Whats the point of using a $2000 calibration tool to check the alignment of a gravel bike frame when a decent mechanic can do it just as accurately with a $20 straight edge and some basic math? Are we really to believe that the added precision of these fancy tools is going to make a tangible difference in the real world, or is this just another example of the bike industry preying on peoples irrational fear of imperfection? And dont even get me started on the so-called experts who claim that a frame thats off by 0.5mm is somehow going to cause catastrophic failure or ruin your ride quality. Can anyone provide a credible source to back up these claims, or is this just a bunch of unsubstantiated hype?
