Which is better 25c or 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 700×25 28c mean?

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

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.

Do 28mm Tyres need bigger inner tubes?

It’s important to use the correct inner tube width size as much as it is diameter size. Bike inner tubes for narrower tyres will usually fit these wider tyres; they will just be a bit more stretched out to fill the space. They’re unlikely to burst, but if you get a flat they may go down more quickly.

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 is a 28 bike tire?

Tires with diameters 622 mm and 635 mm are both classified as 28 inch. Oddly enough, tires with an inner diameter of 630 mm are classified as 27 inch. These classifications originate from the time of tire brakes. In those days, the exact outer diameter of the tire was defined by the brake.

Do pros use 28mm tyres?

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 28mm tyres more comfortable?

“The most comfortable ride was achieved with the 28mm tyres at a pressure of 5.5 bar: the tyre still having plenty of reserve suspension travel due to its copious volume, while at the same time being barely at risk of puncture,” it says.

Can I use an inner tube that’s too narrow for the tyre?

Yes, you can, as long as you don’t go more than one size smaller, or the differential is not too extreme. A 1.25 in a 1.5 is fine. A 1.25 in a 2.25 is likely to have issues with flats.

How do I choose a bike inner tube size?

The best way to check what size inner tube you need is to look on the sidewall of your tyre. Tyre manufacturers print the size on the sidewalls, so look out for numbers such as ‘700x23c’ for a road bike, or ’26×1. 75′ which is for mountain bikes.

Are 28mm tires slower?
