Established in 2012, derby rims began because Ray, also known as "derby", bought some carbon fiber rims for his trail bike. But he he was very disappointed in the loss in stability and cornering traction compared to the 35mm wide aluminum rims he had been riding. derby  liked the much lighter carbon rims for climbing and improved ground tracking from less un-sprung wheel weight . So derby  began to design WIDE  rims to be made in carbon fiber. And a business was born.
