I have one. Worked just fine although the cage doesn't feel anywhere near as stiff as the one it replaced.
Cheers I thought these might twist a bit as the cage body is slimmer than some of the others I've seen. Does it feel any smoother/ faster to you? mine is for my TT bike
Bearings spin a lot faster, but under load I can't tell any difference.
