From measuring seat tubes to building a bookshelf for all your training DVDs, the Pedro's 3m Tape Measure will handle all your metric-measuring needs with classic Pedro's style. A full 3 meters (nearly 10 feet to the mountain tribe) covers just about everything short of laying carpet in a room larger than 10 feet. But since you live in a bit of a cubbyhole with all your bikes, that shouldn't be a issue.
Measure all the things!
Familiarity: I've put it through the wringer
Works like it should! Shows metric and imperial measurements. Hasn't gunked up or slowed down even after many, many measures
