I know what you mean Stu - the ride down the ridge was into the wind/rain and not pleasant but not THAT bad. I was a bit knackered after the push up and we should have dropped north off the summit ridge.... we (Matt and me and Ollie who we met in the woods on the way up) didn't want to miss the ridge despite the weather.
Tired after that and had an easier day on day 2 but a great laugh with an old climbing mate who'd not really been on a bike for a few years!
Thanks for the comments. The mount is just a normal GoPro bar mount with some cut up inner tube to pad out the bar a bit. Nipped up finger tight. Seems to not move too much but camera does pick up all the noises transmitted through the frame (Hope Pro II freehub, clipping in and out etc.). Playing around with some other MYOG mounts at present.
Day 2 that long decent wind behind round the back of Cadir down to Dolgellau has to be one of the most enjoyable 30 mins on a bike and Video2 brought it all back
