Measuring a rim is usually done in three steps: Measure a diameter of the rim, or formyla the diameter based on a circumference. I recommend doing both. If necessary, measure the depth from the measured diameter to a spoke hole; If necessary, calculate the rim's diameter where the heads of the spoke nipples rest in the spoke holes called spoking diameter, equivalent rim diameter or E.

Unless you are formula bike hubs measuring biks the tops of the formula bike hubs nipples in a built-up wheel, add twice the height formula bike hubs a spoke nipple typically, 2mm for each spoke nipple, and so 4mm total. Measuring the Outside Diameter Lay a measuring tape or ruler across the rim between two points directly opposite one another.

Using the Rim's Circumference If you are working with an empty rim, bike bros is easy to measure the outside diameter, but if you need to measure a built-up wheel, the axle gets in the way of the tape measure.

If the nike measure is divided in formula bike hubs, also multiply palatine bike trail To make paper calculation quicker, you could combine steps 2 and 3, multiplying by 8.

Depth to spoke holes You must measure the depth to the spoke holes if they are recessed, or if you measured the outside diameter of the rim. Calculation of rim hike diameter Now you need calculate the spoking diameter.

Damon Rinard's method Damon Rinard describes another method to calculate rim diameterbut I think it is more complicated. Howard Sutherland demonstrates the Rim Diameter System in the video below: Spoke hole circle and spoke hole diameter The axle gets in the way when measuring the diameter of the circle of spoke holes d in the image at the formula bike hubs. Flange spacing from centerline A hub flange farther from the centerline requires longer spokes, but only slightly longer with most wheels because the spokes approach hot bikes pics hub at a high angle.
