What is the wheel factor for a bike with 26" diamter wheel, with width of 1.95"?

Question

They have some common wheel factors listed and the closest to mine is 26" X 1.75" which = 2045.
How are they arriving at 2045?? thanks!

Answer 1

Bicycle computers manufacturers usually have some 'standard' wheel sizes, but they're not that accurate.

Some tires are taller than others, so maybe a 26"x1.75 might be 2045 mm, but another 26x1.75 from another manufacturer (or maybe just another model) might be 2050 or 2040 or something like that.

What I recommend you do is measure the circunference of your tire. To do this you place your bike and place a mark on the ground and your tire. Then you move your bike forward until the tire makes a complete turn, and mark that spot on the ground. Then measure the two marks on the ground.

Do 3 different reading to make sure you have the right number in milimmeters.

Answer 2

Wheel Factor

Answer 3

You will need to do a procedure called a ( Wheel Roll Out Method) and use the valve stem to make your marks on the floor. Inflate tires to riding pressure. Position your bike ( I like to use my kitchen Floor for this procedure) so the valve stem of the front wheel is at the bottom position and mark the floor (pencil works great)
Roll the bike forward in a straight line while applying pressure to the handle bars to simulate rider weight.
When you move the wheel one complete revolution again mark the floor according to the valve stem.
Measure the distance on the floor, at this point and you asked how they came up with the figure 2045 or what ever figure you come up with is done by converting inches to millimeters 1 inch = 25.4mm so your distance in inches x 25.4 millimeters will give you your wheel setting for your computer.

Answer 4

I could start off doing a cart wheel but would end up in a heap on the floor...

Answer 5

its just a code for the computer
