The Extendable Bike Fitting Goniometer makes it easy to assess range of motion, body joint angles, and ultimately provides a more accurate bike fit for cyclists.  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.
