|ticking crank / bb||took|
Sep 15, 2003 3:10 PM
|I'm getting a ticking sound from the BB area when i stand up on the pedals. I took off the cranks and bb, re-greased the threads on the bb, then re-installed and tightened. Also greased the bb spindle and re-installed the cranks nice and tight. I checked the chainring bolts to make sure they were tight too. STILL, it ticks when out of the saddle. Any suggestions? I am using a DA 9 spd crank w/ an ultegra BB. And, my frame is titanium.|

|This may sound odd, but if you have eliminated everything in BB area and all is torque'd to spec - try removing the rear cassette and giving it a throrough cleaning - clean the chain as well. THe same thing happened to my and after a cleaning the sound went away....

|From experience (mostly bad) many sounds that seem like they come from the BB do not. Not sure if what you describe is a sound or can you feel movement? Some other stuff to check:
shoe cleats and cleat bolts
inspect frame for cracks
You could also try removing the BB, and wrapping 1 or 2 turns of Teflon tape around the threads. These things can drive you insane. Good luck

|It is fairly common to have clicking noises, but ticks and clicks are very hard to eliminate sometimes. What seems like it is tied to the pedals may be coming from the seat post, etc. Sometimes things like temperature and humidity can affect noises as well. To eliminate chain ring bolts as the problem, take them all out and grease the threads, the faces where they contact the CRs, and the CRs where they contact the crank spider arms. Clicks tied to your pedaling can come from the BB (grease all threads in contact with the frame and BB, and torque it to the recommended settings, which can be quite high), the pedals (grease the threads, get some wax etc. on the cleats, grease the bolts into your shoes, squirt some lube into the guts of the pedal machinery if possible), the chain (clean and lube), your seat post and saddle (grease the post, seat post bolts, saddle rails), your bars and stem (grease the stem, stem bolt at both ends, h'bar bolt, and h'bar where it goes through the stem), and your wheels (check for spoke tension, particularly on the rear non drive side, put a drop of lube where each pair of spokes cross, grease/tighten QRs, tighten cassette lock ring). Needless to say, you want to try these things in what seems like the most likely place the noise is coming from, but there are plenty of stories about "I was sure the noise was in the handlebars but it went away when I tightened up the spokes in the rear wheel," so keep trying different things until you have success.|

|the seat post clamp. I tried many fixes for a BB(I thought) tick. After many tries the one that worked was removal and greasing the seat-tube clamp. Of course this only applies if yours is removable. Also a possibility is the seat clamp itself.
Good luck, this tick is amazingly annoying.

|Boy, do I feel your pain! I'm going through exactly the same process now and am beginning to get EXTREMELY frustrated. Last night I pulled my cranks and bottom bracket, cleaned everything thoroughly, greased everything that has a thread (chainring bolts, BB cups, etc.) and made sure everything was torqued to spec when I re-assembled. Absolutely no change whatsoever.
I realize that the conventional wisdom is to check out other areas like the seat tube/post interface, seat rails, pedals, shoes, headset, etc. - which I'll undoubtedly do. However, I don't hold out much hope for any of these for the following reasons:
1. I've swapped out pedals/shoes with my MTB and it made no difference, so I'm thinking it's not a pedal issue.
2. The sound persists unchanged even if I'm pedaling hands-free, so I'm thinking it's not a handlebar/stem interface issue. (And probably not headset either.)
3. No change when I'm pedaling while standing, making no contact whatsoever with the saddle or seat post, so I'm thinking that rules out anything in that neighborhood.
4. The click occurs in PRECISELY the same place in my pedal stroke, which would seem to support my assumption that it's something generally BB/crank related.
Assuming that my logic isn't completely off, I keep coming back to my BB itself going bad. The only problem is that I've got a fairly old Campy BB (one of the old AC- or SC- models), so I assume finding a replacement will be a challenge. Does anyone know whether I'll be able to just upgrade to a Chorus or Record BB and still use my existing cranks? My frame is an '81 Colnago Super, so I'm hoping that I won't run into compatability issues with newer components.
Anyway, best of luck. And if all else fails, at least you'll come away with everything on your bike being well tuned and lubed!

|On my Novara Big Buzz city bike, I had the same noise. After a lot of work I found it was the seat clamp. It requires tightining about every 2 to 3 weeks or I hear a creaking clicking sound.|
|no more tick!!!||took|

|Used teflon tape on the BB threads and it did the trick. Snugged everything real tight w/ a big-a$$ adjustable wrench then went out for a ride this morning, and NO TICK!!! sure is nice to ride a quiet machine (even if i did have to take out my bb 3x to get it to shut the freak up)|| |
