I'm building a Surly LHT up for commuting to work on Mondays and Fridays (hauling clothing and food...I'll ride the Madone Tuesday through Thursday).
On my road bikes, I've ridden Shimano clipless for years, but want something a bit more pedestrian-friendly on this bike.
So, I'm looking into various "clipless+platform" combinations.
Jenson USA has a pretty good deal on this shoe/pedal combo:
Only $110 for walkable shoes, and a pedal that can be used clipped in or with just the platform.
