CORIMA G30.5 GRAVEL - Carbon Front Wheel - Centerlock - 12x100mm - outline


The new benchmark for gravel wheel design and performance.

The G30.5 wheelset is the product of CORIMA ’ s extensive experience in carbon composite design and manufacturing, bringing new levels of performance to the gravel cyclist. G30.5 rims are compatible with tires ranging from 28mm to 60mm width.

The G30.5 wheels use a hookless, TSS (Tubeless Straight Side) rim profile with an internal width of 22mm. The TSS profile has been reinforced with additional material to resist damage from impacts. To ensure proper seating between the rim and tubeless ready tires, they have been designed to strictly adhere to the ETRTO standards. This allows for easy tire setting and inflation with no risk of the tire coming off.

The rim is produced with a patented system by CORIMA called INTERNAL FOAM CORE OVERPRESSURE PROTECTION SYSTEM. In the case that air leaks around the valve core or rim tape during initial setup, this system allows air to be released through a check valve to avoid over pressurizing the rim.

In the meantime the sealant liquid is being effective, the internal air leaks are forwarded and put out of the rim via a silicone check valve. With this system there is no over-pressure possible and mechanical over-constraints in the rim’s structure (exploding risk).

Version for folding and clincher tires, disc brakes and 12x100mm thru axle. Tubeless Ready

Made in France
CORIMA’s know-how is unique and the company is well known for its constant innovation. CORIMA have been manufacturing high performance carbon wheels since 1988. Due to their experience in working with composite materials, CORIMA controls all of the steps in the manufacturing process to make your product “unique“.

Special care is taken with every wheel build. Each of the spoked wheels are hand-built. During the wheel building process the spoke tension is constantly checked with a tension meter to ensure the highest quality build and to keep the wheel running “straight” and “true” over time.


Included in delivery: front wheel with built-in magnet, rim tape, Tubeless Ready valve, valve nut tool and wheelbag.
