To tube or not to tube???

Anyway, just convert them to Stan's.....you'll appreciate the advantages

EDIT: wonder if the fact you run rim brakes has something to do with your tube issues? Also what kind of tubes are you running?

My initial question on 4/23 @ 6:23A about Kenda tires was referring to their use with Stan's.

Regarding the wierd problem - I'm running the same Mavic 217's since 1995. I've never had this kind of problem, ever. I'm currently running standard Specialized tubes. Not the super thin Turbo, just the standard thin. Maybe it's caused by too much talcum powder, or talcum on the bead. I'm now running the lowest pressures I've ever run, so maybe it's easier for the tire to spin on the rim. I always center the valve with the label on the tire, and haven't noticed if it has moved. I need to mark the tire in relation to the rim and see if the tire itself is spinning.

I'd like to convert to Stan's, but I don't know what to think about the use of the sealant with Kenda's.

Yeah I know what you've probably read about using Stans with Kenda tires. I've been using it for a good year now and have had ZERO issues with it. I think as long as you don't let the sealant just sit in one spot you'll be ok. You'll probably spend enough on tubes throghout a year to just get new tires once a year anyway if you're really worried about it. I've converted a few members on here into using Stans and they are all very satisfied.

I would be one of those guys. The ride w/o tubes is a lot more supple has better traction. By the time the sealant eats away your Kendas (if it even does) your treads will be worn. I have no experience with the rimstrips but they work fine on 819's.

I've also dranken the Kool-Aid, I just got sick of pinch-flatting. I feel much more confident now going over rocks and other obstacles knowing that pinch-flatting is not an option anymore...I think everyone I've ridden with has waited for me at least once because of a pinch-flatted rear.

Every time I park the bike, the sealant will sit in one place. Let's just say I'll only be able to ride once week, would that a problem?

*exit to garage to check valve stem*
*return to laptop on couch*

OK, I just checked out the tire. It appears the tire is actually slipping on the rim. I had the valve stem centered between the two words "Blue Groove", and now the stem is centered on the word "Groove". This means the tire is spinning on the rim when I am braking. Again, this is something I have never experienced ever. I did just recently switch to the Kenda Blue Groove and the Nevegal, but I don't think I experienced this problem on my first run on the front tire. I'm hoping a good cleaning of the interior wall of the rim and bead of the tire with denatured alcohol, and then being extra careful to keep the talcum off those surfaces, would keep this from happening.

However, this brings up a possible problem when converting to Stan's. One of two things will happen. The rubber strip and the sealant will lock the tire to the rim, or the tire will continue to spin on the rim and unsealing the bead to the strip.

Even if you only ride the bike once a week you can go out to the garage and spin your tires at least once in between. But really I don't think that is even necessary being that I have 4 bikes, 3 of them converted to Stans and obviously I don't ride all of them every week so they just sit for longer than a week and I haven't had any issues.

There is no chance that your brake pads are coming into contact with the sidewalls under dynamic conditions is there? Either way I think that problem would go away once you converted to Stans. The bead sort of "glues" itself to the rim strip and I really don't see it spinning on your rim after that.

No contact at all. I've put enough miles on the tire that I would have destroyed the sidewall if that were the case.

Either way, I'm saving for a new wheelset so I can run disc brakes, but that's a different thread.

UPDATE -

I cleaned the bead and inner wall of the rim with denatured alcohol. Same story. Is it because I'm running too low of pressure? The gauge on the pump says somewhere around 30 to 32 psi.

Hey guys

I use to be a fan of Stan's No-tube kit....well I'm still kinda is. But those rubber rim strips cost 25 bucks each? They can't possibly cost that much to make. So I found this $5 dollar rim strip from Maxxis and guess what they are way better!!!! Don't get me wrong I still use stan's sealant but I'm running Maxxis rim strips now.

Here are the reasons why:
Cheaper..wait make that wwwaayyy cheaper. $5 compare to $25
It rises over the rim so extra rim protection
it has it's own bead hooks to get better sealing action so it inflates really easy and a lot faster than Stan's rim strip.
Because it seals better the tire is less likely to POP off the rim.
Works a lot better on narrow rims...717..317..dt4.1
Did I mention it's only 5 buck per wheel?

Make sure you get the right size for your rim.
