blocky Posted December 4, 2007 Author Report Share Posted December 4, 2007 Cheers Marky boy... Being an ex car mechanic i've heard variations on that one once or twice The reason I asked is because I keep tearing the valve out of my tubes yet i'm doing up the clamps as tight as I dare or maybe i'm just getting too old Quote Link to comment Share on other sites More sharing options...
zippy Posted December 4, 2007 Report Share Posted December 4, 2007 This is the way I have always done the rimlocks. inflate tire to around 25psi or whenever the bolt of the rimlock stops pushing out as air goes into tire. In my mind this means it is as close to tire/rim connection as it can get and will be holding just the bead against the rim. once there tighten the hell out of it! Make it tight and then 1/2 turn more. Hope this helps or at least give Copie some fuel for comments about us rednecks. Quote Link to comment Share on other sites More sharing options...

Just a thought... are you using a jam nut on the valve stem itself? If so, leave this off as it will allow for some movement without tearing it from the tube. I have always run tube type tires this way on off road bikes as well as trials (tube type wheels). If the tire does spin (even just a bit) It will simply pull the valve stem without tearing (at least at first) Keith But as I think back, I have always been accused of having loose nuts anyway.....

alan Posted December 4, 2007 Report Share Posted December 4, 2007 i always tighten things up until the bolt breaks or the thread strips (which ever happens first) then undo it 1/2 a turn. Never fails! Quote Link to comment Share on other sites More sharing options...
feetupfun Posted December 5, 2007 Report Share Posted December 5, 2007 You may not have a tyre slip problem. The tube can get pulled around without the tyre slipping on the rim. I was obsessed with rimlocks for a while till I painted marks on the rim and tyre to prove to myself that the tyre wasn't actually moving relative to the rim. Don't ask me how to prevent the tube moving though. Powder on the tube works OK until water gets in between the tyre and tube. I've found that the tube will always move one way as far as it can in the stem hole and will then generally stop the tube moving further without getting the stem pulled out. I use Thai, Malaysian and Taiwanese tubes of a smallish tube size (3.50/4.00 x 18) in Michelin and IRC tyres. Quote Link to comment Share on other sites More sharing options...
