Description
This is an excellent goniometer for the professional bike fitter. As a bike fitting tool the Extendable Goniometer makes it easy to assess range of motion and body joint angles. Its arms can extend to 28 inches to measure large joints and retract to 8 inches to measure all but the smallest joints. Unlike standard goniometers that require the examiner to estimate alignment, the length of the extendable arms allows it to lie over anatomical bony landmarks.
The dual scale of 0-180° and 180-0° is viewed through a magnifier, improving the accuracy of the reading, and reducing the chance for error. The scale is custom hi-lighted in several bands for ease of reference when using angles from the Fit Kit and FIST bike fitting protocols.
Its lightweight ABS plastic construction will ensure continued and long lasting use. The Extendable Goniometer features a Dual Scale, 1° Increments, Extendable and Retractable Arms, Magnified Reading Window, as well as a Compact, Lightweight, and Portable Design.
Replacement arms are available if you snap one off by accidentally putting it through a spinning bike wheel!
