Challenge Shaft Mounted Speed Reducers allow several customisations with regards to the output hub diameters.  For example, a size J SMSR has a standard hub of 100mm that can be reduced with bushes to either 95mm or 90mm.  The unit can also be supplied with an alternative hub accommodating 120mm which again can be reduced with bushes to 115mm or 110mm.
