Default Re: Bottom bracket advice

That's the kit crank that is included with the huasheng 4 stroke kits, I have it on my bike and hate it. The ring is just swaged onto the cotter fitting and the ring itself is out of round. The flat on the spindle is too far outboard and required filing down additional flat section to slide it over for proper chainline. I have never seen anyone selling smaller rings for that set up. I'm actually going to be switching out mine for the SBP cartridge bottom bracket once they have them back in stock. They have a keyed spindle that you can put any ring down to like 28t on via a carrier. It will cost a little more, but it looks to be a better quality part.
