Sonder Alpha 700c Dynamo wheels for recharging your batteries by pedal power in remote areas. They're light, versatile disc brake wheels for riding in all seasons. With a dynamo you'll never run out of power when your adventure outlasts the day.

  • Disc brake specific and tubeless-ready design for 28-50mm tyres
  • Sapim double butted spokes
  • 120-point engagement for quick acceleration and pedalling efficiency
  • Built to last: fully serviceable and repairable with no specialist tools required

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 -20°C so you can rely on pedal power even in extreme conditions.

For the rear we’ve used a 6-pawl freehub for instant acceleration and maximum pedalling efficiency. This gives 120 points of contact - just 3° of rotation between each click. With faster engagement, the wheels respond the minute you put the hammer down and save wasted watts.

Made from a premium KLM41 (6061) alloy, we’ve been able to maximise rim strength and stiffness for a lower weight. They’re 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 28–50mm 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.

 60-Day Wheel Ride Guarantee - love them or we'll give you your money back

If you don’t bond with your wheels, you can send them back for a no-quibble refund within 60 days. We’ll even cover the cost of returns postage for UK orders.

Made in Britain

We lace, build and finish all our wheels in our Nottingham factory, with each one getting a full quality control inspection. We’ve 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.
