I make this thread just to share my experiance making my own pulley.
I have this confusion when designing my own insert pulley. Typically when looking to buy a pulley, it will describe as abec core compatible or flywheels clone compatible. But there are several flywheels clone in the market, so you’ll need to see more details into their core, specially the thickness of their spokes.
I try to classify them into two, thin spokes and thick spokes.
After knowing the differences between the thin and the thick spokes, i need to decide which one to go. I only got the thick spokes wheels core for my reference, so i decide to go with that and with a thought in my mind that if i go with thin spokes type (wider collum insert) like abec, i can not use my pulley if i want to change my wheels to the thick spokes core (less width insert collum) like mbs. But the case are different if i go with less width of the insert collum, i still can use them in both core.
Anyone who have experience with changing pulley between thin and thick core, your input are very welcome
