Sette 21 Function Multi Tool
Sette 21 Function Multi Tool features 21 tools that allow the everyday rider to carry their toolbox with them on the trail. The ST-03 includes: 1.5, 2, 2.5, 3, 4, 5, 6, and 8mm hex wrenches, Phillips head screwdriver, Flat head screwdriver, T25 wrench, 8, 9, 10, 13, and 15mm box end wrenches, bottle opener, 3 spoke wrenches, tire lever, and a universal chain tool. The ST-03 breaks away into two pieces by quick release push buttons for easy use and has the ability to lock out the tools for maximum performance and safety.
I bought this to keep on my bike since it has all the useful stuff for emergencies. Though I think the for a mountain bike some tools are not so useful like the closed box wrenches. The way the two sides attaches is clever. You press the two sette logos to detach - took a few seconds for me to realize this. Pack this tool + an SRAM chain link and you'll save yourself a bad ride should your chain break off.
