Components

The perfect advantage

Perfect fitting

Only ones in the market offering a wrist angle regulation so you can fine-tune your position and avoid pain.

Combined with our patented K wedges to increase the angle from 10º to 15º or 20º, giving you the best position possible.

Carbon fiber body

Built using a 100% unidirectional carbon monocoque, Masamune achieves a superior strength-to-weight ratio ideal for demanding long-course athletes.

Soft, cushioned foam

Our armrest foams use a high-density lightweight compound designed to absorb micro-vibrations and prevent pressure buildup over long distances.

Interchangeable grip

Choose between the Mono or Duo grip to further customize your ride.

One Masamune carbon fiber armrest with hook and loop

- One Handgrip
- Two arai foams with hook and loop
- Four M6 Stainless steel screws with four locking washers and four flat washers

(Computer mount and bottle mount sold apart)

Carbon fibre can just be wiped with a clean cloth and water.

Try to cover the foams from the sun as EVA foam tends to expand and therefore lose its form
