DM ATU and allen adjustment

Is the DM ATU still a decent uni? From what I’ve heard the main upgrade
needed for it is a larger tire, not quite 3" but the one right below that.
And lighter cranks would come next. Anyhow I have been riding it on and
off for the past year and a half or so and I’m improving… my question is
about re-tightening the allen bolts at the base of the frame, two on each
side. Too tight and the wheel has trouble spinning, and too loose or not
quite done correctly and they tend to creak a little when pedalling. Whats
the fool proof way to torque them down properly?

Tri-Flo, then tighten as much as you can without reducing wheel spin.

To add to Chris’ reply to “Someone,” The DM ATU is still great for me! No
problems. I haven’t taken the cranks off, but similar splined cranks seem
to be mostly made of steel, so I don’t know that they are any heavier
than average.

For the allen bolts, follow Chris’ advice, but then check them
periodically during the first ride, and before each subsequent ride. I
have not had a problem with them coming loose.

No matter what happens in life, somebody will find a way to take it
too seriously

I will just add that the important bit to comment on this is “without
reducing wheel spin”. It is incredibly common to find bearings over
tightened. It is very easy to tighten bearings to the point where the
outer casing is deformed. I generally recommend tighten to where it feels
tight then loosen by a quarter turn. It is very rarely that the bolts
will come loose with this technique, but it is always good policy to
check nuts and bolts after a little loose to check that they are still
were you want them.
