The slam crank separator made by Ceramicspeed has a copycat product on Ali...
Ceramicspeed is 400,000 won
Ali is 50,000 won haha
Because of the slam's crank separation that fits the crank arm length
I didn't want to adjust the crank arm length, but
I guess I'll have to buy one.
*Of course, there is also a method of separating using butyl tubes uploaded by Bikeoroid. Please refer to it haha
