LunaCycle has some gears.
Thanks LunaCycle for having all the items to repair my BBS02. A cracked reduction gear cover allowed dirt to enter the housing, which wore the teeth out on the large gear and pinion gear. I didn't need a gear puller, just a piece of wood and a hammer, to separate the large gear from the axle. The new gear went on fairly smooth and works like a charm along with the new pinion gear and a lot of Mobilgrease 28.
