Stem angles sloping upward are recorded as positive numbers, while stem angles sloping downward should be recorded as negative numbers. It is possible to measure the manufacturers angle by taking the stem angle and the quill (steering column) angle. If this angle is known, record this as well.

NOTE: Some stem manufacturers specify stem angle using the steering column as a reference. It stem is upward sloping, record as a positive number ( + ). In the stem is downward sloping, record as a negative number ( - ). Especially on shorter stems, hold angle finder so it is parallel to stem angle. Measure center of the stem binder bolt to the center of the bars. It is easiest to tape line to saddle so it hangs from saddle end and extends freely toward the ground. Record downward sloping saddles with a negative number (-).ĭrop a plum bob line from the saddle tip and measure distance from line to center of bottom bracket. If the front end of the saddle is raised, record this upward sloping saddles as a positive number (+). Using a straight edge on top of saddle, measure saddle angle from horizontal. Measure from saddle tip to the center of the bars at the stem. However, this number is also related to stem length, fork rake and wheel base, making it less useful when setting up a duplicate position on a different frame. This is a useful measurement when tracking changes in position on the same bike. Measure from lower edge of straight edge to top of handlebars.Īnother option is to measure from the front axle to the top of the bars. Use level finder to hold straight edge horizontal from saddle. Use a straight edge on top of the bars, and measure to lower edge of the straight edge.Īnother option is to use a long straight edge and the level finder. A simple method is to measure perpendicularly from saddle to ground, and then bar to ground, and take the difference between these two measurements. Record handlebar-over-saddle height difference. A simple method is to place a straight edge on top of the saddle and record height from the bottom bracket center to the lower edge of straight edge. Record saddle height and note method of measurement. It is also recommended that the traveling rider carry a recent photo of the bicycle. Assume this will be used in a police report of a stolen bike. Also record bike’s color scheme and any unique or obvious physical characteristics that might distinguish this bike.

Also record bike make, model, year of production, and serial number. Complete the chart and makes notes with the assumption that someone else will need to set up a bike from only this chart.īegin by recording customer/rider information, such as name, address, etc. For example, record “50cm” for fifty centimeters, and “50mm” for fifty millimeters. It is important that the user be consistent and that the method of measuring is noted. There is often more than one method for measuring a component or position. If possible mount bike on trainer and level bike by checking that both wheel axles are the same distance from the ground.
