Tools are security, and everybody I know and like is drawn to well-made tools that are compact enough to fit anywhere, and could possibly save the day. This isn't your average Crescent wrench. On those, you generally have to go to 16-inches to get one that opens 32mm—enough for the upper bearing cup and locknut on a 1-inch threaded headset. This one does that in 5 1/2 inches, and reduces small enough to squish a mosquito's leg. In-between, it's a 15mm wrench for pedals or track bike wheels, an inconvenient but effective 2mm spoke nipple wrench, and it can stabilize (keep from twisting) a handlebar-end pod while you tighten it in the bar. Fender nuts, rack nuts. You can clamp onto something and bend it. You can use the hole in the end as a cheater bar for a small hex wrench. Made in Taiwan to the Japan's JIS standards—the highest in the bicycle industry. If it were made in Japan, it would cost $78, and at that point we wouldn't offer it. At $40, it's not an impulse buy, but is still a decent deal, and you may never need to use a two-pound, 16-inch adjustable wrench again.
