Double, single and inner / Torx head wrench

We can finally get shot of that little Shimano chainwheel peg spanner in the tool box because M:Part has made a set of chainring bolts that you can put together using a 5mm Allen key and T25 Torx wrench (which is the same one used for disc rotor bolts). We always mislaid this tool, plus it never really worked that well; a large flat screwdriver or needle nose pliers often did the job a lot better. Depending on what crank you have these bolts might save a bit of weight, but they’ll definitely be easier to install and tighten out on the trail if they do come loose.
