GRP steering wheels

GRP wheels

The JEFA GRP wheels are strong and light. A modern alternative for metal and more affordable than carbon.
Jefa GRP wheels are produced in a one piece aluminium mold with vacuum technology and a foam core resulting in a very stiff light construction. The wheel is painted with a 2 component black or white finish. The 1000 mm version is the first wheel in this range and weighs 3,1 kgs. The rim is oval shaped, 32 x 26 mm. Other wheel dimension will follow soon.

Quick release wheel nut for fast wheel removal

The quick release nut is very handy when the steering wheel obstructs the free passage in the cockpit. It replaces the standard wheel nut and can be operated with a standard winch handle. This way the steering wheel can be quickly removed when not needed.
