NotSoBigBen Posted August 4, 2008 Share So what ghetto tjoopless have you tried? If other please specify. Multiple votes allowed for you 'scientists' amongst us! Most know that I have done the BMX tjoop conversion but have yet to find removable core ones. If you use the 'cut out of a tjoop valve' then how do you seal the rim? I'm scheming how about a BMX tjoop with the valve cut out and 'replaced' with a removable core valve from some other tjoop! 1) How do you get the cut out valve to seal nicely with the valveless BMX tjoop? 2) In fact do you even need to or do you just tighten the valve retaining nut snug against the rim will it work? Your thoughts oh knowledgable dirty ones? Link to comment Share on other sites More sharing options...

dirtrider Posted August 4, 2008 Share Insulation tape to seal rim cut out valve to seal the big hole in the rim never had to specially seal the valve , just tighten the screw . Link to comment Share on other sites More sharing options...
NotSoBigBen Posted August 4, 2008 Share Thanks DR, that insulation tape option just seems a bit 'Heath Robinson' to me but if it works with insulation tape then my idea with valveless BMX tjoop will work as well and will be a lot more 'professional'!

AndreZA Posted August 4, 2008 Share I guess if you go with DR method and you do have a problem with the piece of tube not sealing then you could always just glue it down with either a bit of wood glue or spray on glue. Link to comment Share on other sites More sharing options...

He would probably try weld it and on failing, staple gun it. Link to comment Share on other sites More sharing options...

IanJ Posted August 4, 2008 Share What's the thoughts on drilling the hole in the rim to take a schrader valve bmx tjoop? Is there any inherent problem with schrader valves? Link to comment Share on other sites More sharing options...
dirtrider Posted August 4, 2008 Share OK I will not recommend doing what I did , the only reason I tried is was because I wanted to see if it will work . When it eventually fails and I have to remove the tyres then I will most probable do the BMX things , unless somebody got another bright idea of doing it !

I don't see any problem with that but ....................................... no self respecting mountain biker would ever ride a bike with Schraeder valves, nearly as bad as bar ends on riser bars man Link to comment Share on other sites More sharing options...
IanJ Posted August 4, 2008 Share How did I know that was coming BB . My wheels had Schrader when I got it and the bmx tubes are easy to get hold of. Converted to tubeless some time ago and it has been working like a charm. Link to comment Share on other sites More sharing options...

Converted to tubeless some time ago and it has been working like a charm. The only issue I have with the BMX is when top up time comes it isn't that easy but is do-able though ............ What sealant did you use BTW? I have done my last one with OKO and so far so good! Link to comment Share on other sites More sharing options...
IanJ Posted August 4, 2008 Share Used some of Sonic's Stan's. Have probably had about 5 punctures since then and all have sealed within a few seconds. Had one big one at Groenkloof when I landed on a rock and I had to stop and bounce the wheel a few times to get it to seal but it is still holding. Probably won't use Stan's next time - too expensive. Link to comment Share on other sites More sharing options...
Thug Posted August 4, 2008 Share My initial conversion to tubeless was pure "ghetto". I used some PVC tape that a mate imports and used that to seal the spoke holes. I then siliconed in a presta valve (with removal core) and filled the tyre with a couple of scoops of Stans. I only changed to a Stans rim strip when I bought my DT Swiss wheels. When it comes time to replace the rim strips I'll probably go the BMX tube route. Link to comment Share on other sites More sharing options...
