Gates Carbon Drive with Rohloff SPEEDHUB 500/14
The Gates Carbon Drive system replaces the usual bicycle chain with a carbon fiber toothed belt. These carbon fibers help increase the tensile strength of this belt and prevent stretching.
This in turn provides a high working efficiency which together with the belts other qualities, proves that the system is generally suitable for the bicycle transmission.
The main benefit of the belt drive is simply that this transmission does not require any sort of lubrication. Therefore the average life expectancy of the belt drive lies approximately at the same level (if not slighty higher) than that of a high quality chain transmission.
In order to mount the Gates Carbon Drive safely onto a bicycle however, there are several important rules which must be followed exactly just as with any other carbon fiber bicycle components.
Due to the fact that the carbon fibres of the belt can be damaged through imcorrect bending, twisting or through the belt ratcheting over the belt pulley, it is important when fitting, tensioning and when removing/refitting the wheel to pay special attention to the detailed instructions supplied with the Gates Carbon Drive System.
If the carbon fibers within the belt are damaged (which cannot always be externally observed) then the belt will inevitably break. This can lead to accident/injury or possibly death.
Because the belt drive can only be fitted to specially constructed frames, the belt drive is currently not a retrofit component for retailers or cyclists, it may only be fitted by OEM manufacturers.
Further information for manufacturers:
Rohloff are offering an adapter, which is fitted directly to the driver of the SPEEDHUB 500/14. The belt pulley will then simply be screwed onto this adapter.
All manufacturers who wish to offer the Gates Carbon Drive in conjunction with the Rohloff SPEEDHUB 500/14 can source the front belt pulleys and belts from:
Universal Transmissions GmbH, Külftalstr. 18, 31093 Lübbrechtsen,
Tel: 049 5185-60266-50, Fax: +049 5185-957192.
The rear belt pulleys can be acquired from Rohloff directly.
Rohloff will mount the adapter and the rear belt pulley on hubs ordered from us. This simply makes sense as the pulley requires special tools to secure this onto the SPEEDHUB. Because this must be orderly fitted, Rohloff will take responsibility for this task.
The Rohloff warranty is therefore only extended up to this adapter and for the correct mounting of the rear belt pulley. The mounting of the belt pulley is only undertaken in contract for the manufacturers but does not however, include any product quality control.
The company Rohloff AG does not accept any liability or warranty for the Gates Carbon
Drive or for the individual components unless they were exclusively fitted by Rohloff at the
All Rohloff hubs mounted with belt pulleys by us will be registered under their serial
number. All SPEEDHUB 500/14s which were not originally fitted with the adapter by the
Rohloff AG will automatically be excluded from warranty. Furthermore, any Gates Carbon Drive used in conjunction with a Rohloff SPEEDHUB must also be fitted with a Snubber, which is correctly fitted so that the belt is hindered from skipping over the rear belt pulley.
The company Rohloff AG insists that a frame sticker is also present informing the
customer of the important issues that need to be addressed when utilising a Gates Carbon Drive transmission.
There will be seminars offered in the future in conjunction with the company Universal
Transmission GmbH for all interested bicycle retailers as well as all OEM manufacturers who wish to offer the option of a Carbon Drive transmission. The company Rohloff will only offer original spare parts only to retailers who have taken part in such a seminar.
