Javax RX521 Ratchet Disc centerlock carbon gravel wheels 24/28 holes

Description

Hit the ground running, stability and speed both off-road and on the road!

Do you want to feel how the bike responds precisely the moment you pedal? With the carbon set Javax RX521 designed for gravel bikes, you get the right mix of liveliness, stiffness, aerodynamics, and control. You can rely on them in off-road conditions, they hold up in fast sections, and on the road, they transform your power into instant acceleration.

The rapid response is thanks to the precise Ratchet 36T system, so the bike reacts without delay both in technical sections and during dynamic changes on the road. Carbon rims offer high torsional rigidity while dampening vibrations. The 40 mm height also ensures perfect aerodynamics. The centerlock disc attachment guarantees reliable compatibility with brake discs.

Rims made from quality carbon composite are designed for gravel discipline. They are stable at high speeds, solid on gravel, and responsive to changes in speed. Durable industrial bearings and effective sealing keep dirt and water safely out. The spoke pattern is designed for balanced stiffness with 2x crossing (front wheel) and 3x crossing (rear wheel).

Javax RX521 wheels use standard axles (12x100 mm front and 12×142 mm rear). Brake discs are mounted via centerlock nut. Engagement is ensured by Ratchet 36T, for quick response. The rims are tubeless ready, prepared for tubeless setup to reduce rotating mass and improve traction and protection against punctures. The rear hub is offered with a freehub according to choice (Shimano HG, SRAM XDR, or Shimano Micro Spline) for full compatibility with modern drivetrains.
The wheels are designed for demanding riders who want strength, speed, and reliability all in one.
