Strong, light and durable wheels with quality components hand built in Bristol. We use DT Swiss 350 hubs and strong and the 32mm deep, semi aero, DT Swiss RR 521 rim. We bring both these components together using DT Swiss Competition double butted spokes and Prolock brass nipples.

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.
