May 30, - We explain what to look for when choosing bike tires for commuting. The casing is made from either nylon, cotton or silk and measured in 'threads per inch' or 'TPI' The most common road tires widths are 23c, 25c and 28c.
My road bicycle has 26 inch wheels, and my top gear is inches.
If I have a inch gear, and I'm pedaling at a cadence of 90 revolutions per minute, I will be traveling forward at about 31 miles per hour no matter how big my wheels are Foad are a few standard gearing patterns that are used for c 28 inch road bike tires 26 inch road wheels.

In store special! What do the various size markings on bicycle tires mean?
What is actually the difference between 28 and 29 inches? What are the advantages of the new wheel sizes However, older English and French tire size dimensions are still used as well.
The ETRTO size specification indicates the width of 37 mm and the tire inner diameter westminster massage places mm. This dimension is clear and allows a precise classification of the rim size. Inch sizes are not precise and lack accuracy.
For example, diameters mm MTBmm Triathlon and mm Touring are all classified as 26 inch. Tires with diameters mm and mm are both classified as 28 inch.
Oddly enough, tires with an inner diameter of mm are classified as 27 inch. Leigh holds bachelor's degrees in anthropology and linguistics from the University of Washington.
At first glance, it appears that the difference between a inch wheel and a inch wheel is just 2 inches of diameter. However, the difference in size is rarely exactly 2 inches, due to varying widths and depths of the tires used.
In addition, the intended purposes, wheel material and bicycle style of these wheels vary significantly. Most bike frames fit only one size of wheel, or two very similar sizes of wheels.
There are two types of clinchers: The difference is in the material used to make the bead the part that hooks onto the rim. Folding clinchers generally use Kevlar, a durable material that — as the name suggests — allows the tyres to be folded.
Tubulars are what most pro riders use for racing. The other way a tubular tyre differs from a clincher is that it has to be glued or taped using special double-sided tape onto a rim specifically made for tubular tyres.
Tubulars rely on tyre pressure and glue to hold them on the rim. This is probably more a function of the tendency to run tubulars at higher pressures than their construction, however.
tres Your two options are using a CO2 inflator cartridge containing sealant or tearing off the punctured tubular and replacing it with another, which obviously means riding with 28 inch road bike tires spare. Actually repairing a punctured tubular, rather than simply replacing it, means breaking out the sewing kit.
You can — carefully — ride home on a spare tubular stretched over a rim, but you must glue this new tubular in place before your next 28 inch road bike tires. Gluing a tubular is no piece of cake either and a bad job can result in the tirfs rolling off the rim and a painful crash.
By comparing this dimension you can see if the brakes will reach when a different size of rim is fitted to your bike.
Switching from to for example, needs another 4mm of brake reach. Tyres of the same size may come 28 inch road bike tires lots of different markings: Even worse, the same or very similar markings can sometimes be found on completely different sizes of tyre: As far as possible, then, use these columns to convert to ISO dimensions and then have nothing more to do with those old markings!
The first two headings need no explanation. Hires that American and Japanese branded road tyres tend to be smaller than described and often lack any ISO markings. The table below lists most of the sizes of 28 inch road bike tires that are likely to be found in the UK.
Where you see a block of two or more compatible sizes, having the same bead diameter, you can assume that intermediate sizes exist that will also fit the same rim.
For example: Two tyres with the same ISO markings are completely interchangeable, even if one seems to be metric and the other is also marked 28 inch road bike tires inches: Tures for the ISO numbers and you always know exactly where you are.
News:Apr 3, - 28mm. The tyre height is 1 5/8 inches. E.g. which means 28mm tyre width on rims with mm inner ("bead seat") diameter. Most adult road and utility bikes now have "C" wheels with mm rim diameters.
