My life changed when you introduced the Counter-Force Knee Wrap. I have used one and find that it works perfectly for my condition. I will be 52 next month and stall can ride as far and as “fast” as I did 25 years or more ago – I average 120+ miles per week in summer and rode 36 miles last night in just over two hours. The knee wrap maintains my patella in the proper position so that I have no pain during or after cycling. They are great! I have also been particularly impressed that you continue to improve the product after introduction. In particular, the modification to the Velcro fastener in the Counter-Force Wrap is a huge improvement – this has extended the useful life of the wrap by a considerable margin.
