Strap Wrench CDS
Strap wrench CDS for removal of rear sprockets. Designed for quick, easy removal of your rear sprocket, the Gates Strap Wrench CDS is similar to a chain whip and holds the cog securely in place for easy removal of the cassette lockring. Equipped with a reinforced strap and an anodized alloy handle, this wrench is strong and easy to grip and is a must-have for any bike mechanic or bike shop owner. To prevent damage, never use a Carbon Drive belt as a chain whip. The Strap Wrench CDS is an improved tool as compared to Strap Wrench SPRKT-8, and Bike Knack recommends purchase of this item.
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
HANDLING
Gates Carbon Drive belts are highly durable. They offer long life when properly handled. However, caution must be used during installation to avoid damaging the carbon tensile cords. When they experience excessive bending and twisting, this creates crimps, which can lead to belt breakage.
Because of the risk of damage, in handling the belt, you must NOT:
– back bend
– use as a chainwhip
– bundle
– crimp
– twist, or
– invert
ALIGNMENT
Alignment is critical. Hence, depending on the bike and setup, you may need to use spacers to ensure proper alignment. Noise, wear, or belt walk-off can be caused by sprockets that are out of alignment.
TENSIONING
Proper belt tension is needed for optimum operation of the Gates Carbon Drive system. However, for frames with vertical dropouts, changing a flat tire does not mean you need to retension your belt. Tensioning is easy with the Gates Carbon Drive iPhone app (available through iTunes). You can also use the Carbon Drive Krikit Gauge or ecotension tester (available in Europe). Low tension can cause the belt to skip, leading to decreased performance, while high tension can cause drag and unnecessary wear.
TENSIONING RECOMMENDATIONS | ||
SMOOTH/STEADY PEDALING STYLE | PUNCHY/ROUGH PEDALING STYLE | |
MOUNTAIN OR 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 provide a good starting point. However, you may need to adjust the value higher or lower to reflect rider size, gear ratios, or power placed on the pedals.
