The overgearing mentioned in the article was quite possibly due to
the fact that this reduced the torque load on the hub, extending
life and allowing use of lower grade steel parts. IMO the gearing
should have been changed as peoples riding habits changed. From the
article lots of things SA should have done but did not.
Our Australian member, Roger Brandon, has a unmounted SA AW hub he
found with about a 26 tooth input sprocket mounted. Source of the
sprocket is unknown but obviously someone wanted a low geared SA
hub. It is pictured in the photos area.
Even today the only gear hub I know of that is listed by the
manufacturer as suitable for mountain bike use is the Rohloff. Per
their manual that was the design goal for the hub.
The 8 speeds from Shimano and SA, as well as the SRAM 9 speed and
NuVinci CVT, just do not have the gear range most mountain bikers
want. Also at least SRAM and NuVinci list minimum input ratios that
limit the low gear to about 26 gear inches with a 26" MTB wheel, not
as low as wanted by many mountain bikers. Staying within Rohloff
input ratio limits it can be geared as low as just under 18" with
the same size MTB wheel.
