Following a couple of squeeky bum incidents while braking in the recent wet weather, since about 2010 I suppose that it, I've just stuck a couple of green Swisstops on the back brake to see if they are as good as reported and can handle a decent amount of kinetic energy. I'll be looking to maintain my position as rear gunner, so if anyone becomes infirm or has a technical, and ends up behind me, just watch it when I hit the brakes!
While I was at it, and with a half turn of the 'H' screw, I also brought the smallest cog back into play. It's been out for a while to be honest, but it's seldom at the end of the cassette that I'm looking for extra gears
Looking forward to catching up with you all on Saturday
