• ... but do not point obstacles if you don't feel comfortable enough to do it without swerving;
  • also warn before standing up on a hill (or even on the flats), as this will slightly jerk your bike backwards;
  • same when you sit back down


Personally I disagree on the brakes thing. I'd rather have the person in the front slightly feathering the brakes (really subtly) to slow down while pedalling at a much slowlier cadence, than stopping pedalling altogether, which really makes a big, instant difference in speed and also sends my brain a confusing message, for some reason. I often ride a paceline on rolling hills so speed variation is an issue, and if people keep moving a bit to the side in the wind to slow down it is really disturbing too. Your mileage may vary I guess!
