Javax ER521 Ratchet Disc IS6 carbon 29" enduro wheels

Description

Go full speed, 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 ER521 designed for enduro bikes, you get the right mix of liveliness, stiffness, and control. You can rely on them in technical terrain, they hold in fast sections, handle edges and steep impacts, and turn your power into instant acceleration.

The quick response is ensured by the precise Ratchet 36T system, so the bike reacts without delay even in technical sections. Carbon rims bring high torsional stiffness while damping vibrations, allowing you to maintain your line even in broken terrain. The Boost standard increases the lateral stiffness of the wheel build, and the IS6 (6-bolt) disc mounting ensures reliable compatibility with brake discs.

Rims made of high-quality carbon composite are designed for enduro weight, are stable at high speed, firm in banked turns, and responsive upon landing. The internal profile is optimized for modern trail and enduro tires, ensuring a secure fit and effective performance even at lower pressures. Durable industrial bearings and effective sealing keep dirt and water safely out. The spoke layout is crossed for balanced stiffness and comfort and uses robust components to maintain form and precise truing over time.

The Javax ER521 set uses the standard Boost (15×110 mm front and 12×148 mm rear). Brake discs are mounted via a 6-bolt interface. Engagement is ensured by the Ratchet 36T for a quick response. The rims are tubeless ready, ready for tubeless setup, reducing the weight of rotating mass and providing better traction and puncture protection. The rear hub is offered with a freehub 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.
