TECHNICAL DATA

Great wheel builders have long held a reputation as masters of the dark arts. We have delved into the minds of some of the best builders we could find, helping us to establish a set of rules on how we construct the best wheels we possibly can. It's one thing to make great parts.Taking these and making a great wheel is another matter altogether.

The data below is aimed at our wheel builders who are using our rims to create quality custom wheelsets for their customers.

If there are any questions at all about this information please don't hesitate to use the chat or email us.
