Hello Brian, have been using the fabulous wheels you supplied me for a couple of months now and the results are just fantastic. I must admit I got a bit of a shock first time out on the boards as I under estimated the speed and acceleration these babies had over my previous wheels. They spin up and hold speed so well that I found myself on the pedals trying to avoid running into the guys in front of me. They look absolutely magic on the bike and perform the same on the track. Sprinting is much more controlled as the bike is far more stable under efforts and they track dead straight. My times have come down as a result of the performance of the wheels and I can’t ignore the added confidence they have given me. Getting plenty of feedback from the guys who can’t get over the quality of the finish. Great result Brian I could not be happier and thanks again for the advice through the selection and purchasing process. Overall an awesome experience. Cheers
