Creaking Marin Frame

Ian G Batten said:

My Marin Mount Vision, a few months old, has acquired a creaking noise.
It's said to be common with them, but it's bloody annoying. It seems to
be vaguely correlated with pedaling, and I'm fairly certain it's not
correlated with suspension movement. The dealer wants to look at it,
and they're muttering that the bottom bracket might need greasing. Does
that sound plausible?

Yep.

I had a bike (Marin, but I don't think that matters here) that ended
up going through lots of water over the bottom bracket. Within a week
I was getting an annoying creak when pedalling. Pulling the bottom
bracket and covering everything with grease took care of the problem.

Let them try it.

Yes.

PS: you can troubleshoot this yourself by moving/compressing things and
standing up/sitting down, attempting to isolate the sound and rule out
various causes. Tri-flow is your friend in the end.

Could be the crank(s) not fully tightened onto the bottom bracket, easy
to check.

I had that on a new bike. Painted steel shell and plastic threaded BB.
Grease on the thread cured it instantly.

Yes. My oldish Rift Zone has creaked on occasion and my mates Mount Vision
is having a field day at the moment.
Causes in my case were bottom bracket, usually cured by wrapping PTFE tape
around the threads before fitting and crank/bb interface eventually cured
with new cranks (still using tapered bb).
It still has creaks at the mo of which some are coming from the saddle and
some from gawd-knows-where.
Mates MV creak we think is coming from the swing-arm shock mount. Why this
is so we don't yet know but he recently fitted a Whyte bearing conversion
and there may be something amiss with the installation.

yes. My Marin Bear Valley has squeaked twice, once cured by tightening
the crank arms, once by greasing the BB.

Very difficult to track down and sometimes even though you can trace the
approximate source the exact cause is invisible.

If you get a creak with one side of pedal and not the other that's a
clue. And may I suggest that you try lopsided peddling anyway because
that might result in exaggerated body movements which you can then
switch by lop-other-siding.

Experiment with power strokes while just touching handlebars with finger
tips. That should eliminate headset.

1 x cadence looks like BB/pedal
2 x cadence looks like something else

Does it creak when you drop off a pavement curb? I don't know the style
of bike but suspension and saddle/seat post are pretty creaky.

There is no such thing as a completely silent bike.

My Marin BB started coming undone after 1000 miles so check the funny
inside-out nuts that keep the BB cartridge in place.

Yes. But saddles also develop creaks, as do seat posts, as can cranks.
None of these things are serious. The handlebars on my Cannondale creak
rather alarmingly, but there dosn't seem to be anything wrong with
them.

It turned out to be noise from the top mount of the rear shock.
Obviously is _was_ related to suspension movement...
