They are fucking fantastic.
Got home from work, got changed, filled the camelbak, popped the mini-disc on, and headed out. I did a different route from the last two rides, there is less offroad, but it’s a nice little ride with a couple of fast descents on narrow tracks. It made a change riding while listening to music, I don’t normally bother. The ride took about 79 minutes in the end, had 285m of climbing, mostly in the first few miles, and was a shade under 12 miles in total. I’m knackered now, but loved every minute of it.
