Polo Bikes

if you're using "standard" spds then you're probably using multi-release cleats. Single release cleats only unclip in one direction.

I don't think so. Multi-release are far less common, and only come with single-sided touring-style pedals. You can buy them separately, though, obviously. They're silver too. They are supposed to release in various directions (i think variations of 'sideways' up to but not including 'upwards'). I usually sell them to people who are very nervous about using SPDs. Never considered using them until now.
