-all carbon wheel, designed to shred anything that’s thrown at it.

We took a three pronged approach to the creation of the Union; create a carbon rim that’s lightweight, has low radial stiffness and has extremely high impact resistance. Combining these three points with our unique layup design, we were able to achieve a truly impressive “quiver killing” rim. The Union’s design makes it the perfect choice to race enduro at high levels, shred the local trails on an afternoon ride or smash a solid day of shuttle laps.

Available in 27.5" and 29er Diameters

The tires we recommend are a range from 2.35 - 2.8

  • 485g for the 27.5

  • 495g for the 29er

  • 600mm for the 29er, 2mm offset

  • 561mm for the 27.5, 2mm offset

Spoke Tension Meter

We always require that you build with a high-end tension gauge. Make sure that the tension meter is calibrated and reading correctly. 

Our high tension target is 115kg/f. Do your best to keep all tension within 2% from one spoke to the next on each side of the hub. If you can achieve better, the better the wheel will be, and the longer it will go without needing maintenance.

DO NOT build our wheels without a tension meter. It will lead to premature failure and undue stress on the rim.

Sapim Polyax Secure Lock Nipples

All of our rims must be assembled with Sapim spokes and nipples. Sapim makes by far the best nipple in the industry, and we do not rely on anyone else in-house. 

The shape of the Polyax nipple is ideal for building without washers and provides the best possible nipple to spoke articulation to date. 

If you cannot use or find the Polyax nipples, let us know, and we can sell you some and ship them with your rim order.

Pro Level Truing Stand

Using high-quality tools always gives the best outcome. If you have taken on the job of building up your wheel, please ensure you have the required tools to do so. 

A professional Parktool truing stand, lateral dishing tool, and high quality 4 sided spoke keys are an excellent place to start. 

Take your time and enjoy the process. Building wheels can be very rewarding and the outcome, if done right, can last a lifetime. 

You got this!
