## What does 700C 25C mean?

Here’s the quick answer: 700x25c is the dimensions of your bicycle tire, using the ‘French system’. 700 is the nominal diameter of the bike tire, sized using millimeters. The next number, 25, is just the width of the tire (this is also measured using millimeters).

## What size is 700 x 25C in inches?

On a 700c wheel, the diameter of the bead is 622 millimeters. This size is sometimes referred to as “29 inch” when it’s on a mountain bike. It can also (very rarely) be called “28 inch”. 25 is the width of the tire in millimeters (writing it as “25c” actually makes no sense).

## What bike tire size is 700?

700c. A standard road tire is 700c x 23mm, indicating a tire diameter of approximately 700mm and a width of 23mm.

## IS 700C the same as 700?

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 size is a 700x25c tire?

700x25c indicates a tire with a 700mm outer diameter and a 25mm width . A third type of tire size might appear on either a mountain or a road tire: 25-622 is the International Standardization Organization (ISO) way of identifying the 700x25c tire in the example above. This system states the 622mm inner tire diameter, rather than the 700mm outer tire diameter, because a key concern is ensuring that wheel size (outer diameter) and inner tire diameter align with one another.

## What is a 700 bike?

The Trek 700 bicycle is a recreational hybrid bike available in men’s and women’s models. Both use 700c wheels, the largest general-use wheel.
