I was there doing the black had a wee slidey moment which resulted in an off and latterly I discovered I had bent my rear mech. It was ting tinging off my spokes when a kindly Yorkshire(?)gentleman with orange shoes insisted on fixing it for me and then promptly re indexed my gears. He worked in a bike shop he said, so knew what he was doing. Wow!!! random acts of kindness from an MTBr but imagine my horror when I looked over and saw he rode an Orange 5 😉
Anyway if it was you then thanks very much! (and we never did see your missus so I hope she made it back ok as you didn’t seem too keen on waiting for her!)
