We carry the most complete selection of chainwheel/spider/power disc crank spindle adapter (also called "hat washers) in the world.
Please read carefully and measure your application to be sure you get the one you need. Please note that adapter "thickness" is just the portion that sit INSIDE of the chainwheel spindle hole, not the overall thickness of the adapter (we've listed that as well for chain alignment/spacing purposes).
