Hello all,
I am building my first bike.
I bought a BB with a 110mm spindle (square taper) and a new-old-stock
Shimano FC-M510 crankset. According to the Shimano's specs, this
should give a 47.5mm chainline.
My measured chainline is, however, a few mm's shorter. If I remove the
crank bolts, I can see that the right crank almost mushrooms the
spindle (2mm left), while the left crank definitely has a few more
mm's to go.
So, the diagnosis seems to be that the right crank isn't really
perfect...
What should I do? Replace the BB with a 113mm spindle?
What if I add a tiny shim between the spindle and the crank? Will it
do the trick or just destroy the crank?
Thanks,
Federico
