New Crank

by -

I rebuilt my Super Pioneer with a new Vintco crank and fresh bore, Vintco 40 over piston and rings and NSK bearings. Bike runs like new, quiet, strong pull, no "bucket of bolts" rattle. Nice!

Don't get cheap on that rebuild.

Never rebuild an OSSA without a new crank assy. These work just like the original.
