At 45 millimeters deep our HR45 (Hookless) 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 24mm internal and 29mm external width. 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 HR45 is aimed at those running a maximum of 60psi in their tires so they’re ideal for gravel or mixed terrain riding. The hookless design is suited for today’s modern tubeless setups and the resulting wider internal width supports slightly wider gravel tires. This makes the HR45’s the rim of choice for those who prioritize traction on loose or chunky terrain. CX racers and off-road adventure riders: this rim is for you.

HR45

The wider hookless design of the HR45 makes it ideally suited for lower pressure tubeless setups. While there is overlap between the intended use of the HR and CR rims the HR is the more gravel/off-road focused rim.

Featured Upgrade: BERD

Upgrade your next set of HR45 wheels with Berd spokes. 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 ride@noblwheels.com 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.

NOBL Road and Gravel Rim 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.”

 

Michael F

NOBL Road and Gravel Rim REVIEWS

“When building my newest drop-bar bikepacking rig, I needed a wheelset that could be reliable & have a large enough inner ID for more voluminous tires. While researching which wheelset to choose, Nobl was one of the companies that was on my list. 

The process & support Nobl provided from my initial inquiry, further discussions, warehouse tour in Courtenay, BC, to picking up the finalized wheel build was unreal. 

I’ve since taken the HR35 on pavement, gravel, doubletrack, and light singletrack. This wheelset has checked all the boxes for an “all-conditions” drop bar rig.”
