On One Pompino owners...

Thanks, yeah they are, and I will let you know once I've ridden it. They seem fairly sturdy at the moment, and I previously had them on another bike sans rattleage.

Omnomnoms were too expensive for me. I wonder if the On-One chainset that looks similar would be similarly stiff...

I've got some of the on-one omnium knockoffs, which I'm planning to fit to my pomp. I'll let you know if it works out, but I'm confident (I seem to remember someone else in this thread has fitted them with no issues).
