2 Rohloff Hubs: One shifts harder than other?

Putting a hex wrench directly on the shifter of each, the older one shifts
considerably harder than the newer one and makes a different noise.

It's hard enough so that when the grips are wet, it's almost impossible to
shift.

Anybody heard of such a thing?

The immediate explanation that comes to mind is Rohloff's recent
change to a softer detent spring. I've got three Speedhubs in the
house, and the newest one has the softer springs installed. There is
a notable difference between new and old, both when using an 8mm box
wrench on the external shifter and when operating the twist shifter.

I'm not sure if I like the feel of the new springs. The shifter
almost has a "mushy" feel to it, and the detents have lost a bit of
their definition. I'm probably just resisting change, though — I'm
used to the sharper detents on my other two hubs, and the "soft"
springs are in the hub on my wife's bike (and she's really pleased
with the feel).

Pete, I meant to ask, how do you prep you cables?

From day one I had nothing but bad luck with the Rohloff-provided
housing. I found the removable liner to be too delicate; it crimped
causing excess drag that was readily felt at the shifter.

I've since switched to standard brake cable housing and 1.2mm
derailleur cables, along with a healthy dose of silicone spray
lubricant applied to each housing. This has given me much better
results.

Another help I found was to pack up the external shifter box with
grease ? in my case, lightweight TriFlo synthetic, but I'm sure any
light grease would do the trick. This not only gives the cable pulley
a continuous supply of lubricant against the back of the shifter box,
but keeps a lot of the grit and grime at bay, away from the cables.
This, too, resulted in a noticable improvement in shifting action.

On the same theme, I forgot to mention in my earlier post that Nokon,
the manufacturer of high-priced low-friction cables, offers a set for
the Rohloff Speedhub:

RE/

I've been through so many sets of cables (fooling around with different
installations...) that I've lost track of what I'm using.

I'd give it 97% that they're off-the-shelf Performance bike shop housings with
Rohloff cable inside, thought.

Re/Ed's observation, I thought cable routing was the root of it for awhile
because the "hard" hub was on my hardtail - which has a more tortureous routing
by far. I discovered the "real" diff when I swapped wheels recently to
re-tension the spokes on my FS. So, in this case, cable routing is not a
factor...as confirmed by the 8mm wrench test...

The detent spring explaination seems to fit the best. The new one has started
leaking just like the old one did and maybe when I ask Thomas for the little
axle plate gasket that fixes the leak I'll ask him about a replacement detent
spring as well....I really like the easier shifting, especially when my hands
are wet.
