Javax DR521 Ratchet Disc IS6 carbon 29" downhill wheels

Description

Go full throttle, confidence and speed in every descent!

Do you want to feel how the bike responds precisely the moment you pedal? With the carbon set Javax DR521 designed for downhill bikes, you get the right mix of liveliness, rigidity, and control. You can rely on them in technical terrain, they hold up in fast sections, withstand edges and steep impacts, and turn your power into instant acceleration.

Fast engagement is provided by the precise Ratchet 36T system, so the bike responds without delay even in technical sections. Carbon rims offer high torsional stiffness, yet dampen vibrations, allowing you to maintain your line even in rough terrain. The Boost standard increases the lateral stiffness of the spokes, and the IS6 (6 holes) disc mount ensures reliable compatibility with brake discs.

Rims made from high-quality carbon composite are designed for downhill stress. They are stable at high speeds, firm in berms, and responsive on impacts. The inner profile is optimized for modern enduro and downhill tires, so the tires sit securely and work efficiently even at lower pressures. Durable industrial bearings and effective seals keep dirt and water safely out. The spoke design is cross-laced for balanced stiffness and comfort and uses robust components to maintain shape and accurate centering over the long term.

The Javax DR 521 set uses the standard Boost (15×110 mm in front and 12×148 mm in the rear). Brake discs are mounted through the 6-hole interface. Engagement is ensured by Ratchet 36T, for a quick response. The rims are tubeless ready, prepared for tubeless setup to reduce rotating weight and gain better traction and flat protection. The rear hub is offered with a freehub body of choice (Shimano HG, SRAM XD, or Shimano Micro Spline) for full compatibility with modern drivetrains.
The wheels are designed for demanding riders who want strength, speed, and reliability in one.
