DeanS replied to the topic Re: Tjoopliss Conversions... Awesome or Awful in the forums.I've used Stans, ghetto, and also using just a rimstrip in one of my tyres, with a stem taken off a road tube, which is the only non stans still running.
Stans is the best, sealant and strips. The ghetto conversion worked well, but getting a tube with the removable core is a shlep, I used to be able to get Conti tubes, but no more.
Whichever way yougo, it's worth it.

Bigben replied to the topic Re: Tjoopliss Conversions... Awesome or Awful in the forums.I have also gone through almost all 'versions' of tjoopless anad here is my take:-
1) ghetto - cheapest, easy to do but have yet to find tubes with removable cores freely available, have a set of wheels running for 3 years on the same conversion no problem - not so easy to inflate without a compressor
2) Stan's/Joe's - much of a muchness between the 2, find that over time the valve to strip 'attachment' becomes weak and eventually breaks. Solved that by using the 'stand alone' valves with the damaged strip no problem - not so easy to inflate without a compressor
3) Bontrager 'hard' plastic strips - don't fit all rims, have trimmed them to work though (painstaking ....). Tyre generally fits pretty tight so inflation is generally pretty easy (even hand pump)
4) BBT Green plastic strips - mixed success, fit all rims that I have tried them on. Tend to crack at the valve hole very easily. Have had 3 replaced because of that. 1 set of wheels with them working fine.
5) New rubber strips (26 & 29") name escapes me - easy to fit, tyre pretty tight and easy inflation. (NB busy trying out their road tubeless) - WILL CHECK the name tomorrow
Have tried all sorts of sealant but always end up back at Joe's - the worst I have used was OKO! Have some Zero Flats at the moment, will try it out soon.

patches created a new topic Tjoopliss Conversions... Awesome or Awful in the forums.Not too long ago I was in the market (meaning I got 5 punctured in 4 days of riding) to convert my 4X bikes whees to tubeless. Being the scrooge that I am, I did my research on which strips, sealant, technique works best.
I asked the experts (those with 4 or more bikes running tubeless, hahaha)... Here's what I gathered...
Rim Strips:
Stans - work well... pricey
BBT (the green ones) - cheaper... but too plasticky, premoulded shape wont work with all rims and generally crap
20" BMX Tubes - cheapest of all, but work like a bomb! (my choice)

Bigben replied to the topic Re: Endless Tubeless Woes ... can anyone help? in the forums.Ah krasavitsa!
I have had quite a few problems with the green strips, they tend to crack where the valve tightens against them and then won't seal properly, I have in fact changed to the rubber ones and now have no issues!
I have also had issues with sealing of Rocket Ron EVO tyres :(
Here's BigBen's power tip just for you .....
Take the wheel off, pump it lekker hard (50PSI) then dip it in a pool (or other big enough water feature) till you find where it leaks.
Based on that decide what to do, if it leaks at the valve then best to remove the tyre and check the strip. If it is cracked insist on getting it replaced (they did replace mine)
If it is just leaking through 'pin' holes on the sidewall then just make sure sealant gets to there as it most likely won't easily while riding.
The pool test is best cause you can find out exactly where the problems is!

LeighM created a new topic Endless Tubeless Woes ... can anyone help? in the forums.Ola dear Comrades
So I have the most awesome bike in the world now, BUT endless tubeless woes are making me reluctant to go out and driving me to the edge of sanity. Tears were not far today, not that crying would help, but I'm sooo frustrated.
I have Rocket Ron tubeless ready with green strips and use zero flat sealant. If I ride on weekend, by Tuesday or Wednesday one (or both) tyres will soften. Am on the verge of burning them and finding my cheap bike's tyres with it tubes and putting them on instead in sheer desperation.
So Comrades can you help with the following:
* what am I doing wrong?
* how often long sealant last (I know the answer's probably how long is a piece of string)?
* I got a new rocket ron tyre last Wednesday it was sealed and set and lasted the 72km that I did at the 24 hour but by Monday morning it had lost pressure? I was told today that it may be that I don't ride enough for the sealant to get into the all the "nooks and crannys" and then the air leaks out and the ammonia in the sealant evaporates so come time for my next ride tyre's flat, sealant is dry and my woes start over - truth? or just tell the customer something cos we have no idea why?
* Is this just how life is with tubeless and I must just get used to it, buy a bottle of sealant replace it each week and buy a years supply of bombs to inflate the tyre - cos I seriously never had this much hassle with a R3k bike and tubes?
* I see Linden Cycles & FPC have some black rubber strips - should I replace the green ones with these (although the ones I have in now are only 1 week old) - apparently there have been some issues with them cracking or not sealing fully - anyone had that experience?
* How can I make these work until it comes time to replace the tyres?
* When that time comes what should I get?
Thx Comrades, please help me get back on the dirt, with confidence and a sense of reliability.
