What inner tube do I need? (Sorry for sounding thick)

Bonkleg

Hi 

Forgive my naivety but I I'm not sure what to buy I have a Giant Talon 2.5 ( http://www.giant-bicycles.com/en-gb/bikes/mountain/3682/35817/)
and the wheel diameter is 26" I'm not sure what you mean by presta and schraeder.

I have looked on wiggle  http://www.wiggle.co.uk/p/cycle/7/Continental_Quality_Pack_Of_10_MTB_Inner_Tubes/5360025966/ and Im not sure what to buy?

Thanks

Presta and schrader are the different types of valves on the inner tube. Schrader being the same as the one you will have on a car tyre.

Just match your tubes to the measurements on your tyres which will be 26 x.....

Spare tubes i have are 26 x 1.75 up to 26 x 2.10 fitment

Hope that helps?

Just to explain a bit more, the first number is the size of the wheel so 26" is for a 26 inch wheeled bike (most MTBs) and 700c will be for road bikes.

The second number is the width of the tyre that the tube is designed for. They'll normally have a range, like 1.5"-2.0". So it's best to make sure that the tube range matches with your size of tyres, although it's not particularly critical. If the tube is a bit small, it'll just be more stretched and will be slightly thinner as a result. Likewise, if it's a bit bigger, e.g a 2.25"-2.5" tube in a 2.1" tyre, it'll be slightly thicker, possibly giving better puncture resistance, but at the cost of a little more weight, but it's not really a problem.
