Don’t understand any mechanic who doesn’t use one, especially those who avoid using them with platitudes like ‘ if you can’t judge blah blah blah’. I wager, without torque wrenches, most home mechanics under tighten BB’s, and overtighten brake hardware and handlebar stem bolts.
I use a Park cantilver I have had for years for the big jobs, which a child cam re-calibrate (should it need it), and a small ratchet one that does the small jobs that I got from CRC.
Some mono thought cycle mechanics seem proud to boast that they don’t need one. These individuals have magic hands and can tighten any bolt to the right torque. Well apart from their barely tightened BB’s, and over tightened stems and rotor bolts….
Very strange.
