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).

IS 700c the same as 25?

700x25c is the dimensions of your bicycle tire, using the ‘French system’. Let’s break it down. 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).

Is 700x25c the same as 700x25mm?

700c means that the rim has a bead seat diameter of 622 mm. So, 700X25c is exactly the same as ISO 622 X 25. tire. Tires for ISO 622 rims are also called… see more.

What does C mean in 700C?

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. That “700c” tire size has a 622 millimeter bead seat diameter.

Are 700C and 28 the same?

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.

How wide are 25C tires?

Of course, many of the best 23C tires (often labeled 23mm) actually measure between 24mm and 25mm wide when mounted and inflated depending on the tire model and rim size it is mounted on. Likewise, 25C or 25mm labeled tires usually measure 26mm or 27mm wide.

What does C stand for in bike tire size?

The modern clincher rims are Crotchet rims. The letter “C” on a tire’s parameters refers to an archaic French standard for bike tire sizing which relied on letters starting from “A” to “D” to point a tire’s width which in turn translates to the circumference of the corresponding rim.

Will a 700c tire fit a 26 inch rim?

It’s possible to find 26-inch tires that will fit on 700c rims, but a 700c tire will not fit on a 26-inch rim without stretching the sidewalls of the tire just enough to make it fit, especially if you use a tire with especially thick sidewalls.

What is the difference between 700x25c and 700x28C?

Changing the tyre a few mm makes only subtle differences to the bike. Something you may not even notice without a side by side comparison. You should not have any problem installing 700x28C tyres on your bicycle that was originally installed with 700x25C tyres. The difference in width is only 3mm.

What size tire do pro cyclists use?

While 23mm was the pro standard not so long ago, this year 20 teams are using 25mm tires for non-time trial stages, and the other two Specialized-sponsored teams are using 26mm rubber. Continental remains supreme in the Tour peloton, with nine of the 22 squads racing on Competition Pro LTD tubulars.

What is the difference between 700 and 700C tires?

Yes they are the same. 700 is the nominal diameter of the rim. 700C is the usual standard for road bikes, but small frames or some custom builds may use a 650B. 38 is the width of the tyre, in mm, at the widest point.

Are 28C better than 25c?

If you’re a heavy rider, then a 28c tire allows you to use a more comfortable (and often more efficient) pressure while being safe from pinch flats, instead of having to practically overinflate 25c tires. Alternatively if you ride on cobbles, gravel, etc, you can really drop the pressure way down with 28c.

Will a 28C fit a 25c?

Can any road bike tire (23c, 25c, 28C) fit in any rim? No. As a general rule, you can fit a tyre up to twice the width of the rim.

Can you run 28mm Tyres on 23mm rims?

28mm tire on 23mm rim may suffer a bit more. Both aren’t 28mm tire on 28mm or wider rim anyway. Since you don’t bother matching tire width to rim width to begin with, just screw aero and ride what you feel good. No problems.

Are 25 or 28mm tyres faster?

Yes, they are still aerodynamically superior, but the rolling speed advantages outweigh this, certainly at the speeds of regular cyclists and even up to the speeds reached by keen amateurs, even professional cyclists are now running 25mm tubulars and sometimes 28mm for the Spring classics.

Are 28 mm tires slower?

‘Also a 28mm tubeless tyre is the fastest setup [in rolling resistance tests]. At 40kmh a high-quality clincher tyre with a latex inner tube is about 2 watts slower. And a 32mm tyre is only about 2 watts slower than an equivalent 28mm tyre.

Can you put 25 tubes in a 28 tire?

Yep, no problem, you can run them in quite a bit larger tires than that.

Do pros ride 28mm tyres?

For several years we’ve heard of their lower rolling resistance, and experienced firsthand the improved comfort & grip of larger road tires. But pro roadies have been resistant to change. That time for change seems to have come, as 28mm tubulars become de rigueur in the peloton of the World Tour.

What width tires do pros use?
