Does it matter brand or size RANGE?
I know my tires are 26x2.1 and the rims are cut for presta valves.
Baboons are the same size but Schraeder.
How are Performance brand tubes?

I'd spend a few extra bucks and get the Ritchey superlights or something like that. They save rotating weight (the most important), and they are just as tough as a standard.

I use the Ultralight tubes when I race but train with heavier tubes. If you're interested, I think Performance makes an Ultralight tube.

I like self healing tubes. The make light versions, too. I started using them a year ago nad I've had three flats in that time. (2 where my fault for messing around doing trials with low tire pressure.)

Are you talking about slime tubes?

well, you donīt want to have a too small tube for a big tire.
The tube will have to stretch much more and it will get easier to pinch flat it.

I've found that running a larger tube than specified on the tire helps prevent pinch flats, ie. a 2.3 tube in a 1.9. When you blow up a tire the rubber stretches. The larger the tube in a small tire, the less the material stretches. Stretched material = thin material. I also wrap my tubes with other tubes that are cut up to create an extra layer of material. I've heard that some DH riders will even put a 1.9 TIRE in their 3.0 Tire to help prevent pinch flats.

i think u've all missed the point here. I think MBC is asking DOES SIZE MATTER? yes i know that sounds sick but i meant with tubes....the circular rubber kind.........that go inside your tyre. anyway, if your tubes are 26x2.1 that means your tyre is 2.1 inches wide, the 26 referring to your wheel size (26" is the standard MTB wheel size, but some jumpers and DHers use 24" on the back or both ends). anyway, on the box which the tube comes in it will have the tyre width range which it is designed to be used for, eg it might say 1.95-2.3" in which case it would fit your tyre. the presta valve is the type of valve (i think schrader are car-style and presta are the bike-specific type but it may be the other way round im not 100% sure) and it will say on the box what type of valve it has. if you're buying the tube from your LBS (as opposed to a department store) then the guys there will tell you what you need.

Thanks - I'm aware of all that - I guess what I'm referring to is this: tire size 26x2.1
I've seen tubes for like (for example) 1.95-2.3 range and 2.1-2.5 range - that's what I meant - I should have been more specific. Anyway, I bought the larger ones, and hopefully we will prevent pinch flats based on what some of you said.
Thanks.
