On the Torpedo Pentasport (5 gear) bikes, there
are often two small loop holes (?) on the chain
stays to direct the wires.
They remind of the same things on a casting rod
directing the line.
Those are most often not on the Torpedo 3
bikes, and I suspect this is because the wire
there are on the opposite side of the chain
guard, so there is no reason to keep the wire
aligned to the chain stay (away from the chain
guard). Once there, on the Pentasport, they
might have thought "we might as well put
another one on the other side as well".
Another reason might be the control or hub
mechanism, which require more power (?) so it
is more important to better align the wire to
the twin pulley wheels by the crank.
A third reason (tho seeming more unlikely) is
to align the gear chains certain ways coming
out of the hub.
What do you think?
Another detail are the rubber "hats" on the
hollow dome nuts to protect the chains
I suppose when you put the bike in a rack etc.
Anyone has a name for those?
