I’ve used RaceFace and Blackspire in the past. I don’t think I’ve ever put Shimano rings back on. TA are also very very nice. Well made and gear cut but they don’t have loads of ramps and pins.
On the subject of ramps and pins, I’ve just fitted some Middleburn slickshift, Hardcoat rings and I’m not overly impressed (and that’s putting it mildly). The pins on the big ring are so prominent that when I shift from the middle to the granny, the deflection on the chain is such that rather than dropping off the bottom of the chainring, it can’t because it hooks up on the shift pins on the big ring.
Looks like I’m going back to RaceFace
