Topeak's Urban 8 Multi-Tool is designed for urban/one-speed bikes with wheels that are held on with axle nuts. It's made to attach to the bottle-cage mounts on the frame with the included tool-free bolts (so that it's easy to remove for use). This fine tool is constructed of high-strength stainless steel for heavy-duty use and corrosion resistance. It includes: 4/5mm Allen wrenches, a 15mm box wrench, 14/15-gauge spoke wrenches, tire levers (one metal, one plastic) and a bottle opener.
