It could be that I took too shallow an angle going back onto the path but I don't think I did.

Often when I've been stopping, even on a flat bit of road I feel the bike is leaning over to the right. The brakes are not pulling so it's not that. I took the bike back to the LBS a couple of weeks ago and they said (rightly or wrongly) that it's because the tyres have no tread in the middle but tread on the sides. I admit I was neither impressed or convinced by that statement but could see how it could have an effect.

I don't have this problem with my Raleigh (also a Racer), just with the Dolce.

Ah well. They say everything runs in 3s so that is the third time (in my life) I've fallen off a bike.
