Spinergy Tx2 Tandem Wheelsets


Tx2 wheels use PBO rather then Stainless Steel spokes.  So what does that mean to you, a softer ride.  Although little vibrations that come from our roads get absorbed by the PBO spokes.  So the ride is less put less wear and tier on your body.  Each wheel is custom built to your choice, spoke color, rim size and width, hub size.

Co-Motion Periscope Torpedo


The Co-Motion Periscope Torpedo was developed so that the Owner of Co-Motion Dwan Shepard could ride with is daughter.  But it has become even more popular with woman who don’t like to throw there leg over a high top bar, and with couples that have a wide height difference.  Wendy and I have ridden one for over a month and found it very comfortable.

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
