It offers a race-proven ride quality that has secured six World Championship gold medals, providing elite handling and precision on the most demanding terrain.

FAQs

Can I use this bar with a 31.8mm stem?

No, this handlebar is specifically designed for a 35mm clamp diameter and will not fit a 31.8mm stem.

Can I trim the width of the Fatbar 35?

Yes, you can trim the bars using a standard pipe cutter or a hacksaw with a guide, provided you do so carefully to maintain a clean edge.

What is the sweep of this handlebar?

The Renthal Fatbar 35 features a 7-degree backsweep and a 5-degree upsweep.

Is this bar suitable for cross-country riding?

While it can be used for any discipline, it is primarily engineered for gravity and downhill racing where extra strength is needed.

Does the 35mm version feel stiffer than the 31.8mm version?

Renthal has meticulously matched the flex characteristics of the 35mm version to the 31.8mm equivalent to ensure it maintains the same comfort and compliance.

Troubleshooting

Handlebar slipping in the stem clamp

Clean both the stem faceplate and bar surface with isopropyl alcohol to remove grease; check that all stem bolts are torqued to the correct specification.

Creaking noises while riding

Remove the stem faceplate, clean the contact surfaces, and ensure the bolts are tightened in the correct cross-pattern.

Pros and Cons

Pros

  • Proven World Cup racing performance
  • Excellent balance of stiffness and vibration-dampening flex
  • Wide 800mm platform offers superior leverage
  • High-strength aluminum construction
  • Ergonomic sweep angles for comfort

Cons

  • Requires a 35mm bore stem
  • May be too wide for riders on tight, tree-lined trails without trimming
  • Not compatible with 31.8mm stems

Setup, Compatibility & Care

To install, ensure your stem features a 35mm handlebar clamp diameter. Clean the stem faceplate and handlebar contact area thoroughly before installation to prevent slippage. When tightening the four-bolt faceplate, use a cross-pattern to ensure even clamping pressure and adhere to the manufacturer's recommended torque specifications. Regularly inspect the bar for deep gouges or structural damage, especially after significant crashes. If you choose to trim the width, use a high-quality pipe cutter or a fine-tooth hacksaw with a guide to ensure a clean, perpendicular edge.
