Jefa 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. Please click on the picture for a larger view. |
