Why don't after market chainrings come with ramps and pins?
There have been a raft of upgrade threads recently. I've got one of my own. Probably because we're all hunkering down in the cold weather doing our dream projects.
I've been wondering why it is that after market chainrings don't come with ramps and pins. I can buy a very nice Sugino crankset, with chainrings that have ramps and pins. But if I buy chainrings to change the gearing, I haven't found any that come with ramps and pins.
I guess that I don't know if this is true for the Shimano four arm cranksets. It does seem to be true for five arm cranksets.
Is there some source that I'm unaware of?
