A super high quality clutched singlespeed kit from CNC Meisters SB One. A complete singlespeed solution in one kit. As far as we're concerned, this is the best singlespeed kit available right now and it's the one we chose for the Slacker Park bike. The CNC mud spacer kit and 14t sprocket fit directly to a standard HG freehub body and offer 18mm of 'infinite' chainline alignment. The tensioner itself is a work of art. Where conventional singlespeed tensioners are little more than a spring and a jockey-wheel, the G3C has a built in, manually adjustable clutch system. This allows you to adjust the damping according to your own preference and also to tune it to work optimally with your suspension setup. Key Features Manually adjustable clutch Infinitely adjustable chainline Cagelock for easy wheel removal Compatible with HG freehubs Tensioner, 14t sprocket, lockring and mud spacer kit included Weight: 200g (tensioner) 282g (complete)
