Purpose Built
The Dragonfly Tandem utilizes the same thoroughbred race design it gets from its one-seater sibling. Boron fiber infused tubing and high modulus carbon allow us to create the lightest and stiffest tandem on the market, all without sacrificing the durability and build quality that you have come to expect from a Calfee.
Refined Design
Our unique lugged design creates a stylish and speedy aesthetic, while also acting as the backbone of the tandem. Unmatched suppleness and comfort are defining characteristics of this design in every Calfee we produce, and the Dragonfly Tandem is no exception.
As Light As They Come
Utilizing our unique carbon construction process, we are able to achieve fantastic weight saving without compromising durability or strength. Our large/medium Dragonfly Pro frame weighs just over 6 pounds!
Up To Standard
We design our tandems with all of the modern cycling standards you love such as tube-in-tube internal routing, hydraulic disc brakes, and through-axle spacing. The eccentric bottom bracket and belt drive platform delivers consistency, reliability, and simplicity to top-off this ultimate performance package. See our Technical Specs
Build Kits
Our expert-selected build kits utilize your favorite components from the likes of SRAM, Shimano, Campagnolo, and more to deliver a well rounded package while eliminating the guess work related to tandem construction and specifications. Each unique build kit is thoroughly tested to ensure maximum reliability and performance. See available Build Kits for this model.
