The Renthal Fatbar is the ultimate aluminium downhill race handlebar, designed to be the ultimate combination of lightness, strength and durability. Renthal® Fatbar® handlebars are designed to ride faster, jump further and last longer. Features: High-strength 7 series Aluminium Alloy Shot peened for increased fatigue life Corrosion and abrasion-resistant hard anodised finish Laser etched positioning grid for easy set up Width marks allow personalised fit adjustment Permanent Graphics Additional Info: Race Weight - The all new Fatbar is at a much lower weight from just 315g. This has been achieved with more efficient use of material, removing any excess to reduce weight, whilst retaining the strength, durability and flex characteristics of the original Fatbar. Race Geometry - As well as reducing weight, width is also increased up to a full 800mm. The Fatbar features proven 7° back sweep / 5° up sweep combination and is available in 10, 20, 30 and 40mm rise options, to suit any bike and any rider preference. All rise options are also available in both 31.8mm and 35mm diameters. Race Winning - The Renthal Fatbar has already gained cult status, as the aluminium handlebar of choice for World Cup downhill. Eight World Championship gold medals have been won using the Fatbar, cementing it as one of the most successful race products of all time. Aluminium Tech - The Renthal Fatbar is constructed from exclusive, High-strength, 7 series aluminium. The material and specific heat treatment processes have been carefully selected to give the ultimate in strength and durability. Ultra Durable - Millions of tiny steel shot are blasted at high velocity at the Fatbar, leaving a textured surface finish. This shot peening process vastly increases the fatigue life and hence durability of the handlebar. Hard Anodised - The Fatbar features a hard anodising surface treatment. This finish is far superior in abrasion resistance to standard anodising, to keep your handlebar looking new.
