For competitive road racing or time trial you might want to consider the weight, to gain a performance advantage, whilst for downhill mountain biking puncture protection is likely to be your highest priority.

Latex rubber tubes offer slightly enhanced handling characteristics - because latex rubber is slightly more flexible than traditional butyl rubber, the tubes adapt quickly to the tyres changing shape while cornering and on impacts. These are the same valves used on all motor vehicle tyres and are often referred to as ‘car type’ valves. I should note that I weight about 85kg (something like 180 pounds I guess) and as I've been reading for that weight/tube size I should be putting about 116 psi and the tire is rated at 85 psi max.

Suitable for, for example the tyre size 700x23C ETRTO size 19/25-700 and fitted with a 48 mm high Presta valve. Also Latex is more gas permeable than butyl rubber and, as a result, latex rubber tubes do not hold the air as long as butyl based tubes and require more frequent inflation, as well as being fairly fragile and easy to tear when inserting.

Good" hubs and rims, not quality brand though but I've been told they're good and that's what almost everyone in this country uses. Inner tubes are simple but essential – unless you’re riding with tubeless tyres, you’ll always need an inner tube.Another example might be 700 x 18-23c, which seems less obvious but 700c is the diameter of Road, Cyclocross, Adventure Road and Hybrid bike wheels, and the numbers relate to the width in millimetres, so 18mm-23mm wide. The tube needs to fit your tyre to avoid overstretching or pinching, both of which are likely to cause punctures and the tube material needs to be appropriate for your style of riding. Bicycles Stack Exchange is a question and answer site for people who build and repair bicycles, people who train cycling, or commute on bicycles. Suitable for, among other things, the tire size 700x23C or ETRTO size 19/25-700 and equipped with a 40mm high Sclave (French) valve. Please also note that although this listing is for a specific size, all tubes fit a range of tyre widths and this will be evident from the packaging or sizing shown on the tube itself.
