    Bosch Gen4 Perf Line CX stutters in Turbo after update - why? ('21Trek Rail 7)

    Yes, but remember my bike worked fine using the Gen 3 software version. It wasn't until the LBS upgraded it to the Gen 4 software that things were changed apparently. Don't know why. In fact, I remember getting my mountain bike and seeing it had Sport mode as one of the settings. I took it...
