The Renthal FatBar V3 31.8 Handlebar is a high-performance mountain bike handlebar designed for riders who demand precise handling, durability, and confidence when riding aggressively. Developed from Renthal’s extensive experience in motocross and mountain bike racing, the FatBar V3 delivers a refined balance of stiffness, comfort, and control.
Built from 7-series aluminium, the FatBar V3 uses Renthal’s advanced manufacturing process to create a handlebar that is incredibly strong while maintaining tuned flex characteristics. The updated design improves impact absorption and reduces rider fatigue without compromising steering precision.
With multiple rise options and a comfortable 7° backsweep / 5° upsweep geometry, the FatBar V3 provides a natural hand position for modern trail, enduro, and downhill bikes. The 31.8mm clamp diameter offers excellent compatibility with a wide range of stems while maintaining proven reliability.
At Fanatyk Co, we like the Renthal FatBar V3 because it is one of the most trusted handlebars in gravity mountain biking.
A handlebar is one of the most important contact points on your bike, and the FatBar V3 delivers confidence when things get rough. The tuned flex helps reduce vibration and arm fatigue, while the strong aluminium construction stands up to the abuse of Whistler’s technical trails and bike park terrain.
Renthal has decades of experience building components for racing, and that knowledge shows in the FatBar V3. It provides a precise, predictable feel that aggressive riders appreciate — whether you are racing enduro, riding steep technical trails, or spending full days in the bike park.
For riders upgrading their cockpit, the FatBar V3 is a simple change that can make your bike feel more comfortable and controlled.
