number of links in Shimano 1S chain

According to the Maraton manual, the chain
should move vertically 10-12 mm which is
difficult to achieve.

Getting the wheel straight isn't easy either
unless there is some method I'm unaware of.


The way we did it when I was a kid was to tie a string to the front of
the front wheel rim and then stretch across the tire and back to the
rear of the rear wheel rim. Turn the front wheel until the string just
touched the side of the front tire on both the forward and rear side
of the tire. Then adjust the rear wheel to match. Think of the
stretched string as just a long straight-edge

We usually adjusted the wheel for chain tension and then aligned the
two wheels. And then check the chain tension again :-)

I've experimenting with different ideas, e.g.
using two ring wrenches to pull at the same
time to minimize the wheel movement from
pulling the nuts.

Also I thought of locking the nuts almost but
not entirely, then use a soft hammer to perfect
alignment, then pull shut.

It seems there is always some barely-but-still
detectable imperfection visible from some point
of view or the other...

Thanks for all pointers. I was excited to try
them out today but for whatever reason this
time there were no problems getting the chain
tense and the wheel align. If anyone manages to
figure it out how it all works he is a smarter
person than me.
