25mm inner width 36mm external width gravel rim with reinforced wide bead design

Decription:

Developed around a 25 mm internal width, 36 mm external profile and reinforced wide bead structure, this carbon rim series is designed for modern gravel and all-road applications where wider tires, lower pressures and increased impact loads place greater demands on the rim.The reinforced wide bead profile increases material and contact area at one of the most impact-sensitive parts of the rim, helping distribute impact loads across a wider surface rather than concentrating force at a narrow edge. The result is a rim designed to provide better tire support, greater resistance to localized impact and reduced risk of tire pinching during hard rim strikes.

Combined with a 36 mm external width and a refined aerodynamic profile, the rim transitions more naturally into wider tires, creating a more integrated tire-rim shape for modern gravel and all-road applications.

An asymmetric rim architecture further helps optimize spoke geometry and spoke-tension balance, providing a more practical foundation for reliable wheel building.
