Clicking noise when in middle front gear

[Belix]

Hi folks.

Newby, still learning the terms so bear with me...

MTB Bike went in today for a new chain and to fix a creak from the crank.

Shop called to say new chain kept slipping so cassette needs changing. Also new cable for rear derailleur.

 

So I get home and take bike for a quick ride. Crank noise sorted!

 

But

Whenever I use the middle (3x9) front gear with any rear gear, I get a similar sound to when the rear derailleur is not exactly in line, except from the front, and slower.

Can also feel it through the pedals. Almost like chain is moving slightly under load.

 

Checked to see if chain is touching the front derailleur, but looks clear both sides.

Since it's a bit of a mission to get it back to the shop, was hoping it might be something that someone has experienced before?

Maybe a bent tooth on the middle chain ring?

If it's only clicking when pedaling...?

Stop pedaling ...

Simple really..

Agree with Patch. Could be broken/bent tooth...

If its a brand new chain with an old chainring, I have encountered this before myself.

Laymans terms is that the chain needs to settle in with the crank chainring thats slightly worn, 1 ride and its usually sorted.

[Heel Drop]

if that does not work MTB is not for you just give the bike away

[mudda]

could also be the chainring bolts that keep the outer and middle ring in place - check that they are tight...

 

Since both sides are clear - also check that its not top or bottom of the front derailleur touching ...

Just take it to your LBS explain the problem. Tell them you will fetch it later. They have seen it all and normally know exactly where to look after taking the bike for a ride.

Actually quite easy to find, check everything between your two wheels. Take it for a few rides and see if the chain settles in.

The middle chainring is usually the one with the most wear and yours could need replacing as well.

Look, the obvious solution is to just buy a whole new bike. Maybe one with 1x11 (no more middle ring worries)

If your wife doesn't believe you that this is the way to go, and you need back up... gimme call, I'll be your wingman anytime!

Lol.

 

Thanks for all suggestions, yes a new bike would be great, right after a new car to carry it on, and a new house to store it in...alas, funds are short.

 

Will check for loose bolts and a bent tooth.

Will see if it sorts itself after a normal ride, and pass the local shop thereafter if I don't win.

There are some hook type things only on the middle chain ring. What are they and what is there function?

 

Would the shark fun like profile of these teeth indicate the middle chain ring is pretty worn?

The chain ring is shaped like that to improve shifting gears. From the second pic, your chain ring does look a bit worn (the shape of the gap between tooth).

Middle chain ring looks a bit worn in my opinion...
