The Concept2 RowErg is available with either standard or tall legs. The standard legs give a 14 inch (36 cm) seat height while the taller legs make the seat 20 inches (51 cm) from the floor. The RowErg with standard legs is the new name for the Model D Indoor Rower. The tall leg option replaces the Model E, which is now discontinued. A higher seat is not required for taller users, and both machines will fit inseams up to 38 inches (96.5 cm). Rowers with an inseam longer than this may require an extra-long monorail.
