Stopping Brooks squeaking
I've a Brooks B17 on my MTB / commuter. I've done a couple of hundred miles on it mainly on the road and it squeaks every time I go over a bump. I've been waxing it and took it off the seatpost to check its not the bolt and it squeaked when I pressed it with the heel of my hand. Is this normal? Its driving me a bit bonkers - especially as I'm about to do the hard'n'bumpy South Downs Way this w/e. Any tips for reducing the squeak, please?
