The Renthal FatBar V3 31.8 in Gold is a premium downhill race handlebar engineered to deliver an optimal balance of lightness, strength, and durability. Constructed from high-strength 7 series aluminium alloy, this handlebar is designed to withstand the rigours of demanding mountain biking terrains while providing riders with precise control and confidence. Its race-proven geometry, featuring a wide 800mm width combined with 7° backsweep and 5° upsweep, ensures an ergonomic fit that enhances handling and comfort across diverse trail conditions.
Incorporating advanced manufacturing techniques such as shot peening, the FatBar V3 significantly improves fatigue resistance, extending the lifespan of the handlebar under intense riding stresses. The corrosion-resistant hard anodised finish not only protects against abrasion but also preserves the vibrant gold colour, maintaining both functionality and aesthetic appeal. Precise customization is facilitated by the laser-etched positioning grid and width marks, allowing riders to tailor the setup to their individual preferences. This handlebar is an excellent upgrade or component for building a high-performance mountain bike, complementing the broader Bikes category with its robust and reliable design.
Is the Renthal FatBar V3 compatible with different mountain bike models?
The FatBar V3 is designed to fit mountain bikes equipped with a 31.8mm clamp diameter, making it compatible with a wide range of MTB setups, particularly those focused on downhill and aggressive trail riding.
Can the handlebar’s width or diameter be customised?
This specific model offers an 800mm width and 31.8mm diameter; however, the Renthal FatBar range includes various rise options and diameters, including 35mm variants, to accommodate different rider preferences and bike configurations.
How does the shot peening process improve handlebar performance?
Shot peening creates a textured surface that enhances fatigue resistance by preventing crack initiation and propagation, thereby extending the handlebar’s durability under intense riding conditions.
