Metallic Click in Drive Train
I have a click while pedalling, but only while standing up. While sitting down, it does not occur.
This click occurs when each pedal is on the foward stroke and parallel to the ground. At low spin rates in is a single click, and at higher spin rates it is a double click.
This click is much louder for my right pedal(on the drivetrain side).
I hit a pothole a couple of days ago, which is the only event I can connect this to.
The click occurs in all gears, and does not appear to be the chain against the front derauler. Shifting is still ok and the same as before the pothole. The frame does not appear to have any cracks anywhere.
Any guesses? Maybe the bottom bracket?
A couple of possible causes.
1. Chain ring bolt is loose. It only clicks under hard pressure like standing
2. If It happens when the cranks are at the 3 and 9 position, make sure the front derailleur cable is not hitting the crankarm as it passes. or... the front derailleur cage is hitting the crankarm as it passes. Try riding in the smalll ring and see if it still occurs.
3. Front skewer is loose
4. BB is loose or worn
5. Saddle rails need greasing
6. Pedals need servicing or tightening.
7. Headset needs adjusting
I'm sure there are more, but check these out a possible areas... One word of advice. Only make 1 change at a time or you'll never locate the source..
I'm guessing BB
A common problem is a BB that has dried out (not enough/too old grease on threads) or inadequately torqued. That said, 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, which can be quite high), crank bolts, 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), 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.
I'll bet more of a "ping" than a click...
A) Noise began after hitting a pothole

D) Most likely your rear wheel has a loose spoke(s)....
Take a look at the wheel truing, and check that the tension of the spokes
is pretty much equal for each side... i.e. all drive side spokes should be approx. the
same tension. The non-drive side spokes will be different tension, but all the same on
that side as well... Also check tire sidewall, which may show where the rim got hit...
I think Spokes
I had the same issue a few weeks ago. Before adjusting spokes and if the wheel is true, place a drop of triflow at each spoke crosssing and at each spot where the spoke went through the hub and rim. Left it over nignt and wiped off the excess. No more noise.
