Gemini Wassat MTB Handlebar

The Gemini Wassat MTB Handlebar is the world’s lightest XC mountain bike handlebar. The Wassat delivers stiffness without fatigue in an incredibly lightweight form. The craftsmanship in the Gemini Barcelona workshop keeps the weight to an astonishing 102 grams. Gemini achieves this without sacrificing ride quality by using ‘GMN’ ovalized sections on either side of the bar clamp. These sections absorb vertical vibrations while maintaining precise steering reactivity. In addition, the Wassat is available in a ‘Performance Layup’ which increases the overall strength and stiffness when compared to the ‘Lightweight Layup’. This version also bumps up the weight by 28 grams.

 

Product Details

Key Features of the Gemini Wassat MTB Handlebar

  • Vibration Dampening Design: Gemini’s GMN ovalized sections keep fatigue to a minimum.
  • Reactive Riding Characteristic: The GMN ovalized sections also deliver instant steering response with zero flex.
  • Aerospace-Grade Carbon Fiber: Gemini use Mitsubishi MR70 Carbon, initially designed for aerospace.
  • Wide Compatibility: A standard 31.8mm clamp diameter means the Wassat is compatible with the majority of XC stems on the market.

Compatibility

This handlebar uses a 31.8 mm bar clamp size that will work with the majority of XC mountain bike stems. See Compatibility tab for more information.

Considerations

Gemini describes the Wassat as a ‘100% optimized piece’ which means the Lightweight Layup comes with a maximum rider weight 198lbs. If a higher weight limit is needed, that’s where the ‘Performance Layup’ comes in. Unsurprisingly, being a premium handcrafted product is also reflected in the price point.

Advice From Our Staff

This is the lightest XC MTB handlebar available. They are handmade in Spain and follow a rigid quality control standard which makes them a high-performance bar you can rely on. The Gemini Wassat comes at a premium, but it’s an outstanding choice for riders seeking an ultralight bar compatible with any 31.8 mm stem.

Compatibility 

Stem: This handlebar is widely compatible and will fit most mountain bike stems on the market as it has a clamp diameter of 31.8 mm.

Computers: One compatibility consideration is accessory mounts such as bike computers, as the ovalized section either side of the stem clamping area will make using a standard clamp-style computer mount difficult. This problem is avoided by stem computer mounts.
