tbourner Posted June 7, 2005 Share Posted June 7, 2005 I've got a set of hub rings that the pack say are 73mm external and 60.06 internal, but they are actually much bigger than that inside, so they flap about on the hubs!!! They fit the wheels OK but that doesn't really help. 1. Any problems of running without them? 2. Anywhere I can get the right ones? 3. How much?

Digsy Posted June 7, 2005 Share Posted June 7, 2005 I might get shot down for this, but personaly I don't see any problem in running without them. If your wheel nuts are properly tightened (103Nm) then all they are used for is the initial alignment. The torque is transmitted through the friction between the hub face and the wheel face, NOT through the wheel studs as some people think (the same way that camshafts are driven on the friction surfaces and not on the aligning dowel or keyway.

Terminator Posted June 7, 2005 Share Posted June 7, 2005 Cant wait for Chris to see the last reply:complain: nothing personal Digsy:littled: Contact Ibra at proalloys he has a supplier for rings, or import them form the US. Ibra has got a couple sizes for me for a variety of projects@ £2-00 to £3.00 each The big problem is you can not be sure that the bolt holes will pull the wheel central. If bolts should come loose, unusual I know , but if they did yoiu are totally screwed and any other unfortunate road user who gets in your way. For what it costs I say fit them and stay safe.

tbourner Posted June 7, 2005 Author Share Posted June 7, 2005 Dusty said not to bother as well, just re-tighten the bolts after a few hundred miles. I'll email Ibrar anyway I reckon. Cheers. Link to comment Share on other sites More sharing options...
merckx Posted June 7, 2005 Share Posted June 7, 2005 The torque is transmitted through the friction between the hub face and the wheel face, NOT through the wheel studs as some people think (the same way that camshafts are driven on the friction surfaces and not on the aligning dowel or keyway. Same with the large I section beams in these sky scrapers, the bolts pull the mating surfaces together but the friction between the girders holds them in place. The bolts are subjected high tensile forces and very little shear! Best to have the rings though so the wheel nuts can be located easier which will also prevent hole elongation. Especially important when some idiot is putting your wheels on too tight with an air gun. Link to comment Share on other sites More sharing options...
SilverMachine Posted June 7, 2005 Share Posted June 7, 2005 Most wheels come with spigot rings from the supplier. I had some sent with mine along with metal valves. Contact the supplier, shouldn't cost more than a tennar for a set of four! Good luck, Gaz Link to comment Share on other sites More sharing options...
tbourner Posted June 7, 2005 Author Share Posted June 7, 2005 Yeah I got some with the wheels, but they're 65mm internal. I'll get some off Ibrar I think. Gonna put the wheels on tomorrow anyway!! Link to comment Share on other sites More sharing options...
