Anyone use one on their CX bike? They’re showing as out of stock but I presume I could just put some old cassette spacers in there and I think the 12t sprocket is serrated for the lockring.

Got caught out on my lunchtime CX ride and had to limp back to the office pedaling slowly in top gear to avoid freewheeling and ripping the mech off as a bit of twig had embedded itself in the cassette/spokes.

Almost did but I have done as you say and dropped the 11t cog, fitted spacers behind the cassette and then adjusted low limit screw.

Yes, it’s brilliant. I run 10 speed 11-23 on road and 9 speed + HUUP 12-32 off road. I sometimes adjust the limit screw, but don’t sweat it if I don’t. I will for races, but not just bobbing around Swinley. They supply a larger lockring for 12T.

Mine’s red of course.

Any 10 speed spacer and a larger 12T lockring will work – but Shiny…
