Road bike standard wheel size. Bikecalc takes this view. You can find them with 26 wheels 27 5 wheels or 29 wheels. This wheel size is the largest available for conventional bicycles giving a racing bike more stability at high speeds. Mountains bikes now come in three different wheel sizes.

Bike frames are measured from the middle of their bottom bracket to the end of their seat tube. If all three have a 15 frame there will be a height difference between them due to their wheel size.

Generally bike tire sizes are indicated with two numbers that correspond roughly to the outside diameter of the tire and the width of the tire. Also expect to find rims ready for tubeless gravel tyres. The size of a bicycle wheel is usually measured using the tire size which comes in several stock sizes that are universal across the world. Racing bikes use the 700c size which has a tire bead set diameter of 622 millimeters.

For example a standard road tire is 700c x 23mm indicating a tire diameter of approximately 700mm and a width of 23mm. Since the tire wraps around your rim the wheel diameter includes the tire on both sides thus the multiplication by 2. So the rim spec will be 622 x then another number this other number will refer to the rim s internal width for a road bike this could be a number from 13mm up to 25mm with most road bike rims in the 18 19 mm area. And 29 inch wheels are the same size as 700c.
