25 Series Symmetrical Hub Sprockets

I'm building a large scale rock tumbler and these gears came in fast and were exactly what I was expecting. Good quality, no inclusions or rough spots and the balance seems to be very well too.

These work great in all sort of applications. Having everything the same style makes it easy to keep the chain aligned. Ijust wish the tooth counts came in divisible by each other increments to make speed ratios easier.

These sprockets are great. I used to get the older ones that only had a boss on one side. Those made it difficult as the flat side would need a spacer to prevent rubbing. These, with the double boss, make it easy to keep everything in place. Just wish the tooth counts were more round numbers (increments of 5 or made whole number ratios).
