Is 29 Inch The Same as 700C

Is 29 Inch The Same as 700C?

A good number of newbies and even seasoned bike riders ask, is the 29 inch the same as 700c?

Is 29 inch the same as 700C

I’m glad I wasn’t the only one who didn’t know the answer to these questions.

When it comes to racing bikes, fat bikes, modern road bikes, or even touring bikes, a majority of us get lost on the tire sizes, rim sizes, or the basic wheel diameter measurements.

There are just too many sizes to work with, it can be overwhelming. In this article, I will try to explain the sizes in the simplest form possible, go through the common sizes across the globe, look into wide tires, ISO sizes, and other road bike and mountain bike wheel sizes. 

Basically, we are going to try and unearth the range of sizes that bike shops will have as we try to understand the difference between a 29 inch and a 700c.

29″ is the same as 700C…

29

…and 27.5″ is also the same as 700C.

A 29-inch wheel would be the same as a 700C wheel, but not vice versa. A 700C tire will fit on a 29-inch rim – without any adjustments necessary for width and casing length.

A 29-inch wheel is the same as a 700C wheel. In fact, a 29-inch tire will fit on your 700C wheel without any fiddling with either width or length. The only exception is if you’re using an old-style rim with less than 16 spokes per side. Then you might have to do something about it.

Here are some notes to have:

  • 19.5″ is not the same as 700c. It is 19.5 x 2.
  • Is 27.5 the same as 700C? Again, it is 27.5 x 2

So, is 700C the same as 29? Answer: 700C x 2.

Confused? Let’s dive in deeper.

Where there’s wiggle room is with the measurement of tires. In the case of tires, all three sizes can be made in a certain range for either width or length.

But if you are ever unsure, go with the bigger measurement of any given tire size (width or length). It shouldn’t be a problem and it will give you more room to play with if you find an ideal fit around your rim tape (aka inner tube).

Do whatever you desire, but if it doesn’t fit just right around your rim tape – then don’t try to force it on.

Being the case, will a 700C fit on a 29 inch rim, and is a 700C tire the same as a 29 inch? 

Yes, if the tire is of a wide enough width for you to still have your 4-6 inches of space between the tire and the rim. And no, if you’re using an old-style rim with less than 16 spokes per side. Then you might have to do something about it.

If you are ever unsure whether or not your tires will fit properly over your rims, then make adjustments accordingly for width and casing length (which in turn affects overall length).

If it doesn’t fit just right around your rim tape, then don’t try to force it on. Perhaps the most obvious one is, “Is a 700c tire fit on a 29-inch rim?” 

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. You might have to turn the tire sidewall inwards a little to make sure that there is enough rubber exposed on the inside of the tire.

But with some effort, you can use 700c tires on 29-inch rims.

Is 27.5 Same As 700C?

No, they are not interchangeable sizes because a 27.5 inch is a wheel size and not tire size.

A 27.5-inch wheel has a 650b hub (this would include the Schwalbe Lugano and Kumho Spirit, which are 26-inch wheels).

A 700C rim can be used on a 27.5-inch wheel, with a conical spacer (which may not be necessary, but to be extra sure). 700C rims are 25mm wide whereas 700/27.5/650b rims range from 22mm to 23mm wide.

Is 29 inch the same as 700C?​

is 29er same as 700c

It depends on where you ride. If it’s a mountain bike, probably not. However, if it’s a road bike or other “all-around” bike (ie., not a mountain bike) – they can be used together with little problem.

Usually, just be sure to tape up the tire sidewall so that there is enough rubber exposed on the inside to keep from rubbing against the rim.

Will a 700C Tire Fit On a 29 Inch Rim?

Yes, but a 700C tire is really wide for a 29-inch rim. It might even rub against the inner sidewall of the rim when you turn.

Will 26×2.0 fit on a 700C rim?

Yes, 26 x 2.0 will fit on a 700c rim, just be sure that the tire is centered on the hub before inflating to make sure that it does not rub against the frame or fork when turning due to overinflation.

But it will probably be too wide for most standard 700C rims unless they are labeled as track or semi-slick tires (where wider tires are almost always required).

Is 29″ The Same as 700C?​

I’m using a 700c wheel with a 26″ rim. Will regular 26″ tires fit on it instead?

Most 26″ tires will fit on your wheel, as long as you don’t have to center the tire over the hub. Check the rim for clearance before buying any tires (external rolling resistance is less of an issue for wider rims).

But I want 27.5 instead of 29! Is that even possible?
Yes, but it is not something most people would notice unless they were to ride a large race tire or something “really fat” (think XTR/XTRD 28-32mm widths).

700c vs 29″ vs 650b vs 26″

C and 650B (27.5) rims have a slightly larger diameter than 700c rims. This means that the 27.5-inch wheels require different hubs, and usually different brakes, which were made to fit 700c wheels.

The main difference between a 26 inch wheel and a 700c wheel is that the 26-inch wheel has a 559 mm diameter while the 700c rim has a 622 mm diameter, resulting in a wider tire footprint.

A 26-inch tire can fit on a 622 mm rim, but it will be just slightly too small to grip the rim correctly. A 27.5 inch wheel is a midway size between a 26 inch and 29-inch wheel.

In comparison to 26 inch wheels which have a 559 mm diameter, 650b (27.5) wheels have a 584 mm diameter.

A 27.5-inch tire can fit on a 622 mm rim, but if you are using the minimum amount of air in the tire, the tire will be very tight on the rim and may not grip properly when cornering or riding off-road.

So, is 29 inch the same as 700C?

No! 700c is not a size for wheel nor tires.

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.

Again, will a 700C tire fit on a 29″ rim?
Yes. There are also companies who make (or make available) a 700c/29-inch tire. A 700c tire or one of similar diameter will fit on an “ISO” (International standards) 28-29/700C rim without any modifications (again, this is for an equally-sized 700c/29″ tire).

You can however convert your current tires to 29 inches.

FAQs about 29″ wheels, 27.5″ wheels, and 700C wheels

Why is 27.5″ not the same as 700C?

North American tires are not all created equal. For example, the “potential” diameter of 26 x 2.0 UST tires are larger than 26 x 2 UST tires.

How do I buy the right size tires for my bike?

Getting the correct size tires to fit your rims is one of the more confounding parts of riding a bike, in part because of the lack of standardization in how tire sizes are described.

What is ISO tire size?

The ISO tire size is described by two numbers, the first of which defines the nominal width of the tire in millimeters, and the second defines the diameter of the tire at the tire bead (the inside edge of the tire), also in millimeters.

What is the ISO size for a tire?

The image to the left shows an ISO size 25-622, a 25mm tire with a bead diameter of 622mm.

What is the difference between the nominal size and ISO?

It gives you a sense of relative size, but it doesn’t tell you if a given tire will be compatible with your rims.

What is the 700C Tire?

A 700C tire would have the smallest width and volume, while the 700A would have the largest..
