, , , ,

27-inch and 700C tires are close enough in size that the inner tubes are compatible; i.e. you can use a 27-inch inner tube in a 700C tire, and vice-versa. However,

you can NOT use a 27-inch tire on a 700C wheel

, and vice-versa.

Are 27 wheels bigger than 700c?

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.

Can I put 700c wheels on a 27.5 frame?


26 and 27.5-inch MTBs have enough clearance to accommodate 700c rims combined with a tire of an appropriate size

. If the bike and the new wheels are disc brake ready, the conversion will be easier.

Do 700c tubes fit 27?


Yep, a standard 700C tube will fit a 27′′ tire

(and most tube boxes bear multiple markings to indicate this). Just convert the inch width to mm to get the width of the 700C tube, if the box doesn’t say the inch size.

What is the difference between 700c and 27 inch wheels?

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.

Are 700c wheels interchangeable?

The two main options are 700c which is standard for road and cyclocross bikes or 650b, known in the mountain bike world as 27.5′′. Both wheel sizes come with pros and cons making them suitable for different riding purposes and conditions but

in certain respects, the two wheel sizes can be relatively interchangeable

.

Can I put 700c wheels on a mountain bike?


You can put 700c tires on most mountain bikes without issues

. Actually, the rim diameter 29-inch MTB wheels are identical to that of a 700c wheel. So as long as the width of the 700c tire isn’t smaller than the rim width, it will work perfectly on a mountain bike.

Is a 27.5 inch wheel the same as 700c?

That’s changed over the past decade, so the majority of modern mountain bikes now come either with 29in or 27.5in wheels.

These two sizes are equivalent to 700c and 650b wheel sizes expressed in the European ETRTO wheel size designations and have the same bead seat diameters

.

Can I put 700c wheels on a 26 inch bike?

Well, the two are not compatible, and therefore,

you can’t use a 700c tire on a 26-inch rim

. Mostly, the 26-inch tires will have a width of 1.75”-2.2”. However, it is possible to find 26-inch tires that are 1” up to 1.5” wide. Most importantly, a standard 26” tire has a BSD of 559mm.

How big are 700c wheels in inches?

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 IS 700c rim size?


29′′

/ 700c (ISO 622 mm)

The standard modern road bike wheel has an ISO diameter of 622 mm and is referred to as 700c (makes sense, right? /s).

What size tires can I put on a 700c rim?

On a ‘700c’ wheel, you can have a range of different widths.

23mm wide tires

have been the standard for most road cycling over the past couple decades. You might see a 700x20c, or a 700x25c. On a cyclocross bike or 29-inch mountain bike, you could see tires as wide as 700x35c or 700x58c.

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.

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.

Will a 27 inch tube fit a 27.5 tire?


27-5

.

26′′ tubes work perfectly well with 27.5′′ wheels

.

Is a 700c wheel 29 inches?


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. 650B (ISO size 584) is used for some randonneur bikes and other specialized bikes.

Can I put 27 wheels on a 26 bike?


Most 26-inch frames have enough room to accept a 27.5-inch wheel as long as the tires aren’t very wide

Are all 700c wheels the same width?


Tyre widths available for the 700C/622mm size standard vary from 18 to 47mm
