Clutch designs and materials used have changed over the years as technology and manufacturing processes have evolved. The first clutches (WaterRower series 1 & 2) were all metal, about 3″ in diameter, and comprised of a bolt-on or bolt-on and velcro, handle strap attachment.
M1 models had the addition of the bolt/velcro from 2010, 2011 and 2012. M1 and S1 models changed over to the bolt on/plastic clutch in December 2012 through January 2013.
Up until approximately the beginning of 2013, on series 3 and series 4 all-wood models, machines had metal clutches and handles were attached with velcro only .
The new style Plastic Housing clutch was developed for A1/Indo-Row machines and was carried over to all S4 models (including all-wood) in 2013. It is identified most easily by the black plastic flange (or lip) on the top and bottom. It tends to retract faster than the metal clutch and this is a key feature for the upgrade.
The Indo-Row Studio had the bolt-on/velcro attachment in 2010 and 2011, transitioning to the newer plastic housing clutch with bolt-on handle in approximately July of 2011.
