da Vinci / Calfee Carbon Tandem
Why did da Vinci Designs change the frame design? The new frame is… 15% lighter. - Accelerate quicker, easier to climb with and easier to load on your car. 39% stiffer at the head tube. More responsive for a better ride and more confidence in the corners and high speed descents. 7% stiffer vertically We did not want to add too much vertical stiffness to keep the ride comfortable. Better water bottle placement Five nearly vertical bottle locations are easier to reach and help keep the sticky drink residue from building up on your frame. Fewer S&S couplers on “Global” models and bigger open spaces between frame tubes. If you have ever packed a S&S bike into one case, you have probably had a tough time keeping the axles away from the lateral tube. It is always right in the middle of the case and in your way. The ride characteristics are impressive to say the least. Why wasn’t this done years ago? This has not been done in the past because until very recently the technology to manufacture the long, multi-butted, larger diameter tubes needed to make this work either did not exist or was not readily available to the bicycle industry. Custom Rear Derailleur
In celebration of our 10th year building tandems (back in 2005), we started offering several of our most popular upgrades for one reduced price. This package was so successful we decided to continue offering it. NEW in 2005
We now have 3D cast head badges.
If you bought your bike
before we had these little gems made, fear not they are easy to install and
available for $15.
All new da Vinci Tandems come with the Anti-Chain-Suck bracket pictured below. This hero works invisibly, preventing the chain from wrapping around the chainrings no matter how hard you are pedaling while you shift, or how dirty or dry your chain is.
We have also created a bolt-on model for all da Vinci owners that have a 2" diameter round keel tube (bottom tube that connects both bottom brackets). $95
