Freewheel replacement for UltraRear SX/SLX/SPX Version 1 & 2.
Spare Freewheel can be installed only as replacement of identical freehubs (these are not conversion kits)
The freewheel includes body, bearings, pawls, O-r spring, O-r seal and its individually matched bushing.
Before ordering check if your hub has the writing "version 2.0", otherwise your hub is a (version 1)
Important tech note
The freewheel installation requires rather high tech skills, quality tools and a well-lighted, clean working environment.
The installation always involves the following operations:
- Perfect cleaning of freewheel internals
- Replacing the old "TX-Bushing" with the new one supplied.
- Dry pre-assembling of hub with the new freewheel + TX-bushing and tuning of axial tolerances
- Freewheel greasing and final assembling
- In some cases it's also necessary to adjust rim camber
Before ordering carefully read and consider the instructions (our website's Tips & Manual section) to decide if you can really do it by yourself.
