This  720 Crew came to us on trade-in. It has been reconditioned and is ready to rowl. It provides a great, fun, total body workout, but has a 7 speed derailer and caliper pull brakes instead of our NuVinci Hub and Shimano Disc brakes. Since this Rowbike was built by a previous manufacturer, it does not come with our 2 year warranty and we can not guaranty replacement parts will be available.
