Rohloff splined carrier s sprocket adapter for speedhub

Product Description Special solution for conversion to a splined sprocket system: the Splined Carrier S Adapter by Rohloff Since 2016, Rohloff has equipped all hubs in the current series with a splined sprocket system. Turning or replacing a sprocket is then very easy without a chain whip or cassette puller. Due to the same component basis (screw connection), existing hubs can be retrofitted or converted with this splined system. For special cases where an adjustment of the chainline is not possible (e.g. special chain case, chain running in the rear triangle, collision with the chainstay due to exceptionally narrow installation space), Rohloff offers the Splined Carrier S. This is to be used exclusively for 15t-19 + 21t splined sprockets and is not compatible with 13t and 14t splined sprockets or Gates belt pulleys. A sprocket puller is only necessary for fitting the splined carrier. The splined sprockets themselves can be changed without a sprocket puller. The reversible sprocket is first fitted onto the Splined Carrier and secured with the help of the snap ring. Then screw the complete unit onto the hub driver as usual with a threaded sprocket. Rohloff offers a template to check for collisions between the frame strut and the sprocket. When using the Splined Carrier, the chain tensioner requires the long frame bolt. The use of a closed chain guard (Hebie etc.) must be checked individually for compatibility. Chainline:Using the Splined Carrier S moves the previous chain line (54 mm with threaded sprockets) as follows: 135 / 142 mm frame w/ splined sprocket:15-21 tooth = 55 mm chainline148 mm frame w/ splined sprocket:15-21 tooth = 52 mm chainline170 / 177 / 190 / 197 mm frame w/ splined sprocket:15-21 tooth = 73 mm chainlineManufacturer's Notice:Due to the extended number of teeth, many chainring / sprocket combinations are possible. The permissible or desired transmission ratio can be determined with the Gears-Meters Table. In practice, a gear ratio (chainring: sprocket) of 2.5 - 2.8 has been proven to be suitable for touring/everyday use. However, if you are travelling off-road and in the mountains, you can choose your own individual gear ratio down to a minimum factor of 1.9.
