Stan's tire and rim sealant?

[emily_in_nc]

madisongrrl,

Do you have any idea how the weight of your tubeless tires + Stan's compares to the weight of a regular tire with a tube? I'd love to learn more about this as a possibility for the future. I am lightweight also and have never had a flat on my mtb (but I'm new to mountain biking). I'd love to get away with not having to carry one of those big ole mtb tubes on every ride!

Thanks,
Emily

The tubeless tires are going to weigh slightly more than the regular tires, but it will depend on your tire selection, the weight of your tube, how much stans you use, if you cease to use a seatbag etc.

I run Kenda Karma tubeless tires and they weigh in at 665g for a 26 x 1.95. A similar tubed tire is the Karma DTC which weighs in at 450g for 26 x 2.00. For the tubeless tire you have to add in the weight of the stans (I use 1.5 scoops of stans with the suggested amount of water), but that is offset by the weight of the tube for the tubed tire set up.

I no longer carry a set bag but I have this special C02 system that attaches to my seatpost.

Your wheelset must be tubeless or tubeless ready to run this kind of set up.

My tubeless is actually lighter (overall) because I don't carry seatbags, tire levers, or tubes. I really like this set up and I have very few worries when I'm racing.

Take care,

Thanks for all the great information! This is something I will definitely have to consider for the future, but right now I've just put nearly $2K into a used Titus Racer X plus repairs and new crankset, so I don't see a new wheelset in my immediate future, but perhaps down the line. I love the idea of not needing to carry a seat bag and being able to run lower tire pressure. Since I only weigh ~105 or so, I tend to run lower pressure anyway, so I figure a pinch flat could happen eventually (but I'm willing to risk it until it actually happens!)

Thanks for your informative, thorough explanation!

Hey Madison Girl, the question you haven't answered is have you actually flatted with the Stans?

I run tubeless without Stans (my Kenda sponsor says not to run the Stans -- it ruins the tires). Of course, that means a traditional flat change (and as you know, tubeless are a butch to get on & off the rim).

Nope I haven't flatted yet. But for my friends who have flatted, the stans held up pretty well. It is almost amazing what that stuff can do (provided that you don't have a huge tear in your tire) I know there are a few pros (like Mary M.) that run stans with their Kenda tires as well as many people I race with that have used this set up. So that is why I went with the Stans even though Kenda said not to.

I haven't had a problem getting my Karmas on and off the rim. It is actually much easier than the taking the stock tubeless Michelin tires (which had tubes in them) that came with my Trek Fuel EX 9 on and off the rim. The fit was so tight that I couldn't do it....When I went in for a fitting and needed to put a slick on, I had the guys in the shop take that tire off and on for me. It took them 10 minutes to get that tire off and 10+ to get it on (and this is a high end, well experienced shop....not the typical LBS)....and they had to used brute force with one of those salad tong tire tools. So I decided to drop the tubes, buy the Karmas and use the stans. So far so good...so we will see!

Great info, thanks! I will pass this information along to my mtn biking DH

Velogirl,

Do you race expert or are you a pro? What type of mt bike races to you enter?

Tubeless mountain bike tires. I've never run tubeless but have been told by many of my male racer friends the reason they run them is that they can run less air pressure which makes their bikes stick to the trail easier, without the fear of flatting as much as with tubed tires. You have to run more air pressure depending on heavier riders and type of rider if you are a basher and heavier, you need more air pressure, hence the reason they want to run tubeless. They still can flat and if you are by yourself, you should carry a tube in case you can't get the tire to seat again or it has a cut in it or something like that.

I never wanted to spend the money on them cause 1. I rarely flat cause I'm not too big; 2. I rarely flat cause I'm a cautious downhiller; 3. I only run 35-40 pounds in my mountain bike tires anyway. So, it is a personal choice I guess and there are a lot of variables into why you might want to run tubeless vs. tubed.

I raced several seasons in the Arizona desert and never flatted (even with cactus thorns everywhere) with tubed tires. The only time I even run slime is when I do 24 hour racing and that is because there are lots of thorns on the trail from people running into cactus at night! And, they are hard to miss when you are riding at night with lights.
