Tandem bicycle

Borthwick tandem bicycle. Custom made in the USA Only 169 tandems bicycles made like this. All original and well maintained. I replaced both tires and tune it up before posting this. Steel frame with Aria aluminum wheels. All specialize components. 3 by sprockets in the front It comes with an air pump custom painted to the bike and it attaches to the frame. It has a detachable crank for a child with a red chain, you can see that on the picture. This bikes were made for both wheels to brake with the right lever and the left lever applies a drum brake in the rear ( the black disk in the rear). They work very efficient. I cannot see the frame size but I'm a 5''-10" guy and my stoker is 5'-6", we did a few races on this and it was a very comfortable bike to ride. Gordon Borthwick was a aeronautical engineer that build bicycles paying attention to every detail. Look at the seemless welds. McClintock and Elliot in Tempe.
