If you intend to use a rim washer, install it now to factor it in to your measurement. Select a rim hole and engage a spoke through the hole. Using a spoke ruler, we determine that our measuring spokes are 266 millimeters Spokes are typically available in whole millimeter increments. Note that these are not necessarily the spokes or nipples we will use to build the wheel - any identically-sized spokes will do, they only need to be short enough to not meet in the middle.ĭetermine the length of your measuring spokes with a spoke ruler and record this number. This is accomplished with two J-bend spokes with standard slotted nipples, acting as measuring rods. We'll calculate the distance from the end of this spoke to the same point on the opposite side. This cutaway shows the ideal spoke length, with the spokes threaded fully into the nipple and no further. However if you have the rim in hand, it is worth measuring this yourself.Īs we are looking to measure to a point inside the rim, there is no practical way to measure the ERD directly - it will require a few measurements, and then some simple math. This number is sometimes provided by the rim manufacturer on their website or in the included literature. The common term for this is ERD, for Effective Rim Diameter, although a better term would be Effective Spoke End Diameter. We are concerned with the diameter as defined by where the end of the spoke sits when it is fully threaded into the nipple. There are a few ways to measure the diameter of a rim. Count them and make sure it matches your hub. The first consideration for the rim is simply the number of spoke holes.

We will walk through how to find each of these measurements. Left and right hub flange spacing relative to the hub center.Hub flange diameter at the spoke holes, also known as the Spoke Pitch Diameter.The effective rim diameter, called the “ERD”.The number of spoke holes in the hub and rim.The measurements and information you need to determine spoke length are: In some cases, you may find it best to take your own measurements. In the end we will round to a whole number for our final spoke length.Īlthough there are online databases for rim and hub dimensions, not all third-party databases are current or accurate. This helps prevent measuring errors from compounding along the way. When using a caliper, take measurements to one tenth of a millimeter. These measurements can be fed into online spoke calculators to run the formulas that arrive at a final length.Īs you proceed, try to measure accurately.

Spokes are typically available in 1 millimeter increments, and the proper length is determined by formulas which are based on a series of measurements. Having the spoke up into the nipple reinforces it, and helps prevent cracking and failure of the nipple, especially aluminum nipples. If done correctly, the measurements and calculations done here will result in spokes that are just fully threaded into the nipples. This can be bad news for the tube or tubeless setup. Looking into this rim we see that the thread of the spoke extends far beyond the nipple. In the cutaway, we see that both the spoke and nipple have a lot of unused thread, resulting in poor engagement. This excess thread is a clue that this spoke is too short for this wheel configuration. If this occurs, review your numbers and measurements. This is typically from inaccurate data entered into the spoke calculators, not the spoke length formulas themselves. Straight-pull spokes (top) are not covered in this article.īe aware that when determining spoke length from scratch, it can sometimes occur your results are less than desirable. This procedure applies only to J-bend spokes (bottom). Consult with the rim and hub manufacturers for compatibility issues if you are unsure.įor the purposes of this article, we will assume you are building with common J-bend style spokes. This means considering your axle type, brake type, and frame dimensions among other things. Two spokes and two nipples to act as measuring device (size not important)īefore determining spoke length, you’ll need a rim and hub that are both compatible with each other and the bike in which the wheel will be installed.A worksheet to record your measurements.
