It will fit, but will need to be slightly overinflated due to its smaller size so potentially making it less strong. Perfectly usuable though.

answer 10
Whether or not this will fit depends on the valve type used on your bikes rims. There are 2 main types, schrader (option b is this type) commonly referred to as car type and presta valves. Attached is an image of both types.

There is a 3rd type known as woods or dunlop valves, these are less common and unlikely to be used on your bike if it is a modern mountain bike. You could look up this type of valve if you don't think either of the pictured valves match yours

Yes. If your tyre size is for example 2.2, a 1.75-2.5 tube will fit perfectly. You could also stretch a smaller tube to fit, but this may affect the reliability.

I'd go for the larger in case you upgrade to wider tyres. You are probably less likely to go smaller. Plus you will not be stretching the larger size tube as you would with the smaller.

I believe that either would do and excellent job. The 1.3-1.75 would be fractionally lighter but maybe under slightly more stress.

26x1.3-1.75 will be lighter and 0.00001% faster & smaller so slightly easier to fit but in practice there is no significant difference.

I would say it would depend on if you plan to use the tube with any other tyre and size accordingly. If this is not a factor then I would go with the smaller one on the basis that it would be lighter...

Don't think so. In theory you can put on, but if the tyre is smaller then your rim, it will wear out very quickly.

Question
Presta Valve on Schrader Rim
My MTB wheels are for Schrader (car type) valves, but I got the free Conti tubes for Schrader with the tyres. Trouble is, if I fit them is the hole in the rim for the valve is much bigger than the valve. Any clues? Can you get away with it? Is there a special nut / adapter?
Risks seem to be tube bursting out or dirt getting in.

Yes some Presta tubes come with a screw thread and a nut that has a narrower shoulder on one side that fits into a Schrader hole. Or you can purchase a rubber grommet which fits in the Schrader hole.

If you bought presta valve tubes for a schrader rim, then you bought the wrong type. There is no converter or adapter that I know of. You need to buy the right tube...

answer 3
You've got Schrader valve drilled wheels, and Schrader inner tubes, but the hole is much bigger than the valve? I'd probably get the wheels checked out because all you should need is the securing nut. There shouldn't be too much play in the hole.

answer 5
The Continental Quality MTB Presta valve Inner Tube has a nut with a curved lip on one side. That curved side is designed to fit into various sized rim holes and create a solid seal against the rim. Even though the valve is a Presta the nut should be large enough to seal a Schrader rim hole. However, Continental also do a Shrader valve Inner Tube in this range - do an Inner tube search on the Wiggle web site.

Naah - but if you are looking to use puncture proofing fluids, these valves manage to keep on working once you have put the goo inside.

Getting it inside requires making a small nick in the tube (naah its not actually a puncture that you are making in the new tube - its part of the upgrade!??) and then putting a patch over the nick - making sure that the surface you are bonding to is free of goo.

Then it works like a charm hassle free for quite a long time-Yielding a number of benefits of tubeless tyres without the weight penalty
