19 Tooth CDX Sprocket Rohloff Spline
Technical specifications for 19 Tooth CDX Sprocket Rohloff Spline:
|MOUNTING STYLE||Rohloff – Splined|
Note: These sprockets should only be mounted on a Rohloff-approved frame. A Rohloff Carrier (ART NO. 8540) is necessary to mount the CDX Rohloff sprockets and may be ordered at Rohloff. A snubber wheel for the Gates-Rohloff combination is also required. For technical information, download the Gates Rohloff Manual.
Gates sprockets provide a slimmer profile, lighter weight and better debris shedding, thus giving maximum drive performance in all environments, including muddy or snowy conditions. The patented CenterTrack design keeps the belt aligned on the sprocket.

THREE KEYS WHEN WORKING WITH CARBON DRIVE
Gates Carbon Drive belts are highly durable and offer long life when properly handled. However, caution must be used before and during installation to avoid damaging the carbon tensile cords. Excessive bending and twisting creates invisible crimps, which can lead to belt breakage.
In handling the belt, you must NOT:
– back bend
– use as a chainwhip
– twist, or
Alignment is critical. Depending on the particular bike and setup, you may therefore need to use spacers to ensure proper alignment. Noise, wear, or belt walk-off can be caused by sprockets that are out of alignment.
Finally, proper belt tension is required for optimum drive operation. For frames with vertical dropouts, changing a flat tire will not mean you need to re-tension your belt. Tensioning is also easy with the Gates Carbon Drive iPhone® app (available for free download in the iTunes® App store) or Carbon Drive Krikit Gauge or the ecotension tester (available in Europe). Unusually low tension can cause the belt to skip, thus leading to decreased performance. But don’t over-tension the belt, because this will cause drag and unnecessary wear.
|TENSIONING RECOMMENDATIONS||SMOOTH & STEADY PEDALING STYLE||PUNCHY & ROUGH PEDALING STYLE|
|MOUNTAIN & SS URBAN||45-60 Hz (35-45 lbs)||60-75 Hz (45-53 lbs)|
|INTERNALLY GEARED HUB||35-50 Hz (28-40 lbs)||35-50 Hz (28-40 lbs)|
These tension recommendations are a good starting point, which you may need to adjust higher or lower as a result of differing rider size, gear ratios, or power placed on the pedals.
