Hi, I have just fitted a replacement inner chainring to my FSA chainset, using a SRAM 34t item purchased from Tredz. It fitted easily enough, and seems to work fine in use, shifting ok between chainrings. However, I subesquently came across a video which seemed to suggest that the little tab (between bottom 2 attachment points on image below) should line up with the crank.
I can't see any shifting ramps that would be affected so, before I start mucking around with something that seems to be working well - do any of you folk know what is the significance of lining this tab up with the crank?
Thanks, John
