For cycling repairs you canb either torque things or go with your gut - the problem is that going with your gut can end with cracked carbon or something that is too loose. The kit includes a bunch of bits, and a T handle ratchet that can be assembled in many ways. The torque tube is used to tighten things to a specific torque, and there is an alternate tube that is used for loosening. When you loosen you do not want to use the torque tube - if you go past its limits, you will ruin the torque tube. The package is compact so you can carry it, and there are plenty of bits to get the job done
If you need some extra leverage this is the product for you. I would think these levers are nearly impossible to snap. Nice handle area, nice build quality, and have a great tip on the end to get under the tire without damaging the tube.
