BaGearA Posted February 20, 2017 Share Bought new wheels in the beginning of the year . Recently built up the bike Now every FUC#ING day I have to pump up the wheels because they are flat. Put on stans rim tape did not work , put on insulation tape and filament tape does not work, put on gorilla tape does not work. I've tried stans sealent , joes sealent , survival moto-x sealent still losing air. Today I tired 3 different valves does not work last one had a wide base , half the stem was also rubber , I put plumbing tape on , I put and o-ring between the rim and valve and put another one between the lock nut and rim on the outside. The lock nut is so tight I'm scared the rim wall could fail. Wheel i put the wheel under water the air is seeping out from the valve and eyelets and the rim tape is perfect i inspected under A bloody lamp with A magnifying glass ( no jokes) so it has to leak from where the valve goes into the rim then out from the valve and into the space between the walls of the rim and out the eyelets from there. Should I just say Fu*k it and buy A new rim ? I'm honestly hopeless FRom 40psi it leaks down to 5/6 psi in less than 6hours Link to comment Share on other sites More sharing options...

droo Posted February 20, 2017 Share Rant aside, there's zero useful info in this post. What rim? What tyre? Link to comment Share on other sites More sharing options...
Rock Guy Posted February 20, 2017 Share This is exactly why I just have the bike shop do it. There are just a couple jobs that I hate to do myself, rim tape being one and bleeding my brakes being the other. Link to comment Share on other sites More sharing options...
BaGearA Posted February 20, 2017 Share Rapide 30mm 650b rim Rock Razor 2.35 super gravity ( this tyre sat on a ztr wheel for a week without seleant and did not lose any pressure do I doubt its the tyre) Link to comment Share on other sites More sharing options...
V12man Posted February 20, 2017 Share Probably leaking into the rim at the valve - swap the valves out to ones with a better seal - a round seal - shaped like a cone Link to comment Share on other sites More sharing options...
droo Posted February 20, 2017 Share Does the tape cover the full width of the rim or is it the 25mm version? Link to comment Share on other sites More sharing options...

JacBrand Posted February 20, 2017 Share That is a wide ish rim. Use a wide rim tape, and make the hole for the valve small.Also like V12man said, use a valve with a cone shape seal http://www.rapide.co.za/product/rapide-tubeless-valves/ Link to comment Share on other sites More sharing options...

dev null Posted February 20, 2017 Share Odd. Never had such an issue after redoing the rim tape. Did you clean the rim with Acetone or Rubbing Alcohol before putting the new tape on? Also check the rubber seal on your valve. Clean it well. If that fails, get a new valve. Link to comment Share on other sites More sharing options...

BaGearA Posted February 20, 2017 Share AS I said the Filament tape and gorilla tape both covered the the entire rim. but now I have used all the gorilla tape. And all the bloody stores are closing now Link to comment Share on other sites More sharing options...
Odinson Posted February 20, 2017 Share Did you do the 'hippy hippy shake' with the wheel to get sealant sloshed around the area around the valve? What method are you using to install the tyre? If you're using tyre levers, be careful of damaging the rim tape. Also, don't over-tighten the lock nut of the stem, as you can actually shear/tear the rubber.
