Product Information

In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction of 3 Some rims are also now marked according to ISO with their bead diameter and internal section (width where the tyre fits); 622-17 for the size usually fitted to touring and hybrid bikes, for instance. But some manufacturers give the overall width instead. Subtract 6mm from overall width to estimate the rim section, or simply measure the distance between the flanges. When you've multiplied the ones digit by every digit in the top number, move to the tens digit in the bottom number. Use long addition to add your number columns from right to left, carrying as you normally do for long addition. Long multiplication with decimals using the standard algorithm has a few simple additional rules to follow.

Used on mountain bikes, these tires also go by the names: 27.5+, 650+, 6Fattie, or even just "Plus tires". ISO / ETRTO (mm) the numerator is 3, and the denominator is 8. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5 There is no industry-wide convention for tubeless tyre fitment and satisfactory results are mostly likely using parts made for use together such as Mavic’s UTS (Universal Tubeless System) tyres and rims. Nevertheless, tubeless-compatible tyres are generally available in the standard 29"/700C/622mmISO, 27.5"/650B/585mmISO and 26"/559mmISO formats. It is inadvisable to use non-tubeless tyres without an inner tube as there is a risk of tyre blow-off. Tubular tyresTwo tyres with the same ISO markings are completely interchangeable, even if one seems to be metric and the other is also marked in inches. For example, 650B and 26×1½ are both 38-584 and should be marked accordingly. Look for the ISO numbers and you always know exactly where you are. That’s how the diameter and circumference (circ – equals distance rolled in one turn of the wheel) are calculated in the Tyre size table. These figures are useful for setting your cycle-computer and precisely calculating gears. This process can be used for any number of fractions. Just multiply the numerators and denominators of each fraction in the problem by the product of the denominators of all the other fractions (not including its own respective denominator) in the problem. EX: In the beginning, there have been various measuring systems, with every country that manufactured bikes developing its own method of marking. The same size bike tire could be found with different numbers in different countries. As cycling has become more global, a standardized approach was needed.

Tire solutions for sport, touring and everyday life. Schwalbe is working to eradicate the puncture. While traditional sizing systems are based on the outside diameter of an inflated tire (measured in inches or millimeters), the ISO standard notation uses the diameter of the wheel bead seat in millimeters preceded by the inflated tire width in millimeters. A tire can also have one, two, or even three sets of sizing numbers. As long as one of these sets of numbers on a new tire matches the markings on your old one, the new tire should fit on your rim. The ideal relationship between tyre and rim section is about 1.8 to 1, but any tyre from 1.4 to 2.2 times should fit – always provided that the bead diameters correspond. The initial two-digit number is the tyre section and roughly indicates the tyre width. Its actual width is normally less, but varies according to how the tyre is designed and the width of rim to which it is fitted. But the height of the tyre usually corresponds quite closely to tyre section, so overall diameter approximately equals the bead diameter plus twice the section.Whether you have a city bike, touring bike, road bike, gravel bike or MTB: The tires affect the riding experience like no other bike component. The choice of tire not only determines how well the wheel grips the ground but also influences how easily and comfortably the bike rolls. Ideally, the tire combines such characteristics as maximum grip, high mileage, optimum rolling properties, low weight and reliable resistance to punctures. Sounds technical? The sum of these properties is tangible to every cyclist: as an optimum riding experience. At Schwalbe, we work to continually refine and improve this riding sensation – day in, day out. As far as possible, then, use these columns to convert to ISO dimensions and then have nothing more to do with those old markings! A polynomial with rational coefficients can sometimes be written as a product of lower-degree polynomials that also have rational coefficients. In such cases, the polynomial is said to "factor over the rationals." Factoring is a useful way to find rational roots (which correspond to linear factors) and simple roots involving square roots of integers (which correspond to quadratic factors).
