    29er inner tube

    I'm starting to ride longer distances now so really need to start carrying a spare inner tube. Any that you can recommend?



    Thanks.

    Price is not too much of an issue at that price. Are there different size tubes for 29ers? I have a Felt Nine Sport.

    1.9-2.3
    Put your glasses on so you can see what I'm talking about.

    Look at your tire, the size it should be on the sidewall. There is generally
    A size range that the tubes can accommodate, and even then you can color outside the lines a bit. Ex: I used 26" tubes in my old 650B (27.5") wheelset

    Ok, keeping that in mind head down to your LBS and tell the monkey behind the counter that's what size TIRE you have. Double check the box, the trained monkey gives you, if the size is within reason, pay said monkey, then turn around and leave.

    That's it, congratulations on your first tube.

    Good luck with your 1st flat....

    as far as recommendations, all tubes are pretty much the same. whatever the LBS has is probably just fine. just get the right size range and the right valve- presta or schraeder.

    I just patched my original tubes that were schrader. I am running prest with adapters. The original tubes had pin holes from cacti and thorns. Put a couple patches on and good to go. At least back to the trailhead.
    I also carry a patch kit.

    On my rear 29er 2.0 The Captain I run an ultra light 26" tube which saves 45grams of rotational weight.

    Went to my LBS and gave him my tyre measurements. The one he gave me looked too thin but he said its fine as they blow to different sizes. He saw my bike out side at this point. I get home and pump it up and the tube is so thin its for a road bike

    My current inner tube is 29x1.9/2.3. What does the 1.9/2.3 bit actually mean?

    That's the tire width range in inches. Walmart has them.

    Carry two spare tubes and a pump.

    26x1.9-2.3" tubes work just fine in 29" tires.

    29 x 2.2 Kenda Karma tires.

    Before I went tubeless, I ran 26 x 1.5-1.9 tubes. Had to stretch them a bit over the rim, but no issues, and no more frequent flats than "29er" tubes.
    My "carry tube" is some sort of 26er presta tube. I call it the "Type O Negative" tube. If you need to loan out a tube to a fellow rider, it doesn't matter if they're riding a 26er, 29er, presta or schraeder. It'll fit at least good enough to get them out of the woods.

    Some recommended running tubeless. If you are not, you should. You WILL still need to carry the tube though!

    I recommend a cylcocross lightweight tube size 35. It will pack smaller and works just fine on 29er.

    The 26" tube will also work, but can be a real PITA to get on a 29er wheel.. It took me and a buddy about 5 minutes trying to stretch the 26" tube out just to get it to fit on the rim last time...no more of that...

    Beat me to it, and awesome image.

    26" tubes are better because they fold up smaller and stretch out to fit in a 29er wheel and are more convenient if you have multiple bikes with different sized tires.

    I've even used a 700x35 tube to limp a 26x2.1 tire home, not ideal as there was a serious lump near the valve stem but worked for a few miles of slow speed riding.

    Tubeless is not a cure all. When I need maximum reliability I use tubes.

    Takes me maybe 20 seconds longer to install a 26" tube than a 29".

    Agreed about the tubeless thing...that is why I said to always carry a tube.

    About the 20 second longer install, what is the trick? The 26" is so tight that it gets in the way of the bead lock system.

    This is why it needs to be stretched before imo..

    Some air in the tube for shape. Start at the valve. Tuck in the tube as you mount the tire bead.

    What do you mean by bead lock system? These are not motos or rock crawlers.

    Dont listen to those saying to use 26er or cyclocross tube.
    By that reasoning you could use a 20 or 24" tube in your 26" bike.
    But you wouldn't.

    It is a 29er.
    Use 29er tubes if you are using tubes all the time.
    26er tubes will work for a emergency to get you back to the car.

    29er tubes are easier to mount up. 26er tubes do work just fine however. Just looked at my riding stats and 26er tubes put in 5,884 miles getting me back to my car before I switched to tubeless.

    My 29er came with Kenda tubes, and both failed during the first 50 miles. I got some Forte 29er tubes on sale, so far they've held up better.

    Which were likely made by Kenda.

    Kenda tubes are generally very reliable.

    I'm guessing you're one of those guys that asks what 29er cranks to get for his bike?

    Tubes are tubes within reason, they stretch out a ton. Ever see the 'lightweight' tubes at the shop? Those are just undersized tubes. In order to shave a little weight (and $$ compared to lightweight tubes), a lot of people use one to two sizes smaller of a tube. I've always run 26x1.9 or 26x1.75" tubes in 26x2.1-2.3" tires, 24" tubes wouldnt be bad except that its hard to find Presta valve 20" and 24" tubes.

    Most of us arent necessarily recommending using a 26" tube all the time, but just to carry one as a spare since it'll back smaller in a saddle bag or Camelbak than a full sized 29er tube.

    The lightweight tubes I have are the same uninflated width as the standard tubes. They use thinner walls, which also tends to let them expand more than a thick wall tube. The pic I posted is an ultralight 26x1.9-2.3" tube.

    Interesting. My only experience with lightweight tubes has been with road tire sizes and they all have seemed significantly smaller than a standard 20-25mm tube.

    Look at the Maxxis site
    Tubes
    Gives the tube wall thickness in mm.

    Ok, Ok, Ok... Congrats! Shiggy is the winner! Your response got me to post my first post... I too am convinced that the 26" tube will work fine in the 29" tire! Seeing is Believing :-)
