It was really loud! I've had no success isolating the sensor with cut-up inner tubes in between sensor and fork.

This wasn't a problem with my last bike's steel fork. Obviously, the carbon fiber makes a nice resonating chamber, where the steel did not--I never noticed the almost-inaudible sound before.

Has anyone else experienced this problem? And do you have solutions? I don't have another non-SigmaSport computer to try out, so I wonder if other brands don't have the noticeable click.

Thanks for your help.
