A device for measuring five parameters which define the riding position of a bicycle, which device may also be used as a jig to guide adjustment. The five parameters measured are: position height, saddle setback, saddle angle, reach to the bars, and bar angle The device treats these parameters as functions of a given rider's anatomy, and compensating adjustments factor out changes in crank length, height of shoe sole or height of pedal which would otherwise alter a rider's "reach" to the pedals. The device includes the scales and gauges needed to perform all measurements or to be used as a jig, as well as the fittings needed to attach it to a bicycle. No other tools are needed, and no disassembly of the bicycle, including crank bolts or cranks, is needed.

1. A measuring device and adjustment guide for various positional parameters of a bicycle, said device comprising a support section to which a measuring section is attached, said support section includinga main stick which provides a vertical reference in relation to which all said positional parameters are measured, vertical gradations against which vertical relationships to said vertical reference are gauged, a main slot extending through said main stick and serving as a vertical alignment means for vertically aligning the main stick, an attachment hole near a lower end of said main stick, said attachment hole being in vertical alignment with said main slot, a crank adapter which cooperates with said attachment hole and is aligned with said vertical reference, wherein said crank adapter is vertically aligned with the center of a bottom bracket of a bicycle, a first attachment means situated near said crank adaptor and said attachment hole which cooperates with various elements of the bicycle for removably yet stably attaching a portion of said main stick to the bicycle, a second attachment means for removably and slidably attaching a second portion of said main stick to the top tube of the bicycle, and; a third attachment means for attaching said measuring section to said main stick at a point higher than said second attachment means; wherein said third attachment means slides easily along the length of said vertical alignment means yet remaining longitudinally aligned with it, wherein said third attachment means aligns said measuring section with said vertical reference by first being passed through said vertical alignment means from the front of said main stick and then engaging holes on components of said measuring section; wherein said third attachment means also provides a means of altering by degree from slidable to fixed the condition of attachment between said support section and said measuring section, and wherein said measuring section includes an angular measurement component possessing two guide pieces mounted upon one of the faces of the main stick, which face is oriented so as to bring said guide pieces into contact with said vertical alignment means, such that said angular measurement component slides along the length of said main stick yet remain longitudinally and angularly aligned with it, and; wherein said angular measurement component incorporates a means of comparing and quantifying its angular relation to that of a mounting post whose primary axis extends perpendicularly rearward with respect to said vertical reference; said mounting post slidably accepting a longitudinal measuring component oriented such that its angular relation to said mounting post is the same as said measuring post's angular relation to said vertical alignment means, and; wherein said longitudinal measuring component is perpendicular to the primary axis of said mounting post and is at all times parallel to the longitudinal axis of the bicycle, and whose distance from the vertical reference of the main stick may be varied by sliding said longitudinal measuring component along the length of said mounting post; said longitudinal measuring component having a longitudinal gauge attached, the linear distance of said longitudinal gauge from the intersection of said longitudinal measuring component with said vertical reference being quantified by means of scales marked upon said longitudinal measuring component.
