|   Stan's NoTube Specific questions (double post from general) | spoon
Apr 10, 2003 4:52 PM | | Hey All,
Sorry about the double post but the motivation to go to Stan's is to save some weight so I figured I would post this to the WW's as well.
I have checked out the notutbes website and reviews on Stan's notubes but I still have a couple of questions.
First, I am surprised that non UST tires have enough sidewall strength to hold up to the tubeless life... Any reliability issues, Specifically with the Panaracer Fire XC (2.1) and the Panaracer Trailblaster (1.8)
Second, I would be mounting these to Mavic 517's. I think the instructions say to drill the rim. Is this necessary? and what is the purpose. (I guess is it helps the valve stem seal better?) Frankly, I don't want to drill my rims. can I do it without drilling?
How many rim strips do you have to use? Is it standard rim tape and then the stan's tape? Has anyone applied another layer of tape.
What is the baby powder for?
How does the rim strip seal? DOes that happen when you put the tire on and roll the sealant around?
Thanks for bearing with the long winded questions. If you have any additional tips or suggestions I welcome them. |

Apr 10, 2003 5:13 PM | | First, I highly recommend you do a search in this forum for Stan's or notubes, you will find a wealth of information.
Non-ust tires work great and there are literally thousands of the NoTubes kits out there that people run with standard tires. As for your specific tire choice, I don't know of any problems running them with the system.
As for drilling your rim, all you need to do is to enlarge the inner hole just enough to allow the valve to seat better inside the rim. There is no structural integrity issue. The outside valve hole remains the same size and should you need to use a tube, you'll have no problems with the enlarged valve hole.
You use one rim strip per wheel. Stan supplies spoke tape with the kit to cover your spoke holes and you will remove your existing rim tape. The baby powder is to allow the strip to slide in to position and though not necessary, will make installation easier.
The rim strip creates a seal between the rim and the tire bead that is simply not there if using a standard tire and standard rim. The sealant will coat the inside of the tire to make it air tight and also seal most any puncture you may experience.
Hope some of that helps. Any more questions, just ask. |
| one more question... | spoon
Apr 10, 2003 6:00 PM | | and you have to reapply the sealant every so often?
Thanks for the info, I'll search the discussions. |
| Well this varies on a few variables | TM
Apr 10, 2003 6:27 PM | | Such as the conditions you are riding, if you are getting losts of holes filled in by latex, season etc.
I seem to be having good luck, I havent ever bothered checking to see if it needs a top up. Only time i needed to was when a knob tore of one of my Pythons and alot of latex was used to seal the hole!
* Get the kit you will love it.
* Kevlar beaded tyres are a must IMHO.
* I never bothred drilling the rim, just be sure to pull really tight on the strip when putting the stems in so that it fits in nice and snug! |

I e-mailed Stan a while ago asking him about the reliability issues of using regular tires tubelesshere's what he had to say:
When we mount a tire tubeless it puts more strain on the Kevlar bead. Some brands have a weak bead and are having problems. Michelin is having the most problems and may be the Panaracers I have not heard as much about them. They may be made by Michelin?
I have not heard of any problems with the other brands. When a tire blows off the rim it is either snapping the Kevlar bead or stretching it. This is the only way a tire can blow off the rim.
You should never over inflate a tire mounted tubeless you will notice my instructions say to inflate to 35 to 40 psi and some people are inflating them to over 60 psi. This may cause the Kevlar to snap. Even the Kenda tubeless tires say to only inflate to 55psi and this is a tubeless tire. They do not recommend inflating to 60psi like Mavic says.
The smaller the tire the higher the pressure you can run. If you are using a Kenda Klimax a real skinny tire you can inflate it to 60 psi but the larger the tire the more square inches of surface and this will put more strain on the bead.
Hope that helps. |
