Hi all
So I bought a beauty of a road bike a month ago.
Here it is
https://www2.merida-bikes.com/en_INT/Bikes.Detail.208

Did 1000 kms in a month. From day one I noticed a clicky noise that came from the left pedal/crankshaft/crank.
This continues to this day especially when I press down hard on the downstroke of the left pedal. Been to my LBS several times. They've cleaned out the pedals, the bottom crank and every thing they could think of. After they tweak with it a little bit it gets better for a while but soon returns. The bike is doing great apart from this.

I am sure with all the decades of experience out there you guys can help!

could be a million things....here's a list to check:

stem bolts (clean and tight)
seat post (clean and clamped properly, greased if needed)
seat post bolts (clean, tight, greased)
saddle (my prolink has a plastic peace that occasionally comes unscrewed and starts doing this)
rear wheel (check spoke tension, nipples, etc)
bottle cages (clean and tight)
quick release connections on the fork and rear drop out (clean and tight)
carbon steer tube (if you have a carbon steer tube check for cracks underneath the head set)
headset (check for tightness)

I say start with the chain rings...unscrew them, clean the threads, then retorque it to manufacturers specs. If it's still making noise, my guess would be the bottom bracket just needs to be rebuilt and cleaned...mine did the same thing, after I took it apart and cleaned it, it stopped.

Thats quite a list. Will get cracking (no pun intended) on it...

I feel for you. I suffered with some bottom bracket noise for about 5 or 6 months, and tried every little thing I knew of to get rid of the noise. Well long story short, we finally got rid of the noise, and it really make me much more appreciate the bike running radio silent.

Good luck.

So how did you get rid of it. My LBS guys opened and cleaned out the BB but its still there!

also, is it even possible to clean an external BB? There's much much there except for the cups?

l was feeling and hearing some clicking noises that sounded like it was coming from the bottom bracket area.
I messed with the seat post, the handlebars, headset, the chain, the pedals, the cleats and even substituted wheels, but I couldn't get rid of the noise. Finally the LBS messed with the BB and the noise went away. It's radio silent now.

I had what I thought was a BB creak that was driving me nuts. I had greased and re-tightened everything I could think of. I took it into my LBS, and the mechanic figured out that the lockring on my cassette was a little loose. problem solved.

Hi all
SO the guys at my LBS tinkered with the bike on several occasions.
We had the BB changed but that did'nt help.
Pedals changed but did'nt help either.

Finally we changed the chainrings and crankset and the noise just vanished.
I now have 105's with a standard chainring 53/39 vs. the compact I had earlier.

Feels great to ride a bike minus THAT noise!

Good deal for the LBS too. Ka-ching.

Had this problem too - next time just tighten the chainrings.

Except when sounded like "A"
As in "neighbor" and "weigh"
