Has anyone had ticking or creaking issues with their Hollowtech II cranks? On the image, I am suspecting the areas with red dots which is where the crank is pressed into the spider.

Thanks.

My LX 580 started making a very quiet ticking noise after I pulled the thing apart last week to clean and re-grease the bearings. Not too annoying, so I'll live with it till the end of the racing season then likely give the bike another full servicing.

Mine was the opposite... taking it apart and simply wiping everything down and reinstalling solved a ticking noise for me. I did not go so far as to try and repack the bearings or anything like that, but I did take the bearings/cartridges out of the bottom bracket to get everything good and clean, then I wiped a thin layer of Rock and Roll grease onto the axle. I think that fine bits of grit get in there between the plastic parts.

You should also check the chainring bolts.

My xt 760 crank was ticking at the 2 o'clock position. Tore the bike apart. Checked my cleats, tightened bb (not gorilla tight). Everything...except my right pedal was a wee bit loose. Put some grease on, tightened, no tick.

mine ticks sometimes, seems like it goes away after a nice bike washing or some creek crossings though.
That's pretty much what mine does, but it always gets worse in warmer, dry weather and when I leave my bike in my truck when it's hot outside.

question

not to contradict you, but why are you suspecting thoose pressed in areas are the culprits? There are a dozen other places where I can think the tick might come, have you checked them already?
Besides, I really find odd a pressed inn such junction can make any noise. A tick means movement, which I doubt...anyway, just guessing

I've checked all of the typical areas:
- Changed chain
- Inspected cassette
- Tried different wheel set, cassette
- Removed and lubed BB
- Removed and lubed chain ring bolts
- Removed and lubed pedals
- Lubed seat post
- Lubed rear skewer
- Lubed derailleur

Why do I suspect those pressed in areas? Because last year, I squirted a lot of oil around the seams where the red dots are and it went away over a few days. Could be coincidental but I don't know.

It could be a pedal bearing but I am having difficulty detecting exactly where it's coming from. I hear a slight tick in the right pedal at the twelve o'clock position only when I pedal backwards. But this sound is nothing like the ticking that occurs when climbing.

i see

well, if you dripped oil there and tick went away, it looks like that really is it ...for strange it sounds.
Well, we had a costumer installed a new 760 crankset and he had the chain jumping when cranking hard. We replaced pawls in freehub, chain, cogs, wheelset, derailleur...nothing, still jumping.
The culprit was a missmanufactured middle chainring. Shimano makes mistakes too

Same problem here.

I have noticed the same problem recently. Mine also ticks once per revolution.

Here is the odd thing. If I remove the chain from the chain ring and spin the crank,
nothing.

If I sit on the bike and pedal (still with the chain off the chain ring),
the cranks click at about the 2 o'clock position. I can feel the click
in my feet (in sandals, not clipped in.) Pedaling forward or backwards.

It also seems when the setup is cold, it does not, but will start after a bit of
riding or spinning. If I set the bike aside, the click takes a while to come
back.

Have done the usual, tighten and cleaned the bottom brackets, lubed this and
that, made sure the crank screws are tight to spec. I thought the
free crank was making the noise at one point.

I believe the problem is I have dinged the bearing races/bearing from
flying and landing off small jumps. I get a very distinct click, but when
riding with the chain on it is more muted. It seems that the click corresponds
to where my cranks are positioned when I land.

What is frustrating is on the bike stand I can't get it to do it, so hard
to say exactly where the noise is coming from. And it seems to get
louder as the ride progresses (and might depend on air temp.)

I was going to post and ask if it was easy to destroy shimano XT
external BB bearing set by jumping the bike. I guess the answer is
to spend some $$ and see if I can buy just the bearing set and not
the entire kit.

I tried injecting various lubricants into the crank arm (crank arm/chain ring arm area
on the Hollowtech.) No change in my case.

Last month my DeusX was clicking at the 2 o'clock position under power, put the crankset into a new frame and no clicking so far.

this one makes me think of a non properly faced bb shell as a possible reason

Nah, was in a 5 year old frame. This warranty replacement DeusX was on the bike for 9 months before it started clicking, the previous DeusX was in use for a year with no clicking but wobbled on the splines.

I took it out of the old frame, cleaned it up, installed in new frame, and viola no more clicking. Old frame was an '01 Ellsworth Truth, crack inspection was part of the routine everytime i lubed the chain, no cracks.

Source of Ticking Sound Found

After removing the BB and re-taping and greasing everything around the cranks again I still had the ticking. Everything else is now very smooth and quiet,

But I believe I've found the problem. It's one or both of the pedals. I put on some old pedals and the ticking is gone. Now the question is, what in my Shimano 959 pedal is ticking. The bearings seem smooth and nothing is loose.

So remember to check your pedals if you have drive train noise particularly a ticking sound.

Utter and complete humilation. After days of testing and playing, finally went
over the the LBS to consider a new left bearing. Loose pedals! I'm a idiot :eekster:
I checked everything, everything (even hand checked the pedals I thought, but
did not take a wrench to them.) I have the same type pedal, bikeshop guy
said something about his same type pedal also clicks. So far looks like the pedal
tighten has cleared my issue (cross fingers.) But since the LBS did the actual
wrenching instead of me, they might have just exorcised the tick poltergist :thumbsup:

Bought a dedicated pedal wrench. :cool:

I have the creak issue...it is always under load..

I have checked and lubed the following:
Pedals
Suspension pivots,( note I can bounce on it with no weight on crank and it wont creak)
checked all cable routing,
lubed the seat post and rails..
Took the crank off, checked the EX BB by moving them all seems smooth, greased the crank spindle and the interface, and the O-rings.
Checked all bolts on chain rings. all within spec..

( did looked closely at spindle driveside and found what appears degradation of the spindle, :skep: seems that the chrome or shiny material has gotten hot, and is starting to flake away...Very close to the spindle and drive side crank arm...( where the EX bb bearing would be in contact) Is this normal...:skep: )

If I pedal up hill very noticeable, and if on flats or etc.. and very light on the pedals, like spinning quickly it is not as noticeable...Have had these cranks for less than a year...Will post pics later...What do all ya think....:madman:

I think was exactly my problem. I cleaned and re-greased the pedal threads with some really good grease, tightened the pedals pack on and the ticking is gone.
