How do I choose the right size tube?
Step 1: Picking the Right Tube Size
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. The range for widths is usually between 1 and 3 inches.
How do I know what size tube my bike needs?
What size wheel is 700c?
All road and cyclocross bikes are built with 700c wheels, which are 29 inches . However, 700c wheels are designed to accommodate a thinner tire. Many come in widths ranging from 18 to 23 millimeters, with touring tires ranging from 25 to 28 millimeters.
What does 40c mean for bike tires?
700′ is the nominal diameter of your tire, measured in millimeters. ‘x’ just means multiplied by. ’40’ is the second number and is the nominal tire width , also measure in millimeters. ‘c’ is the identification code (from the old French system) for the tire width.
IS 700c the same as 28?
28”/700C/29er
The tyres can differ, but the 28”, 700C and 29er are all the exact same rim diameter . The 700 markings will be followed by the width in mm, and the 28 or 29 markings will be followed by the width in inches. This is the most common wheel size, so look out for familiar markings (such as 28×1.
IS 700c the same as 26?
What Is The Difference Between a 26 Inch and a 700c Wheel? This brings us around back to the same answer; they are the same diameter, but a 26-inch tire will fit onto a 700c rim but not the other way around because of the difference in rim thickness .
Is 622 the same as 700c?
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.
Will a 27.5 tube fit 700c?
However, tires that are close in bead diameter may use the same inner tube. For example, an inner tube for an ISO 630 tire (27-inch) will also fit an ISO 622 (700c) tire . The inner tube should also match the tire width, but, because inner tubes are elastic, one inner tube may fit a range of tire widths.
Will a 29 inch tube fit a 700c?
And 29-inch wheels are the same size as 700c, though they’re usually wider . Kids’ bikes will have smaller wheels, usually 16in, 20in or 24in, and need smaller diameter inner tubes and tyres, as will most folding bikes.
What does 700c mean?
700c is the size of your bike tire , according to the ‘French system’. The “700” number is the stated diameter of the bicycle tire in millimeters. “c” is the width code of the tire (as you would see if you looked at your bike from behind or in front).
What does 700x28c mean?
700 refers to the diameter of the wheel. Almost all road bikes have 700c wheels on them. 700x28c means a 700c tyre which is 28mm wide . 700x32c means a 700c tyre which is 32mm wide.
Can I use a bigger tube in my bike tire?
Yes, it’s perfectly safe to use the next larger size tube in a smaller tire . It’s a common trick used by bike messengers to reduce the chance of flats. The only downside is a slightly heavier wheel since you’re using more tube that you really need.
What do inner tube sizes mean?
The size is almost always written somewhere on the sidewall of the tyre. Inner tubes typically state a wheel diameter and width range for which they will work , e.g. 26 x 1.95-2.125′′, indicating that the tube is intended to fit a 26 inch tyre with a width of between 1.95 inches and 2.125 inches.
How many inches is 700c?
The simple answer is that 700c equals 27.5 inches but, unfortunately, it’s not as simple as that.
How wide is 40c?
Relearning Our ABCs
First of all, what the heck does the C stand for? You’d be forgiven if you thought it was some abbreviation for a metric measurement, since the 700 represents millimeters, and a 40c tire is supposed to equate to a 40mm wide on certain width rims.
Can I put 700c tires on a 29er?
You can indeed fit a 700C tire on a 29-inch rim . All you have to do is avoid using an old-style rim with less than 16 spokes per side and your tires should just fine. It is the same size, so you can fit a 700c tire on a 29-inch rim. It will be a little too wide for the rim of course, but it should work.
Is there a difference between 700 and 700c?
It doesn’t mean anything, really. It’s a historical relic. At one point in time, “700c” was a standard tire/rim size, where “c” indicated the bead seat diameter and “700” was the diameter, in millimeters, when the tire was installed and inflated.
What is the difference between 29er and 700c?
A 29er tire is bigger than 700mm (about 27.6 inches) , so the 700 part of “700C” does not really apply. Also, since some 29er rims are wide, the “C” part really doesn’t apply either. So a 700c rim can be used to build a 29er wheel, but technically speaking not all 29er rims are 700C (if you use the real definition).
Which is bigger 26 or 700c?
A 26 inch, or a 650c wheel is about 1 inch smaller (about 2 inches smaller with road slicks) in diameter than a 700c . On smaller bikes, that 2 inches is a big help in building the perfect size without sacrificing performance.
Which is bigger 700c or 27 inch?
The rim diameter of a 700c wheel is actually slightly smaller than that of a ’27inch’ . 700c bead diameter is 622mm whereas 27′′ bead diameter is 630mm.
Is a 27 inch wheel the same as 700c?
Registered. It’s not really a big issue. 700C wheels have a bead-seat diameter of 622mm, for 27′′ it’s 630mm . 8mm difference in diameter is 4mm radius, so if you put 700C wheels on a frame designed for 27′′ the brake needs to reach 4mm further — less than 1/4 inch.
