Are 29 and 700C tubes the same?

29″ (ISO size 622) is the same inside diameter as 700C, but some 29″ tires will not fit 700C road rims because they’re too wide. Make sure to check the other necessary measurement, the beat seat diameter. That is also, helpfully, displayed in the ISO measurement on the side of the tire (e.x. 38-622).

Can I use a 29 tube in a 700C tire?

So a 29 inch MTB tube will have the same diameter as a 700c road wheel, while a 27.5 inch tube will be the same diameter as a 650b road wheel. You can also get 26 inch MTB tubes.

Will a 26 inch tube fit a 29?

Valve size is more important than tube size. Take one of each variety (presta/schrader). I’ve run 26″ in 24″ wheels in an emergency with no issues, so 29 in 26 or vice versa will be fine.

Will a 27.5 tube fit a 29 wheel?

No, it’ll be fine. Have you played the innertube-pump-until-it-blows game? 26ers end up like tractor tyres before they let go. Always carry a presta-valved 27.5 tube with me as a spare, can be used for 26/27.5/29 wheels with presta/schrader size valve holes so covers all bases.

What is the difference between 29er and 700c?

So a 700C rim is a narrow rim intended to be used with a 700mm outer-diameter tire. A 29er tire is bigger than 700mm (about 27.6 inches), so the 700 part of “700C” does not really apply. Also, since some 29er rims are wide, the “C” part really doesn’t apply either.

What is the difference between 29er and 700C?

Can I use 26 tube on 700c wheels?

It’s possible to find 26-inch tires that will fit on 700c rims, but a 700c tire will not fit on a 26-inch rim without stretching the sidewalls of the tire just enough to make it fit, especially if you use a tire with especially thick sidewalls.

Can I use 27.5 inner tube 29er?

No problem at all. As with Facian, I carry a spare tube in presta-valved 27.5 flavor for all eventualities. I even temporarily ran one in a 29+ setup without issues. Managed to put a cheapo wrong sized one once on my 29er.
