Prime Orra 650B Carbon Gravel Wheelset

Boasting a lightweight carbon fibre rim construction with tubeless ready technology and Centre Lock disc brake compatibility, the Prime Orra 650B Carbon Gravel Wheelset is fully loaded for your next gravel bike adventure.

Developed with Team Spectra, this wheelset features a T700 unidirectional (UD) carbon fibre rim build which offers an excellent balance of stiffness, durability and low weight performance wherever your backroad adventure takes you. Designed and tested in house by Prime, this wheelset is ready for riders to enjoy a confident and secure ride that’s backed up by extensive research and development. Thanks to its high-quality carbon fibre construction, it provides greater climbing characteristics without any unnecessary weight holding you back when descending. It is also highly durable for enduring the challenges associated with day-long rides across mixed terrain conditions. 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.

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 24.5mm internal rim width and a 30mm rim depth, it is ideal for fast gravel racing and riding 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 Carbon Gravel Wheelset a perfect choice of upgrade for a wide range of gravel riders and racers.

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