What does 700x25 28c mean?

New Specialized tires have split sizing. So your 700x25/28 tires have the width of a 25c and height of a 28c.

Which is better 25c or 28c?

According to data from https://www.bicyclerollingresistance.com/specials/conti-gp4000s-ii-23-25-28 , 25c at 80 psi is slightly more efficient as compared to 28c at 60 psi and those pressures are in the ballpark area of what I would run typically.

What does 28c mean in tire?

Road bicycle tyres generally come in three widths: 23c, 25c and 28c - this number refers to the width of the tyre at their widest point, in millimetres i.e. 23mm, 25mm and 28mm.

What does C mean on bike tire?

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

What does 700x23 28c mean?

“700” is the overall diameter of the bike tire, measured in millimeters. “28” is the width of the tire, again in millimeters and “c” refers to the width code of the tire (like you'd see when you look at your bike either from behind or in front).

28mm VS 25MM Road Tires - bicycle Tire sizes Explained

Is 28 the same as 700C?

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. This is the most common wheel size, so look out for familiar markings (such as 28x1.

How wide is a 28C bike tire?

A ISO tire size of 28-622 is how we would refer to a 700 x 28C tire has a tire width of 28 mm and a rim diameter of 622 mm.

What does C stand for in 700C?

700C tires

The "700" refers to the rough outer diameter of the tire, although the actual outer diameter will vary greatly, depending on the type of tire and tread pattern. The "C" means NOTHING; it does not stand for "centimeters." Think about it--a 700-centimeter tire would be HUGE, over 21 feet tall!

What does C mean on tire size?

The C-Type tire, on the other hand, is specifically meant as a commercial-rated tire, with a higher load rating for a given size than many LT tires. These C-Type tires will show the letter “C” immediately after the wheel diameter in the tire code. Example: 225/75R16C.

Can I put 28mm tires on my road bike?

Most road bike frames can accommodate a tire as wide as about 28mm. Cyclocross and touring bikes are generally designed to accommodate wider tires.

What does 700x28 38c mean?

700x38c is the size of your bicycle tire. 700 is the nominal diameter of the tire in millimeters. 38 is the width of the tire (as seen if you were looking at your bike from the front/back). C refers to the old French system of classifying wheels according to their Bead Seat Diameter.

Is a 29 inch wheel the same as 700c?

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.

Which is better 700x28 or 700x25?

You will not notice the difference between 25 and 28. Tire pressure and tread pattern are far more significant in terms of rolling resistance, and the difference in diameter/gear ratio is too small for you to feel.

Are 28mm tires faster?

'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 25mm tyres on 28mm rims?

Within the context of current rim shapes designed around rim brake profiles, a 28mm tire matched to a 28-29mm outer width rim (the widest that are currently on the market) just can't match the performance of a 23 or 25mm tire on the same rim.

What does a 28 bike mean?

Meaning Of 28 Inch Bike

The bike has larger tires having a 2-inch diameter, suitable for mountain biking. Most of the American men's frames are between 20” – 24” in height, making a 28-inch bike suitable for them as the measurements are preferable.

A tire size you might see on a road bike:

700x25c indicates a tire with a 700mm outer diameter and a 25mm width.

What does 700x40c mean?

The first number refers to the diameter and the second number is the tire width. On a 700x40c tire, the first number indicates that the outside diameter is approximately 700 millimeters. Tread and tire width can affect the overall diameter, so the 700 is always a rough estimate.

Can I put 28mm tires 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.

What size tires are used in the Tour de France?

As of Friday, four of the six road stages thus far in the 2017 Tour de France have been won on 26mm tubulars. 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.

What size tyres are best for a road bike?

The CTC recommends the ideal relationship between a rim and tyre as being about 1.8 times. Rims measuring 15 to 17mm across are the most common used for road bikes and accommodate tyres ranging in width from 23 to 50mm.

How do you determine bike size?

How do I know my bike wheel size?

Using a tape measure, place the bottom of the tape at the lowest point of the tire (on the ground) and measure in a straight line to the centre of the bike wheel to find your wheel radius (as shown in the image above). Multiply your wheel's radius by two to find the wheel's diameter.

Are 700c and 27.5 the same?

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.
