    Performance by design

    The Difference is in the Details

    At RF, we're obsessed with the belief that the "whole" should be greater than the sum of its parts.  It's why we build our wheels in-house, by hand.  It's also what leads us to design and manufacture almost all of the components that we use to build our complete wheels.  From hubs & rims, to tubeless tape & valves, we design each and every part to work together flawlessly as well as to excel individually.

    I can't believe how much I've enjoyed these Livewire wheels...I'm glad I was introduced to this small, SoCal company because these cross-country wheels have been a revelation to me!  MTBR.com Gear of the Year

    We have to give it to RideFast for building such top quality equipment.  If trusty and durable carbon wheels are on your wish list, check out the Hotlines.  MBA Field Test
