Carbon parts carry a torque figure, and guessing it is the expensive way · review
A 19-function multi-tool with hex keys, open wrenches, spoke wrenches, Torx bits and a chain tool for 8 to 12 speed, at 175 g.
Our conclusion The multi-tool to carry when one tool has to do everything.
The M19 is one of the most common multi-tools on Amazon.com, with more than 17,000 ratings. It lives up to that because it covers almost any repair on the road.
Hex wrenches from 2 to 8 mm, 8 and 10 mm open wrenches, spoke wrenches #0 to #3, Phillips #1 and #2, a flat #2, Torx T-10 and T-26 as listed, a chain tool for 8 to 12 speed, side grips, a length of 89 mm, a weight of 175 g, and a lifetime warranty.
A broken chain ends a ride unless you carry a chain tool, and many small multi-tools leave it out. Modern 11 and 12 speed chains are narrow, and a tool has to be designed for them. This one states it.
Note that the listing says T-26, a size we would double-check, because T-25 is the common bike size. At 175 g, it is a heavy pocket item, and on a short commute the ROCKBROS or a simple hex set would be plenty.
