Will a light weight tube work in a 2.3 or even a 2.6 tire?

..........would a 150 gram tube work in a tire that size? Should I expect lots of flats? I am 165 w/ gear doing lots of light freeriding. My present tubes weigh about 350 grams each, and I have had zero problems. Just wondering if I could shed 350 grams in rolling weight.
Thanks for any input.

Any standard weight 1.9-2.1 (1.75-2.35; 1.75-2.5...) tube will work in 2.6 tires and weigh around 200g.

The Kenda Superlight 1.9-2.125 is under 150g and work very well.

The Conti Light 1.75-2.5 at 125g can be more fragile.

Whether they will hold up for you depends on your riding style.

said it before, "this guy knows a lot more than me"

my experience is that the thinner the tube trying to fill my 2.35 kendas, the easier they pop- just like an over-inflated balloon. they explode, and not even slime has been able to do it right.

I used specialized turbo tubes 1.9-2.2 in 2.5's and had no problems. I'm about 190 with gear and ride very agressive and do the easier stunts. But I'm havent used the 2.5's lately as I replaced them with 2.1's.

specialized tubes

so what are you using on the 2.35 kenda's, I have a pair that I've yet to put on?

After having tried the generic performance and pricepoint brands, along with one or two others in teh past year, I have started using the specialized that he mentions below. I knew that the spec. adrenalines (or something) that came on my wife's bike are 2.1, yet are every bit as wide as my nevegal/gluegroove 2.35s.
Knowing that they make their tires with seemingly large air volume, I bought some of their tubes and cycled them in when my slimes blew - and have yet to replace a tube since.
They are just the standard version of their tube, not the condom thin ones.
Hope that helps!

yep

I bought some performance 100g or so featherlight 2.1 tubes by accident and decided to try them in my 2.4 Schwalbe Nobby Nic (actually more like a 2.25) and the only flat I had was due to my cloth rim strip being pushed aside and the spoke holes cut the inner part of the tube.

I've had pinch flats using normal 2.1ish tubes in 2.35 Nevegals over rocky terrain. I think I'm now running Kenda or wtb freeride tubes which are closer to 300g. I know it's probably a pressure issue but I thought I had the tires nice and hard.

I use Conti Lights in all my tires...

Up to a Mutano 2.4 (not really a 2.4), Spec Adrenaline, Kenda Nev 2.35 with zero problems.

Pinch flats... if I'm hitting my rims hard I want to pinch flat. I want to know I need to ride smoother or increase my air pressures. I'd soon fix a pinch flat than keep dinging rims. Tube patches are much cheaper than rims.

Pinholes from thorns and such... that's a different matter. I find them occuring more frequently on light tubes. The Conti Lights are great in that you can unscrew the core in the same fashion as a Stan's rim strip core. I shoot a very small amount of Stan's in the tubes. Since doing this I've yet to flat using these tubes. I'm 180# plus gear and use these tubes on my fully rigid SS and an AM bike. So far the set up has been bombproof. Much less hassle than Stan's and no flats from thorns. I like to change tires out based on trail conditions.

99% of the pinch flats I've had are because I was too lazy to check my tire pressures before riding or because I was riding sloppy. Pinch flats (IMO) are the tire's way of telling you to either up your tire pressure or learn how to ride smoother.

Good comments.
How much Slime do you use for optimal protection and less weight?
How much are these Conti Light tubes with removable core?

So far I've gotten away with about 25cc of Stan's per tube. No thorn flats in the past 3 months since I started using this setup. I started riding some new trails that have too many thorn bushes and for a while there I was getting at least one or two pinholes a week.

BTW, I think I a recent post with this one: where can I get one of those little 6mm to 8mm hex adaptors with the tiny magnet inside? It allows your 6mm on your multi tool to be used on an 8 mm crank bolt.
