Tandem Frame Sizing

Our tandem bikes will show two numbers in each frame size, the first number relates to the Captain (front) position and the later to the rear (Stoker) position. The size of the frame is measured in inches from the top of the frame at the point where the seat post is inserted, down to the centre of the axle carrying the pedal arms (bottom bracket). We quote the stand over height (distance from the top of the highest tube in front of the saddles to the floor) at the Captain and Stoker position on each frame.
