Da Vinci Symbiosis XC




This bike is a BEAST whether you are blasting down a fire road or pushing hard in your favorite race. The Symbiosis has become the benchmark for off road/cross country tandems. With race wins in the 24 Hour of Moab, Leadville 100, and Vail Ultra 100 you can see that the suspension does its job, and delivers a great ride in the roughest trail. With the drop top tube you get a much better standover and suspension adjustment. It is now available in both 27.5 or 29 wheels. My wife and I had a 27.5 plus size and enjoy riding the fire roads trails of northern Michigan
