williams Posted March 12, 2012 Report Share Posted March 12, 2012 (edited) Hi, hope everyone is ok Well, I have Ordered a new hub and spokes and are going to lace it up with my old onza pro rim (19"). I De-laced all the old parts (took of the old spokes and hub) so now I only have to build up the "new wheel". when the new parts arrive tomorrow. I want to remove the sprocket from my onza hub (Screw on, 12t) and use it on mý new hub. and i've seen the guide on Tartybikes, but the thing is that i only have the hub itself with the sprocket on it. So how do I get the sprocket off the hub? I'm not going to re-use my hub at all, but wan't to keep the sprocket. Thanks//William Edited March 12, 2012 by williams Quote Link to comment Share on other sites More sharing options...
Rob Leech Posted March 12, 2012 Report Share Posted March 12, 2012 Have you got a set of stilsons? - these- My link If so, do exactly the same, but use the stilsons as leverage rather than the rim. May well mark the hub, but from what you've said, dosn't sound like a problem . Cheers, Josh. Quote Link to comment Share on other sites More sharing options...

Yeah I have though the same, but if you twist a whole wheel it get alot more force than just a "Stilsons" that was what I thought were the problem. You might be able to heat it up with a heat gun and make the sprocket expand because of the heat hehe thanks//William Quote Link to comment Share on other sites More sharing options...

Also, you may have trouble getting the steel sprocket up to temperature before the hub . Josh. Edit, just thought, if it dosn't do the job, whack the whole lot in the freezer overnight, much easier to get the ally to contract than the steel to expand . Plus, with the sprocket being the part you want, the heat would mess with the heat treatment processes that it has been through and inevitable lead to it cracking Edited March 12, 2012 by Rob Leech Quote Link to comment Share on other sites More sharing options...
