    Q-tubes superlight question

    I would like to replace my tubes with something lighter when I replace the rim strips on my Fatboy 24.

    The Q-tubes Superlight only come in 24 x 1-1/8 inch

    Q-Tubes Superlight Tube (24 x 1-1/8 inch, Presta Valve) - cyclesmith.ca

    Would these work in my 24x 4" Ground Controls? I'm a small female rider and I ride almost exclusively on snow at about 3 - 4 psi.

    If you really are looking for 24s then I would look to specialized. They have a 24 2.4-3.0 that somewhere I saw weighted in at 235g. They are a bit more expensive but they should be trouble free. And they will for your 4" tires.

    Which Q-tube or Specialized tube can be used for the Ground Control 4.6" tires?

    I recently put in the Surly Ultra-Lights but have been thinking about going a little lighter yet on my tubes.

    Try a different store. The Q-tubes lites you want are these: Bikeman Q-Tubes Super Light 26 inch x 2.4-2.7 inch 32 mm Presta Valve Tube

    I used these for years until I went tubeless. Got lots of flats, I have to say.

    The OP has the Fatboy 24...meaning 24 inch wheels.

    She doesn't need 26 inch tubes

    OP, i found these on the Jenson website, not SL, but likely still lighter than what you have now:

    Q-Tubes Standard 24" Presta Tube > Components > Wheels, Tires and Tubes > Tubes | Jenson USA

    I wouldn't run the 1 1/8 tubes you mentioned.

    Yes, I do need 24" not 26" tubes.

    Thanks, I thought the 1 1/8 might be too much of a stretch. Is there anywhere I can find the weight for the standard Q-tubes?

    my trusty updated Q catalogue sez 246 grams for the 24 x 2.4-2.75 standard schrader valve (only). retail about 6 bux. prolly half of what a special-ed toob sellz for.

    I think I'll still go with tubes for now, but what size tube would I use for 24" tires if I did want to go the split tubeless route?

    I use the Q Tubes 24" tube for split 26". I'm not sure how well a 20" would work. Maybe a 24.

    Go with the 20 inch tube. The 24 inch tube will be too loose fitting.

    Universal Cycles -- Q Tube - Presta Valve

    Get the widest one they have, which at the moment is 20"x 1.75-2.125" 32mm PV.

    Check out Schwalbe tubes. I bought 4 tubes for the 26" wheels and they all ran less than 190 grams. I ended up going to schraeder valves in case I decided to add slime.

    Tubes have held up even with the light weight.

    Q-tubes superlight question

    Why not do regular tubeless, not the split tube. At 24 inch tires, the gorilla tape method is quite simple.
