Sonder Juice 100 is a highly efficient, low drag dynamo hub with a 6V / 3W output. Suitable for road and gravel bikes, it’s tested down to -20C so you can rely on pedal power even in extreme conditions.

Our alpha hubs are built to last, a durable 4 pawl setup with a 30 tooth ratchet ring gives 12 degrees between each engagement. Weve used a 4-pawl freehub for instant acceleration and maximum pedalling efficiency. the wheels respond the minute you put the hammer down and save wasted watts.

Made from a premium KLM41 (6061) alloy, weve been able to maximise rim strength and stiffness for a lower weight. Theyre also welded and pre-taped for a tubeless-ready set up to save more weight and reduce rolling resistance.

20mm wide rims are perfectly suited for 2850mm tyres, which means more traction, a broader contact patch and lower rolling resistance. Light rims spin up quickly and sealed cartridge bearings are low maintenance and long lasting.

Made in Britain

We lace, build and finish all our wheels in our Nottingham factory, with each one getting a full quality control inspection. Weve brought the build process in house from overseas to enable us to produce something truly special. We can over see the whole construction of our wheels and keep quality consistent, production efficient and reduce the impact on the planet by not shipping boxes of wheels around the world.
