has anyone had experience touring on this type of hub?
the S3x, Is it ? is fairly recent introduced in what, last 3 years?
range is a bit limited , when you have a load on , walking the hills will be probably in order..
The AW3 is well proven.. 1 planetary with 2 pawl rings to drive thru Reduction and overdrive gears..
changing the driving and driven relationships,, low 3/4, high 4/3..
they have a plain bearing, except on axle and the sprocket driver,
which makes keeping Lubricant in the hub pretty important.
my Brompton has an AW3 in it, and a Schlumpf Mountain drive, to tackle the hills ,
2 speed planetary crankset, low range uses the 3 speeds over again, 6 in a row.
Misters Sturmey and Archer started making their hubs 100 years ago.
every single part of an AW3 is available,
that is something that is a challenge for troubles with Shimano and SRAM hubs, in the US.
the world traveled German precision IG mountain bike hub from Rohloff
I got one built into a Bike Friday, with 406/20" wheels..
