Well kinda, I guess with no teeth it could be called semi synchronized. The teeth just give it the last 1/8"or so of alignment/syncronization. When flat footing and shifting hard it goes right in, and has nice street manners as long as your teeth are sharp, the ring friction surface is fresh, and the oil is not too thick.
