At Penmachno a few weeks back we were riding up a fireroad climb and encountered two guys fettling with their bikes by the side of the trail. Strangely though, there were three bikes, but seemingly only two riders.
As we looked over and asked if everything was okay, we noticed another rider, no more than six feet away from them and right on the open edge of the treeline, braced over a fallen tree and crimping one off.
We assumed they were all part of the same group 🙂
It followed that after that, every time our group stopped to reassemble, someone would say, "'Scuse me lads..", mime dropping their kecks and squatting to lay a cable. This act continued back to the campsite and into the pub later that evening.
