Gates Carbon Drive belts are made with stretch-free carbon fiber tensile cords. The advanced urethane technology thus allows the belt to be weather resistant, flexible, and durable. Although Gates engineers have developed high performance belt drives for thousands of industrial applications, Gates developed an entirely new belt to specifically meet the performance requirements for the bicycle industry.
- Carbon fiber is the base technology, giving the highest modulus and strength
- Urethane body is rust-proof, even after 192 hours of salt-spray test
- Unlike chain, carbon fiber is length-stable and will not stretch
- 11 mm pitch profile is designed for optimal belt drive performance to meet the demands of human power
- Paired with the Gates patented sprockets, the system provides smooth and quiet meshing, and proven durability
**Proper installation is key, view the Owner’s Manual for more information.

THREE KEYS WHEN WORKING WITH CARBON DRIVE
Gates Carbon Drive belts are highly durable and offer long life when properly handled. However, you must use caution 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 118 Tooth CDX Belt Black, 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, you need proper belt tension 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.
