Why We Build It

Hotwires are designed as a pure cross-country raceday wheelset, that is strong and reliable enough to ride everyday. 

Hotwires are featherweight climbing wheels that provide outstanding acceleration through torsional stiffness.

Vertical ride compliance and torsional stiffness is improved by the use of SPM™ straight-pull hubs and 28 Sapim CX Ray semi-areo spokes per wheel, laced three-cross (while straight-pull hubs from many other hub makers count the spoke lobe as one of the cross points, SPM™ hubs are truly 3x, maximizing torsional strength).  Snappy under power while offering vertical compliance to compliment the efficiency and improve the ride quality of hardtail and short travel XC race bikes. 

The 25mm internal width of the Hotwire is ideal for tires up to 2.25".  

More aggressive riders, and/or riders seeking additional cornering support and improved tracking in rough conditions should check out our 30mm (internal width) Livewire  wheelset.


Hotwires are protected by our 2 year warranty as well as our Crash Replacement Plan which provides $200, no-questions-asked, repair or replacement for damage not covered by our warranty.  Finally Hotwire SPM™ and SPSL™ hubs are covered by our Lifetime Guarantee.  Click the links below to learn more about each of these protections.

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! Gear of the Year

James Stout,

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
