Pedro's 3m Tape Measure $10.95
Measure twice, cut once.
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.
