Hi!
I bought an Orbea Terra H40 Gravel bike 2 months ago. I have driven 1446 km with it so far. I've already had a mandatory service with it, and I make sure that the chains, etc., are professionally cleaned and oiled after every major trip. however, when I turn the pedal while driving, it makes this noise (I don't know which part and what can cause it). At the moment, due to the summer season, I can only take it for service in 1.5 months, which unfortunately is a long time. Does anyone in the group have any ideas / tips as to what can make this sound? What could be the problem? thank you in advance for reading my message!

this is a worn out bottom bracket, you should replace it
Do you have 2 gears in the front? If so, you might need to ‘trim shift.’ This means that while you’re riding in a higher gear, you make a minor adjustment to the front derailleur to eliminate any clicking noise.
I think the sound is similar with mine, although not as loud
I assume the sound goes away when you are not pedalling and just coasting?
How new are the pedals? Have you ever serviced them? Did you move them from an old bike? Spin them by hand, do they feel rough? Do you have a second pair of pedals to swap on for a spin around the block, try that. It’s easy and quick to try.
Step 2: move the chain off and spin the cranks, how does the BB feel? I had a weird sound only when I pedalled this year and it was my BB. Yours is so new that hopefully isn’t it.
Third would be saddle creak, does the sound disappear when out of the saddle?
Does it appear when you’re out of the saddle? Can’t eliminate anything when it comes to sounds. Maybe seatpost or saddle from you butt movement? Alternatively could be rear wheel hub for reasons unrelated to your butt.
I have the same bike and had a similar (and maybe the same) problem. It turns out that one of the chain pins was protruding a tiny amount and creating the clicking noise. I thought it was a bad bearing but a very simple fix. If you let the side of the chain pass through your fingers, you will feel it. Good luck.
Time to adjust and clean your rear derailleur.
Loose rear cassette?
If you are older than 28 y/o it’s probably just your knee. It’ll be fine
I’ve had creaks/clicks like this many times… The causes were:
– Loose chainring bolts
– Loose crankarm
– Loose pedal in crank
– Bent chainring tooth
Basically I would check and re-torque everything in the crank/pedal/bb area and reassess. If that doesn’t work then move on to seat clamps, saddle rails, derailleurs, etc.
Possible crank arm hitting the shifting cable as it comes around.
Take off pedals and clean the
I know this song, it’s the front derailleur cable that be hitten by your crank
Start with the torque adjustment on your seat post clamp
I’m guessing it’s the front derailleur shifter cable hitting the crank arm each time around.
Seat post rail, chainring bolts, cleat bolts, BB, spoke hitting hydraulic hose, dent in brake disc. Since you shifted weight during the video I think it’s probably not the seat area. Look over the chain and make sure there isn’t a link that is very tight, much tighter than the others.
Cable slap – my giant does the same thing. Haven’t fixed mine yet. But think the cable in the down tube is hitting the water cage bolts.
Pick up the frame and give it a good left right back and fourth and see if the sound appears.
Potential fix is to pull the internal cables out of the frame at the front and put a zip tie where they go in the frame so they can’t have slack in the down tube.
Took my bottle cage off and no slap…
Can you feel it with your fingertip while you ride to work out where it’s coming from?
Check your derraliur hanger, remove it, clean it, put some grease in it, same with seatpost and saddle rails and clam
That’s your blinker
