The HR25 is built for adventure riders who refuse to follow a script—loading up for fast & light bikepacking missions one weekend and chasing friends down singletrack the next. It’s for riders who push their comfort zones and need rims that won’t hold them back.

The HR25 is the lightest and most capable gravel rim we’ve ever made. Delivering the width, stability and strength of a mountain rim with the lighter overall weight of a gravel rim. Exploring off the beaten path is its bread and butter: light on the climbs, stable on the rough stuff. 

At NOBL, our interpretation of gravel riding has never been cookie-cutter. Where we ride, “gravel” often means steep and loose service roads, chunky singletrack descents, and even a dash of hike-a-bike. A big day in the saddle can cover mixed terrain with countless curveballs, so we needed a rim to handle any surface confidently and efficiently.

With the HR25, we now have a true off-road adventure rim built for the way we actually ride. It’s versatile across the full spectrum of off-road adventure riding, light enough to make gravel laps feel effortless yet strong enough to handle spicy descents.

The HR25 slots perfectly between our gravel-focused HR35 and our XC mountain rims. Compared to the HR35, it’s shallower, wider and 80g lighter for a set, making it better suited for ultra-distances and long climbs. Compared to our XC rims, it has a slightly deeper profile that boosts stiffness, efficiency, and power transfer. Win, win!

With a refined gravel layup, the HR25s weigh just 760g per set, 360g up front and 400g in the rear, for bikepackers seeking extra stiffness and/or Boost compatibility, 28h rim options are available at 400g a piece.

The 27mm internal width is optimized for high-volume 45–60c (1.75–2.35”) tires for control, comfort, and traction on unpredictable surfaces.

Hookless rim bead ensures reliable tubeless performance and impact resistance.

RAW Finish + Coreform Technology deliver rims with a perfectly smooth interior and raw carbon exterior, both built with the highest precision.

Following our Full Custom program, you can choose a 24 or 28-hole count, pair with road or MTB hubs, and dial in your build with custom spokes, nipples, and decals.

Lifetime Warranty – Call it Adventure Insurance. Wherever you take the HR25, we’ve got your back.

The HR25 is more than a gravel rim—it’s a tool for Type 2 fun… and plenty of good, pure Type 1 fun too. If you’re the type who studies maps and thinks, “I wonder if that route goes?”, this is the rim to help you find out.
