Which Clipless pedals?

They are easier to walk in, have more grip, a recessed cleat and are just generally more practical.

This.

Also they tend to be double sided, making it easier to clip in at light.

No reason why you wouldn't run them on a road bike for a long distance ride.

(Ordered the Giro Privateer as well, fit very well like a Sidis, and should preserve my rather appalling looking Spes carbon shoes).
