Cant believe I have to ask this, but apparently some of you need to be told: whats the most basic, mind-numbingly obvious mistake to avoid when using bike tools that you guys are still managing to screw up? Is it really that hard to figure out that you need to tighten the quick release in a star pattern? Or that using a torque wrench is not just a suggestion, its a requirement? Or maybe its just a lack of common sense thats leading to all these stripped bolts and mangled derailleur hangers? Seriously, whats the most elementary error that youre still making thats causing you to ruin your own bikes? Inquiring minds want to know...
