when you relaunch don't loose that gear cover as they are around £90-£100 to replace. I know it doesn't look pretty but double tie wrap it on just incase you ever lose the screw bolt. We thought ours were secure as Peter periodically checks them, but we still lost one on the way to Hull last year. xxx
We have heard others say that but we have never had any problems with ours. I think it depends which revision of the leg you have but our bolts never work their way loose.Thats probably famous last words now!
