The da Vinci frame: built without compromise.

Regardless of component package, the daVinci frame is the foundation and heart of your tandem. Every tube has been designed for the exact stiffness, strength, weight and ride characteristic we are seeking, nothing is off the shelf. We had custom dies made for every tube and the results were well worth it. And, every daVinci tandem has the patented Independent Coasting System (ICS).

Hand Built in Denver Colorado:

Aside from the benefits of the Independent Coasting, you will find that da Vinci Designs tandems are the most comfortable, fast, precise, agile, and stable tandems you will experience. Customers tell us their da Vinci rides more like a single than any other tandem they have ridden. We attribute the ride quality to the race proven geometry, large diameter tubing, careful placement, laser straight alignment and flawless construction.

Tandem Frame Materials

Chrome Moly Steel: Built for strength and durability. Steel gives the riders a lifetime of enjoyment. For long distances, this frame has enough flex to be a comfortable ride day after day. Available S&S couplers.

7005 Aluminum: Lighter in weight, accelerate more quickly, resistant to rust and can climb that next hill with less effort. Aluminum can be comfortable. We have engineered the aluminum frame to equal the steel frame in stiffness for a good ride. This is an inexpensive way to save some weight. Couplers not available on aluminum.

Titanium: Realize a light weight frame with the stiffness needed to accelerate quickly and handle turns with precision. Titanium makes the lightest S&S coupled frame. Build the ultimate travel tandem. Plus it is a beautiful metal. Titanium is slightly less stiff and more compliant than steel and aluminum. Available with titanium S&S couplers.

Carbon Fiber: Lightest weight frames (without S&S couplers) and well known for it’s vibration damping qualities. Carbon fiber does take longer to build and every frame is built to order. Plan ahead, it is worth it. Available with S&S couplers.
