I'm converting my 21 speed 1997 GT Backwoods to a single speed
I've completely stripped the bike down, minus the cranks.
These are Shimano Alivio cranks.
I removed the allen head screws from the cranks and it appears the
ends of the spindle are square. However, there appears to be a square
drive washer threaded down into the crank arm. Am I correct in assuming
I need a 1/2" drive ratchet to back this washer out?
I though the crank arms would just pop off like an old school BMX crank, but
obviously not after a couple whacks with a mallet.
Thanks for reading
