Full details

Extended Product Information

FAQs

Does this wheel come with a thru-axle included?

No, this wheel is designed for 12x148mm Boost frames; you should reuse the thru-axle provided by your bike frame manufacturer.

Can I run this wheel with an 11-speed drivetrain?

No, the Micro Spline freehub is specifically engineered for Shimano 12-speed cassettes.

What is the recommended tire size for this rim?

The rim is optimized for tires ranging from 2.00 to 2.35 inches in width.

Is this wheel compatible with 6-bolt rotors?

Only if you purchase a separate Center Lock to 6-bolt adapter.

How often should I service the bearings?

Depending on riding conditions, an annual inspection and re-greasing of the angular contact bearings is recommended to maintain peak performance.

Troubleshooting

Excessive play or looseness in the wheel axle.

Adjust the cup-and-cone bearing preload using standard cone wrenches to remove play without binding.

Freehub engagement feels delayed or 'ghost shifts' occur.

Inspect the Micro Spline interface for debris and ensure the cassette lockring is torqued to manufacturer specifications.

Pros and Cons

Pros

  • Rapid engagement for immediate power transfer
  • Lightweight and durable alloy construction
  • Excellent lateral stiffness for better handling
  • Easy tubeless setup for improved traction

Cons

  • Limited to 12-speed Micro Spline cassettes
  • Not compatible with older non-boost frame standards
  • Requires center-lock specific rotors or adapters

Setup, Compatibility & Care

To ensure optimal performance, confirm your bike frame supports the 12x148mm 'Boost' standard. Installation requires a Center Lock disc rotor; if you currently use 6-bolt rotors, you must purchase a Center Lock adapter. For tubeless setups, use high-quality tubeless tape and valves to take advantage of the UST-ready rim design. When cleaning your bike, avoid high-pressure water spray directed at the hub seals to preserve the factory-packed grease inside the angular contact bearings. Periodic checks of the spoke tension are recommended after the first few rides to ensure the wheel remains true after the initial break-in period.
