On Sunday morning, the UK’s finest time trialists, took part in the Port Talbot Wheelers 25 mile race, a competition which saw 240 riders participating in three events. Starting at 1pm, the main class race was one that was attracting attention with the recently crowned 10 mile time trial champion, Matt Bottrill coming head to head again with former champion Michael Hutchinson The out and back course started in Glenyneth -South Wales. The course...
On Sunday afternoon the UK’s finest time trialists took part in the men’s National 10 mile time trial championship, 150 riders facing the time keeper on what is known as the UK’s fastest 10 mile course at South Cave, near Hull, It was going to be a highly contested race. Michael Hutchinson, 10 times a winner at this distance and the former competition record holder (being beaten earlier this year by Alex Dowsett), would be racing...
D2Z has been developing a disc wheel for the past three years. Our research and experience has shown that many disc wheels lack lateral stiffness causing problems with brake rub and poor response. The few manufacturers that have addressed the lateral stiffness problem have increased stiffness through the sidewall – this can lead to a harsh ride, poor tire compliance and fatigue during longer events. We have derived a new disc construction technique which uses internal carbon spars to improve vertical compliance whilst offering class leading lateral stiffness. This has led to a novel composite structure that has not been seen in wheel design before.
Many different laminates have been evaluated in order to obtain the best compromise between ride, stiffness and robustness. The final product weighs in at approx. 900 grams using the ultra-reliable and class leading DT Hub internals. Whilst the wheel is heavier than some of the narrower disc wheels available, tests have shown it to be 15% stiffer and with a width of 24mm the weight is very competitive with other discs in this class.
The wheel shape has been developed using CFD and extensive wind tunnel testing at the Drag2Zero wind tunnel testing facility with a rider to verify the performance. The rim width has been limited to 24mm at the braking surface in order to avoid clearance issues and to ensure it works optimally in a time trial frame. We have also developed the rim to work with the wider tires (23 to 25mm) which offer an advantage in rolling resistance.
The sidewalls of the wheel are curved to offer optimal performance between 0 and 10 degrees yaw. Benchmarking tests have shown that the wheel matches the competition above 10 degrees yaw, and surpasses the market leaders below 10 degrees of yaw. Due to the clearance of the drive train, our research has shown us that reducing the curvature on the drive side does compromise aerodynamic performance. Therefore, every effort has been made to keep as much curvature as possible, which means that rear derailleur clearance can be an issue on the lowest gear in 11 speed cassettes in some set ups. Our thinking is that a disc wheel is for riding fast and that it should not be compromised for the occasional need of the smallest cog.
