What is a 700C rim?
700C is used to refer to any tire, rim, or wheel with a 622mm BSD, but it could be on a skinny-tired road bike where the wheel has an actual diameter of only 660mm (which is actually a little LESS than 26 inches!), or a mountain bike with a wheel diameter of over 29 inches.
Will 29 tires fit 700C rims?
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.
What size tires fit 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.
How do you measure 700c?
Read the number at the far end of your tire. This should be your diameter. You want to measure in inches for every bike size except a 700c, this would be measured in millimeters. A 700c rim should be 622mm, and measured with the tire, should be 700mm.
