On the last big ride i was on, since we are a tandem, lots of people asked if they could draft off us. (We always let them) one gal, probably 110 lbs
tried to insist she take a turn pulling... We just told her; what's the point?
If we're going fast enough for you to draft off; draft off us; but you'll pass us
in the climbs and we'll pass you going downhill. And company is always welcome.
