It depends on the type of Albins transaxle.
We are pretty well stocked on gears for the sequential units as of today.
If you have an H-pattern synchronized trans, Albins has cut back on the wide range of ratio's they used to offer. We now only carry the common 2 or 3 ratio sets in stock (which covers 95% of the units still running). These can be limited at times as we only stock a few sets per ratio, and we are occasionally waiting for a resupply from Albins, which can be a few weeks if they have them in stock, or a few months if they have to be manufactured.
