Today, the benchmark keeps rising at a striking pace: 25mm has become the mainstream baseline, 28mm is standard for performance builds, and Zipp’s 32mm 303 XPLR made industry waves upon its 2024 launch. Now ENVE pushes the boundary to 35mm with its latest G SES 6.7 Pro, cementing the trend toward ever-wider gravel rims. Every extra millimeter delivers tangible benefits: stiffer sidewall support at low pressures, reduced rolling resistance, optimized aerodynamic tire pairing, and better loose-surface traction.

Why gravel rims are getting wider

Gravel riding is no longer one single category. Some riders want fast road-to-gravel racing wheels, some want long-distance comfort, and others want bikepacking setups that can handle rough tracks, mud, rocks and loaded bags. This is why gravel wheels have moved away from narrow road-style rims and toward wider internal widths.

A wider internal rim gives a gravel tire a more stable shape. Instead of sitting tall and round like it would on a narrow road rim, the tire can sit with a more supported casing. That support matters when riders corner on loose surfaces, run lower pressure for comfort, or carry extra weight for long adventure rides.

The wider-rim trend is also connected to the tire trend. Many modern gravel bikes now use 40C, 45C and even 50C tires for mixed terrain, while adventure-focused riders may choose even larger tires if their frame allows it. A rim with 25–33mm internal width gives brands and builders more room to match those tire sizes properly.

Internal rim width does not only change the number on a specification sheet. It changes how the tire works on the ground.

• Tire support: a wider rim helps reduce sidewall squirm when cornering or riding with bags.
• Comfort: the rider can often use lower tire pressure without the tire feeling vague.
• Traction: more stable tire shape improves contact with loose and uneven surfaces.
• Rolling feel: lower pressure and better casing support can reduce vibration loss on rough gravel.
• Aero transition: when rim width and tire size are matched well, the rim-to-tire transition can be smoother.

For a wheel brand, this means rim width should be selected around the intended tire range, not only around weight or price. A race gravel wheel and a bikepacking wheel can both be carbon, tubeless ready and lightweight, but they may need different internal widths.

Which internal width fits which gravel rider?

For Ornan, the gravel range covers several useful width families. The 700C 30mm outer-width gravel series includes 24/25mm internal-width options. The ultralight ultimate gravel carbon rim series expands into 26/27mm and 32/33mm internal widths. The asymmetrical gravel carbon rim series provides 24mm, 27mm and 30mm internal-width choices for brands that want more precise wheel-system planning. 

In addition, currently ORNANBIKE has upgrade to 32inch gravel carbon rim to offer more choice, it deliveries superior traversability and long-distance riding efficiency. With the asymetrical design, make wheels balance spoke tension.

How Ornan gravel rims can support a modern gravel range

A strong gravel product range does not need only one rim. It should cover several rider types.

• A 24/25mm internal-width model for fast gravel and all-road users.
• A 26/27mm internal-width model for the widest all-round market.
• A 30/32/33mm internal-width model for adventure riders and larger tires.
• Hooked and hookless options where relevant.
• Tubeless-ready construction as a baseline expectation.

This lets a bike brand or wheel brand create a clear range instead of offering one generic gravel wheel to every rider. The result is easier selling, better fitment and fewer after-sales questions about tire choice.

FAQ

Is a wider gravel rim always better?

No. Wider is useful only when it matches the tire and frame clearance. A rider using 35–40C tires may not need a 30mm internal rim, while a bikepacking rider using large tires may benefit from it.

What internal width should a general gravel wheel brand stock first?

For many brands, 25–27mm internal width is the most versatile starting point because it covers a wide range of modern gravel tires and riding styles.

Are Ornan gravel rims tubeless ready?

Ornan gravel rim pages include tubeless-ready options across several 700C and 650B gravel models.

What's the benefit 32-inch gravel rim?

32-inch carbon gravel wheels subvert traditional design concepts and redefine the all-terrain adventure experience. 32-inch gravel rim's diameter is 64mm larger than that of conventional 700c wheels, it provide lower rolling resistance: the rolling resistance is approximately 15% lower than that of 700c wheels when ride in rough gravel roads. Combined with the aerodynamic advantage of the 45mm rim depth, it saves 10 to 15 minutes in total for rides over 100 kilometers.
