The Renthal Fatbar was introduced after a period of testing with Dougie Lampkin, with the aim of reducing weight and improving strength and rider feel. The Fatbar concept was already being used in motocross but it required some refinement to work well in trials. With Renthal’s background and history in trials they had a good understanding of
the huge difference in application and what is required.
handlebar with a brace is strong, if a force is directed from straight above, because the brace gives it extra strength. However if the blow is directed from the front or the back of the bar then the brace has no strengthening effect. A further problem was that they found the pro riders were rolling their handlebars very far forward to get the position and ride feel they required. This meant that the handlebar brace was now not in the correct position for the job it was designed to do.
The Fatbar uses a larger centre diameter and a tapered tube, which allows you to put more material exactly where it is required — near the clamps — and less at the control ends, where it is not needed, to create a bar which is stronger and lighter. It also does not rely on a cross brace for strength so is equally strong from all directions, and is not affected by how far forward the rider rolls their handlebar. This created a product which is 15% lighter and 35%
