Yep. Theres a rider in Germany takes his 29 down the autoban and ive asked him to use ulysee speedo app next time as im sure a more accurate top speed would be shown. Although at legal speeds comparitvly my speedo is only 1mph out through out the range when using ulysee. Above this, at my err.. Local test range, my speedo goes wildly out and just video of the speedo would be pointless.
