ORNAN 32-inch gravel carbon rim with 27mm internal width and 45mm depth

After the mountain bike world has gone through to 32-inch wheels, gravel rim is available for 32-inch size now.


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, delivering superior traversability and long-distance riding efficiency. Why Consider a 32-Inch Gravel Wheel?


-Smoother Obstacle Approach
A larger wheel diameter creates a shallower approach angle when it meets a rock, root, rut or broken surface of the same height. This may help the wheel roll through irregular terrain more progressively when the bicycle, tire and pressure are correctly matched.
-Momentum and Directional Stability
The larger format may help maintain momentum and track steadily across long gravel sectors and uneven surfaces. This can be useful for endurance-oriented riding, but acceleration and handling also depend on total wheel weight, tire mass and bicycle geometry.
-A Platform for High-Volume Tires
The 27mm internal rim width is intended for high-volume gravel tires within the published compatibility range. Final tire shape and mounted width vary by tire model, casing and pressure, so actual clearance must be measured on the complete bicycle.
-More Proportional Custom Geometry
For some tall riders, a purpose-built 32er frame can provide more proportional wheel-to-frame dimensions. 

32-Inch gravel carbon rim series is 27mm internal with and 33mm external width, the 27mm internal channel supports the intended high-volume gravel tire range, while the 33mm external width creates a controlled transition between the rim and a compatible mounted tire. The 45mm profile is designed for riders and brands seeking a deeper gravel rim shape. 2.8mm Asymmetric Offset design helps reduce the difference between left- and right-side spoke bracing angles and can support a more balanced spoke-tension distribution.
