The Alta 650B is designed for the wildest gravel roads and adventures. The first 650B wheelset in our range delivers all the benefits of the smaller rim size, allowing for greater tyre clearance and sharper, more responsive bike handling.
The Alta 650B is also available with a dynamo hub to power even the longest adventure. Built around the SON delux 12, the Alta 650B Dynamo will keep you charged up without holding you back.
With an internal diameter of 25mm, the hookless rim is perfectly suited for the widest gravel tyres. Enabling you to run a lower tyre pressure, giving a smoother, more comfortable ride, whilst maximising grip and traction on rougher terrain. The Alta 650B is tubeless-ready when fitted with our tubeless kit (or similar).
The Alta 650B takes our proven rim profile and applies it to the smaller 650B size. Without the requirement for a braking surface, our disc brake rim profile has been designed for the optimal rim/tyre interface. Our precision-machined alloy hubs are fitted with high-grade EZO cartridge bearings to deliver smooth running in all conditions and use a Centerlock disc fitment. The hubs are fitted for 12mm thru-axles front & rear, however adapter kits are available for other axle standards. We use a 24-spoke 2-cross pattern front & rear to ensure the Alta 650B is robust enough for whatever you throw at it.
Each wheelset will ship with:
Rim tape fitted
Freehub spacer for 8/9/10 speed cassettes
Please note: Shimano/SRAM 11-speed freehub fitted as standard. Please contact us fora SRAM 12-speed XDR or Campagnolo freehub.
Safety note: The Alta 650B uses a hookless rim, so must be fitted with a tubeless tyre. You can use an inner tube if preferred, however the bead hook tolerance on a tubeless tyre provides a secure fit with the hookless rim.
