Rolf patent misleading
I saw some mention of Rolf's paired spoke patent in the archives (most
recently Jobst), but I was looking at the patent today and found that it doesn't even apply to production Rolf wheels. Previous mentions of the patent talked about how prior art trumped it (Lovelace, 1890). This isn't quite right because the Rolf patent is not for paired spoking alone, but for a strange invention where they have some spokes coming radially out of the center of the hub. So they've got the now-ubiquitous pairs evenly spaced around the hub and rim, then these centerline spokes that go out to the rim symmetrically in between two pairs. Here's an image from the patent (there are 3 pairs of spokes and 3 solo centerline spokes -- for an interesting 9-spoke wheel): http://img79.imageshack.us/img79/1944/rolfpatent9bm.jpg The patent can be reviewed he http://patft.uspto.gov/netacgi/nph-P...44&RS=05931544 If that link doesn't work, look for pat # 05931544 (obtained from the Rolf Prima site) he http://patft.uspto.gov/netahtml/PTO/srchnum.htm The purpose of the invention was to eliminate front end shimmy, which they claim it does (umm, riiiiight). Needless to say, none of the Rolf wheels being produced feature this centerline spoke set, just the conventional pairs. Rolf mentions other paired spoke patents as Prior Art, noting that they don't have the centerline spokes. So, Rolf is waving this patent around like it makes their wheels special, but they don't actually use any of their protected technology in their products. As others have said, these wheels offer nothing more than high-fashion. LAME. What's even funnier that a fellow in another forum pointed me to, is that FSA does have centerline spoked wheels, but they aren't paired. LMAO. http://www.fullspeedahead.com/fly.as...oduct&taxid=49 I've learned a lot about wheels in the last year. Here's my summary of these wheels: http://www.borked.us/attention_whore3.jpg |
