What do the numbers on bike tire tubes mean?

The first number is the diameter of your wheel. Sizes such as 26, 24, 20, 27.5, 29 and 700c are common tire diameters. The second number (after the X) is the width of your tire. For example, a 26 x 1.75 size means the tire diameter is 26 inches and the tire width is 1.75 inches.

What size of inner tube do I need?

Checking the Inner Tube Size You Need The best way to check what size inner tube you need is to look on the sidewall of your tyre. Tyre manufacturers print the size on the sidewalls, so look out for numbers such as ‘700x23c’ for a road bike, or ’26×1. 75′ which is for mountain bikes.

What does 43c mean?

The Kenda 700×35-43c designation means that these tubes will actually fit 700x35c through 700x43c tires (the 35c through 43c numbers refer to the width of the tire in millimeters and the 700 number refers to the diameter of the tire in millimeters).

Will a 2.125 tire fit a 1.75 rim?

Will A 2.125 Tire Fit On A 1.75 Rim? Though this compatibility is dependent on your bike frame, all things being equal, a 2.125 tire will fit in nicely with a 1 75 rim.

Which is better Presta or Schrader valve?

Presta valves are easier to pump than Schrader, because they have no valve spring to overcome. In narrow rims, clincher tires also leave insufficient space between tire beads for larger Schrader valves. In contrast Schrader valves are more robust, universally used, and have an easily removable core.

IS 700C the same as 29?

29″ (ISO size 622) is actually the same rim diameter as 700C, although most 29″ tires will not fit 700C road rims because they’re too wide. 29″ tires are popular with mountain bikers; search for 29″ MTB. 700C (ISO size 622) is the most commonly used size for modern road bikes.

What size inner tube do I need for 700x40c?

Here it is: pick a tube that matches the numbers embossed on your tire (i.e. “700x40c”). The size of an inner tube varies with the amount of air that you fill them with. So, they’re sold by fixed diameter and range of widths e.g. “ 700×35-43” (which would work for tires ranging from 700x35c to 700x43c).

Can I use bigger inner tubes?

Bike inner tubes will accommodate a limited range of sizes. Larger tubes may be more susceptible to getting pinched between the tire and rim. It’s always best to try and match as close as you can, but there is some flexibility. Having a slightly smaller or larger tube will be quite fine.

How much does inner tube cost?

Common Bike Repair labor rates ​Inner tubes typically cost $8. Specialty tubes (extra long valves, odd sizes, thorn proof, etc.) may cost more. Bikes with internally geared hubs or full chain cases cost more due to extra time, complexity, or component rarity.
