    Best spare tubes: light, slim, but reliable?

    Like so many I race tubeless but certainly at important 50/100s I want 2 spare (29") tubes. I really don't want to cover 90 miles and DNF for want of a tube, so I'll take some weight.

    Any recommendations? I want them to be as bulk free as possible, and light, but they got to do they job if necessary.

    Also how do most folks carry them? Straps, biggish seat bag, other? (What does Dave Wiens have mounted on his top tube in Race Across the Sky 2009 - curious?) More and more I want zero "stuff" on my body except clothes, lid, and gloves

    Nothing in particular

    I'm also against carrying anything on my body (except a bar/gels)... especially for longer races. I use whatever I happen to have around. Bontrager 29er tubes at the moment. Kyle's strap can cinch down on or two... otherwise a seatbag and strap should cover everything.

    I to use a Kyle's strap. Works pretty well but you do have to make sure you cinch it very tightly. Had some seatbags open up on me so I have found Kyles strap is more reliable.

    I to plan on entering some longer point to point races this season. My plan was to leave tubes with my drops and just carry one tube. I would carry a patch kit just in case. What do others do? Should I carry two tubes?

    What is it they say: LIght, Cheap, Durable. Pick two:-)
    For 100 milers with hours between aid - Carry one spare and big air CO2 with patch kit and tire boots
    For 24 hour lap races (~ 1 hr.- 1.5 hr. laps) - Same as above
    For longer self supported - Same as above plus add another tube and pump. I also have more spares, CO2s available at checkpoints if possible.
    I carry regular 'quality' (continental for example) 26" tubes for my 29er tires that are run tubeless.
    I also like Kyles straps, I put my tubes in a plastic bag just to keep dirt/mud off them until use.

    Is that a typo re 26", or is this some magic trick with some advantage that I'm not aware of?

    No magic, a 26 inch tube will fit in a 29'er tire. Tubes stretch length wise a lot. The are like balloons though, in that the more stretched they are the easier they pop.

    In theory a 26 inch tube would be lighter than a 29'er, and certainly easier to cadge from a fellow rider. Or you could look at it the other way and think that you have more chance of helping out a fellow rider.

    Who knows the only real difference may be the printing on the side of the tube?

    Yes, 26" tubes fit fine in a 29er, I just wouldn't recommend a real lightweight tube and yes, it is easier to help out your buddy on a 26er as a 29er tube doesn't fit so fine in a 26er.

    Yup, in with the others here.

    Carry two, not quite weight weenie, 26" tubes, and you'll be good to go.
