That should work. My question is, is it that important to have your rear axle precisely torqued in the unfortunate situation of replacing a flat? You're already running compromised with a tube. At home, you're going to remove the wheel to replace the tire and can reset the torque there. So, you're going to carry an single purpose tool for every mile of every trail ride just to have the exact torque for one bolt for a handful of miles after a flat?
