cup and cone bb adjustment without taking the crank off

quick way to tighten most fixed bb cups without taking off the crank is to use a 36mm headset wrench. it fits most of the time to check the tightness of the fixed cup. i also grind down my pin spanners to sneak it past the left arm. new style ones that use a 20 tooth spline are a bit harder to do without taking the arms off. drive arm must come off but the non drive side i can usually wedge a screwdriver to turn the cup
