mudman Posted January 15, 2005 Report Share Posted January 15, 2005 Hi, Air has been leaking through where the spokes go into rim, have checked spoke tension and used silicon over topof spokes inside rim, but air is still leaking. Has anyone had this problem and is there a better cure than the silicon trick has this has not worked. thanks in advance Quote Link to comment Share on other sites More sharing options...
nigel dabster Posted January 15, 2005 Report Share Posted January 15, 2005 Look at it this way the rim is leaking not the spokes. Need to make sure that the tape is exactly where it should be and then it will seal. Thats how they come from the factory. It can be a pain and I have spent many hours avoiding silicone, but not sure its worth it. Best help is to go to rypusa and look at waynes tips explains it very well.

alan bechard Posted January 15, 2005 Report Share Posted January 15, 2005 I use "slime" tire sealant as a lubricant to install the rim strip. Doug came up with this and it seems to work very well for several of us. And as HondaRS suggested, spotlessly clean is also important.

marky g Posted January 15, 2005 Report Share Posted January 15, 2005 Binned the tape on my SY250 and used 'sikaflex', we use it at work, goes off like rubber, no leaks any more . I thing worth checking is the valve, replace it with a new one for the sake of a few quid Quote Link to comment Share on other sites More sharing options...
nigel dabster Posted January 15, 2005 Report Share Posted January 15, 2005 The only real argument against silicone is that if you adjust or tension the spokes it can upset the seal and if you ever go for a true up its a mess. For a one off or if you are going to sell its fine. Quote Link to comment Share on other sites More sharing options...
physco Posted January 15, 2005 Report Share Posted January 15, 2005 remove the rubber sealing ring.give every thing a good clean.then clean with contact cleaner.use plenty of the white rock oil water proof grease and replace the rubber ring.blow up the tyre and the grease is forced into the spoke nipples and is made air tight.this is what the top trials teams do and it works a treat.silicone is a waste of time.

nigel dabster Posted January 15, 2005 Report Share Posted January 15, 2005 Sorry rs you are a bit off on this one, for most servicable rims silicone is best avoided, physcos spot on, works teams or not the sealing bands are not expensive.

nigel dabster Posted January 16, 2005 Report Share Posted January 16, 2005 Its more of a longer term thing if I get my wheels trued I know the wheel buider uses wd 40 to ease the nipples so think the silicone would never seal anyway and thats not the way it was designed. Sort of bodge that works thing. Quote Link to comment Share on other sites More sharing options...
mudman Posted January 16, 2005 Author Report Share Posted January 16, 2005 Thanks for the ideas, I might give the waterproof grease a try or what does anyone think about using slime instead of the grease? Quote Link to comment Share on other sites More sharing options...

kinell Posted January 16, 2005 Report Share Posted January 16, 2005 Binned the tape on my SY250 and used 'sikaflex', we use it at work, goes off like rubber, no leaks any more Last year, I had a slow puncture because of air leaking out of the spokes. I had tried siliconing the spokes twice without any success. I got a new rear wheel from JLI's and mentioned it to Gary who gave me the following advice: - Fit the rim band and use 'sikaflex' to seal both sides of it to the wheel. It's main use is fitting windscreens in cars as it doesn't set really hard, it sets like a soft flexible rubber beading. I did both wheels in 10 minutes and left them overnight to go 'off' before fitting the tyres. Neither wheel has leaked since Quote Link to comment Share on other sites More sharing options...
kevin j Posted January 16, 2005 Report Share Posted January 16, 2005 can you give more onfo on this 'sikaflex'? The name may not be available here, but apparetnly its a windshield sealant for autos that might be similar product here. I have used the green Slime product with good success. Works pretty well with tube type tires also. The down side on tubeless tires is that repairs are a terrible mess inside when the time comes. also, be cautious about the stuff getting out of the valve stem. The tiny fibers in the slime product seem to make the valve stem leak later on, when you are letting out a bit of air the stuff blows back out into the stem seat. kcj Quote Link to comment Share on other sites More sharing options...
timp Posted January 16, 2005 Report Share Posted January 16, 2005 Grease works for us and helps stop corrosion setting in on spokes Mark T Quote Link to comment Share on other sites More sharing options...
marky g Posted January 16, 2005 Report Share Posted January 16, 2005 (edited) Here it is, great stuff.......bit messy if you get it on your hands though it says it will adhere to: GLASS, STEEL, PVC, ZINC, FIBER CEMENT, ALUMINIUM,MARBLE, WOOD......the list goes on. Mail me, I'll see what I can do Edited January 16, 2005 by Marky G Quote Link to comment Share on other sites More sharing options...
