HWR GXs are designed to excel as singletrack-capable, tubeless, gravel wheels.

HWR GXs are lightweight and vertically compliant, utilizing the same US-Built, lifetime guaranteed, SPDR™ hubs as our more road-oriented RLR 30s, yet by incorporating the rim from our Hotwire XC race wheelset they're also more than durable enough to tackle your most challenging gravel missions. 

Their 25mm internal width supports large volume gravel tires and delivers precise tracking in rough conditions.

Vertical ride compliance and torsional stiffness is improved by the use of SPDR™ straight-pull hubs and 24 Sapim CX Ray, semi-areo, spokes per wheel, laced two-cross (straight-pull hubs from many other hub makers count the spoke lobe as one of the crossing points and call this design "3-cross") .  

The 25mm internal width, and Str8 Wall™ sidewalls of the HWR GX are intended only for tubeless or tubeless-ready tires with widths greater than 38c.

Gravel riders who stick to gravel roads and/or pavement, or those who want the flexiblity to run smaller volume, or non-tubeless tire set ups should check out our RLR 30 wheelset.

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
