Walker Brothers join record breaking attempts

Walker brothers are now proud to be part of "Team Excalibur".  We intend to set and break multiple National and World roller and vehicle paced speed records, including the world land vehicle assisted speed record.

 

Brian Walker is to design and build one a off wheel for the attempts next year. All will be revealed by the main man himself in the new year.

 

Updates will be posted here.

 

 

Again, Matt Rotherham goes from strength to stregnth riding our Revo 1 disc and HI5 wheels to Silver medal place in the Keirin.

 

Well Done Matt

Walker Brothers wheels made a great impact in the 2017 National Track Championships in Manchester.

Intended to be used by triple gold medalist Dan Bigham, there was a compatibility issue with his frame so the wheels were handed to his Brother NRG DriverPlan team mates who used it to outstanding effect, taking the Team Pursuit Gold Medal.

A fantastic first outing for the  Ethereal prototype disc wheels

Charlie Tanfield took Silver to Dan in the individual pursuit and Jacob Tipper took ninth in the individual pursuit smashing an unbelievable 17 seconds off his personal best.

The new Walker Brothers Ethereal Disc wheels out perform Mavic Comete wheels significantly in aeroynamic and performance tests

In a series of independent aerodynamic and performance tests over the past 3 weeks, the new prototype Ethereal track disc wheels have come out consistently faster than Mavic Comete wheels.

Meticulously tested by Watt Shop at Derby Veledrome against the Mavic comete and Corima wheels, the Ethereal proved significantly faster in all tests.

 

TEST 

The data was collected with a Quarq Dzero, test runs were 4 minutes at 56kph. Air density was calculated from ambient air temperature, air pressure and humidity.Tyre pressure were all set at 220psi. Crr for each wheel was calculated using the Tom Anhalt roller method. Chain tension was always set the same, (very loose). The data was processed in MatLab on a second by second basis and then averaged over the complete test run.
