Reynolds Kitchens TR 309/289 XC Wheelset

The TR 309/289 XC wheelset is highly versatile, offering hub compatibility for Microspline, Shimano/SRAM, and XD Driver systems. You should be able to swap your existing cassette onto these wheels without needing to change your drivetrain setup.

This wheelset uses Super Boost Plus (157mm) spacing. Before purchasing, verify that your mountain bike frame is specifically designed for 157mm spacing, as it is wider than the standard 148mm Boost spacing found on many older or entry-level bikes.

The low-profile construction is specifically engineered to reduce rotational weight, which makes the bike feel snappier during climbs and more responsive when diving into tight corners. It provides a more compliant ride quality compared to deeper, stiffer aero rims.

Yes, they are designed for a tubeless setup, which helps reduce the risk of pinch flats and allows you to run lower tire pressures for better traction. You will still need to add your own tubeless tape, valves, and sealant to complete the installation.

A 10-degree engagement angle provides a quick, responsive feel when you start pedaling, which is particularly helpful on technical, rocky climbs where you need immediate power transfer to clear obstacles. It minimizes the 'dead zone' in your pedal stroke, allowing for more precise power delivery.

These wheels utilize TSS/PR3 rim construction, which is specifically tuned for high impact resistance. While they are lightweight enough for cross-country racing, the carbon layup is robust enough to handle the demands of aggressive trail riding without sacrificing structural integrity.
