Perhaps someone can save my sanity. I recently bought a Specialized turbo creo sl comp carbon evo and have this reoccuring issue every time I take it out. Whenever I am in turbo riding anywhere from 18 to 24 mph on a basically level road, the bike will periodically grab. It feels like the bike is braking for a split second and then I hear a click in the motor. Sometimes the grabbing is very noticeable. I am usually spinning between 80-90 rpm's. When I compare this to coasting without pedaling, it is a completely different feeling. It is hard for me to believe that I am the only experiencing this issue. As a cyclist for the past 50 years, I do know the difference between when a bike coasts freely and when it feels like it is braking.
