Bike ride around the Wirral

I had a day off work and had a ride around the Wirral from my home in Chester, stopping for a pint and lunch part way round. Also on Strava   / strava   The annoying clicking noise from my GoPro handlebar mount is still there. I'm sure it's caused by the foot of the quick release mount moving slightly inside the corresponding part of the handlebar mount. At the end of the ride I could see some wear on the foot where it's been rubbing. Not sure how to fix this really without getting a mount which solidly connects it to the handlbar (i.e. no quick release). I'll first try the current arrangement on another bike and with a different quick release
