Whilst the road bike is fun, I do love taking the 'slow' hybrid on the commute. Has a flat bar, toe straps, fatter-than-road-bike tyres and due to my exercise class that morning/later in the evening, I'm often in running shoes and normal shorts. When I pass a kitted-out roadie I know they're going to be rather vexed... as I'd be in a similar scenario. Can't help grinning.
If people get annoyed when someone passes, they should learn to cycle faster

I can take a good scalp, in fact I metaphorically dip my hat if dropped impressively.
