I ve 2 AF road clutches, the first one I bought 2nd hand off someone on FB and is a 46 toothed and I had to convert to Li nipple operation. The feel was very light but it snatched on pull away which was very annoying but I sort of got used to it. Rode down to Adria and whilst there I checked the gearbox oil which was a little low but not by much so topped it up and the snatchiness had vanished
I just bought another one new from AF and contemplated stripping and fettling but the cassette seemed to slide in smoothly so I took a chance and it is absolutely fine, as smooth as silk. This one is a 47 tooth GP operation though so I wonder if that might have some bearing on the issue?
