At 45 millimeters deep our CR45 (Clincher) rims offer an aerodynamic advantage and a dampened ride-feel while remaining light and responsive. They feature front and rear specific layups with a new 24h rear hole count. These rims have a 22mm internal and 29mm external width and can be paired with the CR35 if you’re looking for a shallower, more comfortable ride up front. Find our tire and pressure recommendation chart below for guidelines to help you determine which model is best for you.

We worked with a number of manufacturers to collectively produce S136 and P20 steel molds. These long lasting molds allow for the highest tolerances with the smallest possible parting lines. The result is a rim that comes out of the mold nearly blemish free. The mold release used flashes off and you’re left with a scratch resistant surface with the outer layer of resin preserved and the carbon fibers remain undisturbed. Our new layup uses several different types and thicknesses of prepreg which has allowed us to shave weight in low stress areas, while reinforcing the high stress areas.

Symmetric – 0mm Offset

The CR45 adds a bead hook to its design. The bead hook is essential for higher pressure applications as it prevents blowouts and securely seats the tire. Riders who want to run up to 80psi for pavement or hard-packed dirt should choose the CR45 over the HR45. The CR45 can still be used in lower pressure applications but their internal width is better suited for more narrow tires.


The narrower profile and added bead hook of the CR45 is ideal for use in higher pressure applications so while the CR45 is gravel ready, road riders will likely choose this option vs the HR45. With an added 10mm of depth, this rim will feel stiffer and more responsive than the CR35 and offer aerodynamic benefits as well.

Featured Upgrade: BERD

Upgrade your next set of CR45 wheels with Berd spokes for extra comfort and weight savings. Berd spokes are made from an advanced polymer called Ultra High Molecular Weight Polyethylene (UHMWPE). UHMWPE has 12 times the strength-to-weight ratio of steel and floats on water. This means that you can enjoy substantial weight savings, when your wheelset is laced using these spokes. We find the ride quality is slightly less stiff than some conventional spokes, so road riders desiring a high amount of wheel stiffness may prefer steel spokes. Order custom colored Berd spokes by downloading our custom Berd form and emailing it to the form is available in 24h, 28h.

*We modify all J-bend hub shells for Berd, however we do not modify straight pull. For modified hub shells, the hub shell warranty is void

Lifetime Warranty

If you manage to break your rims while riding your bike, we will send you a replacement rim at no charge and you will just have to pay the shipping cost. If you damage your rims because of non-riding circumstances like melting your rims because it was sitting too close to your vehicle’s exhaust on a road trip, we’ll give you 50% off a replacement. This coverage lasts indefinitely to the original purchaser.

Road and Gravel REVIEWS

My trip was amazing to start and was made incredible with the addition of my NOBL wheels. Light, responsive and most noticeably laterally stiff and precise on the descents-I couldn’t be more happy about how they performed over 350 miles and 33k of climbing through Umbrian and Tuscan farm roads and Strada Bianche.”
