Beating People on the commute who have a better bike

As Malaysian said "glad to have someone setting the pace" Simply using someone as a pace bod is normal. It's the person's reaction which is daft. I guess M only 'raced' as the person was making such an obvious effort to leave him behind.

I'm only bothered by this when the person sits on my wheel. Otherwise, more power to you and it makes me feel good for being considered good enough to set the pace!

But passing and then slowing down, as has been discussed here ad nauseum, is super annoying. This happened to me this morning by a dude on a mtb that was too small for him. As I passed him again I said, "Dude, if you're gonna pass someone, make sure you stay faster than they are". At least he chuckled.
