Concept 2 Rower - Seat Roller, Top
For use with Model C, D, E and Dynamic Indoor Rowers. One of the 3-1/4 inch wide top seat rollers (two per machine; sold individually) that runs on the stainless steel track on the monorail. Mounting hardware that holds the roller on the seat frame is not included, because it can usually be re-used. If you need the hardware, order part number 1728 instead. See more info.
