road magnets do IIRC, but there were ride complaints and I think Ken at PG dropped them because they weren't very good with communication or support.
Don't quote me on that thoughhhh
I have the Roadmagnets and love them. The ride is a little bumpier but not much. You can see my drop on the "Tenzos installed" forum. Hope this helps.
I'm getting my H&R's installed tomorrowI can't wait.
