Union Carbon Rim - Enduro/Freeride

Union Carbon Rim - Enduro/Freeride

Regular price$349.99

PURPOSE - Enduro

There were 3 main points that went into The Union rim. We wanted a carbon rim that was lighter and had lower radial stiffness than anything we'd made before, and gained a dramatic increase in impact resistance. With our new philosophy on carbon layup design and these key points, we were able to achieve something truly impressive. This rim is made for those who want to race Enduro at a high level and ride harder than ever before. If you have ever had doubts about carbon rims, look no further than The Union.

      Some key tips for building our rims

      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.
