Defo just go for standard SPDs. Bombproof, cheap, adjustable, fit wide range of shoes, double sided pedals and recessed so you can walk about without looking like a tit!
Depending on how confident he is on is bike you can get Clickr SPDs that disengage more easily but im sure he will be fine with the standard ones.
Has he ever used clipless pedals before? If not might be worth practicing in a doorway for a while or even sticking them on his MTB for a couple of rides to protect the nice bianche from getting dropped!
