Shouldn't it do that constantly? It doesn't- only starts after about 15 minutes and only if I'm in a higher gear, riding fairly hard. I'm not standing up because I'm still rehabbing my knee, so I'm not really going all out. It always stops if I slow or stop pedaling.
Once I finish clean/lube and setup for my road bike, I'll try it with that one to see if it still happens.
