Details
There were 3 main points that went into The Union. We wanted a rim that was lighter than The Agent, had lower radial stiffness than anything we'd made before, and gained a dramatic increase in impact resistance. With our new philosophy on 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.
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.
