Let me see if I can find the email.... I spoke with D.I.D. who made the wheels for the EVO launch bike. They emailed me the information of the gentleman who custom made the hubs/spokes and then they just laced them to a DirtStar 17-inch wheel. I'll be back....
Alright, D.I.D.'s email gave me the number to Bob Tripp at RAD Mfg., (435)574-2538. I believe this company is the one that designed the hubs on the launch Hypermotard EvoSP.
