What we do at GravityWorx

For the last 5 years Gravity Worx has been manufacturing and selling high quality carbon fiber rims and wheels for a variety of uses, and in a range of sizes. We continuously drive composite technology forward in order to bring you better composite bicycle components. We have rims for bike shops, custom builders, and consumers in 27.5" and 29", in 22mm and 30mm Asymmetric, 25mm and 30mm widths in ultralight SuperComp, as well as 34mm and 44mm for plus bikes. We also make the strongest carbon fiber downhill and freeride rims you can buy. We have fatbike rims in 26", with 68mm and 80mm widths that are tubeless and double wall, and cyclocross/gravel bike rims in 700c. All of our rims have parallel bead walls for strength, beadlock technology to securely hold the tire bead, and are true tubeless rims. Our wheels have all of that technology, with the added benefit of straight pull hubs that we design and build ourselves, and spokes that we cut and thread for precise wheel construction.

Active Design

Vertically Active & Laterally Stiff - Tubeless without rim tape

Our rims are designed to be very stiff laterally, for increased cornering control, but at the same time they are vertically compliant to smooth out the ride. The secret to this ride control is a spring effect designed into the rim body that allows the bead walls to flex outward during impacts and pressure spikes, then rapidly return to their original position. This is a continuous effect much like the spring on a shock absorber. At the same time, the bead wall is reinforced to ward off impacts and reduce pinch flats, and a beadlock is built into the rim bed to securely lock the tire bead in even at low pressures. The rim bed is smooth and sealed so tubless tires mount without needing rim tape.
