our hubs

Just Riding Along wheelsets are built around premium quality hubs from Bitex in Taiwan. We have used these hubs on all of our own-brand wheelsets since 2014 with proven reliability and durability.


All wheels include a 5 year warranty on hub shells, and 3 year on all other parts.

Bearing wear is not included.


6 pawls in 2 groups engage the drive ring inside the hub shell. The groups are offset slightly to double the points of engagement (POE) for a fast response to pedal input. M-type hubs have 54 POE, R-type hubs have 48 POE.

about your wheels

custom built wheels

This wheelset is built to order. We hold most parts in stock and build them after you have ordered. The build time is advertised on the front page on under the title.

what’s included

  • Wheels are set-up with the axles and freehub you have selected.
  • All wheels have tubeless tape applied.
  • There are no additional parts provided.

build quality

During the building process all components are bedded in, stretched, and tensioned repeatedly so the wheels won’t go out of true. We inspect, check and finish every wheel with equal care.

handbuilt in the UK

We built the wheels in our York, UK workshop.
