Ticking noise from drivetrain(5 posts)

Ticking noise from drivetrainkai-ming

After logging 5000km, there are regular ticking noises from the drivetrain at low gears while climbing hills. Do you people think that is from the durace BB ? Should I give it a little service ? If the noise is from the BB, could I get away by just clean/grease or I have to replace the bearings all together ? Thanks for the input.
Likely first place to look is the BBKerry Irons

But it is probably the BB/frame interface, not the bearings. 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. 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, 50 nm for Shimano, 70 nm for Campy, or as otherwise specified or labeled)

the chain ring bolts (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)

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)

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.

I've had two similar experiences--looked all OVER for a "driveline" noise, replaced the BB and chain and everything I could think of. Both sort of came and went, and I couldn't isolate them. Drove me crazy.
The first turned out to be a very slightly loose seatbolt clamp, so under some conditions it would make noise. The second was the tip of my shoelace hitting the crankarm when it came around. Moral: Don't get fixated on the BB.

Twice I have had this problem with two different bikes. Once with a giant hybrid and more recently with my cannondale cadd4. On both occasions the problem was that I had two much pressure on my rear skewer. With the skewer too tight all the extra pressure on the light alum simply seemed to torque the frame. It may sound strange I know but now I always check the skewers first when I hear any kind of ticking.
Thanks, problem appear resolved.kai-ming

I have tightened the cassettes lockring, the ticking is gone this morning.
