Prime Orra 650B Alloy Gravel Wheelset

Whether you’re spending the weekend exploring the countryside or planning your next epic gravel adventure, this wheelset is developed for smooth and dependable rolling performance. Benefitting from a high-quality 6066 aluminium rim construction, this model offers a fantastic balance of strength and durability for handling the demands associated with travelling across mixed terrain conditions on your gravel bike. Developed with Team Spectra, this wheelset uses a rim that’s designed and tested in house, so that riders can enjoy a confident and secure ride that’s backed up by extensive research and development.

Tubeless Ready Gravel Wheelset

Built for the challenges of modern gravel adventure riding, this wheelset is kitted out with tubeless ready rim technology. This means that you can enjoy tubeless advantages such as the ability to run lower tyre pressures for increased stability on rough terrain conditions, lower rolling resistance and fewer chances of flats or punctures. With a 26mm internal rim width and a 28mm rim depth, it is ideal for gravel riding and training as well as for riders who want to use wider tyres.

Star Ratchet Hubs

Providing gravel riders with superior reliability, this wheelset is equipped with Star Ratchet Hubs that offer greater dependability due to each of the ratchets engaging simultaneously every time. Another highlight is this model’s incorporated notch, where the newly developed shape of the end caps simplifies disassembly significantly and therefore makes maintenance even easier. It also offers tool-free freehub conversion. This makes the Prime Orra 650B Alloy Gravel Wheelset a perfect choice of upgrade for a wide range of gravel riding disciplines.

Please note: This wheelset is only compatible with tubeless tyres.
