Strong, light and durable wheels with quality components hand built in Bristol. We use Bitex BX106 hubs and the strong and semi-aero 32mm deep DT Swiss RR 521 rim. We bring both these components together using DT Swiss Competition double butted spokes and Prolock brass nipples. These wheels are set up tubeless ready with DT Swiss tubeless rim tape.

With all of our wheels they are hand built to a high standard within 0.2mm lateral and 0.5mm radial tolerances.

These wheels are built to order and available within 5-7 days once an order is place.

Hubs - Bitex BX106

Bitex hubs use ABEC5 TPI bearings, unless otherwise stated. They are among the best quality available. They help your hubs roll faster and for longer. The hubs are easy to take apart with basic tooling for servicing.

Bitex use their own patented 6 pawl design. There are two groups or pawls which work in teams of three simultaneously. Each pawl is held in place by a spring/clip and is also given an additional coil spring. This design is fast to engage, is quiet and is very durable. It provides either 48 or 56 point engagement, depending on the hub.

- For 12mm thru-axle 100mm front and 142mm rear spacing or quick release

- For centre-lock rotors

- Colour black (If you want coloured Bitex hubs please use the form on our custom wheel page)
