methods of unbending chain rings? the SR CR was bent 3 mm on a chord of 20 mm from running the chain
between the chainstay and small CR while running the yellow light with the worn power link skipping
as I pressed forward.
1)A usual recommended method is grabbing one point with a visegrip and bending. experience indicates
the method usually produces one more bend rather than a straight piece,2)Or will the entire chord
section bend at once using hardwood or ply spanners from chord start to chord end, held between
vicegrips?,3) will the bend pressout? or does the pressout pressure need to approach the
material's malleable strength pointand, 4) ultimately? does the CR go to a machine shop for a
straight piece of work?
