How to Fix a Clicking Creaking Bottom Bracket || Triban RC520 Service 

Thanks for the comment. Yes, I've heard new bikes aren't necessarily immune to these issues. Hope you get them sorted. Happy cycling!

Hi. That's a fair observation. I mentioned in the video which of the 3 parts I 'serviced' I thought was the likely cause but you're right without testing after each one it's not possible to be 100% sure. Gives an idea of the main things to check though (I hope!).

@@onemorecyclist Agreed. Some people just want the noise to stop and care little about what was causing it. The analyst in me wants the issue solved, but he also wants to know what was causing it as a data point for solving it again or for preventing it from recurring.

I changed bb and the noise are gone, but new noise from pedal after couple months

I used a Shimano Tiagra RS500 as the replacement.

I'm running 700x32/622x32 Schwalbe Marathons. No probs with mudguards on but not sure how much bigger it's possible to go and still keep the mudguards. 37 might be possible. Let me know if you try 37 and it works. Remember you need a bit of room for any debris that 'sticks' to the tyre and runs inside the guards before coming off. Thanks for the comment and happy cycling!

@@onemorecyclist do you find 32 comfortable enough? And enough for light gravel? 🙂

For road cycling/touring I think they're perfect, yes. Light off road (access roads and canal towpaths etc.) they are fine but if I did more riding on these surfaces I'd go with a larger tyre for sure.

@@pjinkilas bro I run 700c x 25 Continental Gatorskins at over 100 psi and I bomb it over pot-holed gravel paths, down muddy forest tracks, as well as hammer it on the road... is it theoretically ideal? Probably not. Does it work? Heck yeah it does, and it's a ton of fun too. To anyone worried about tyre dimensions and rideability and all that I say forget about all this stuff and just get out there and smash it with what you can get your hands on as long as it works! Shiny side up and have fun!

It's often hard to identify exactly where the noise is coming from, isn't it? The only other things that spring to mind (as well as what I covered in the video) are wrong size chain fitted or seized link somewhere, bent derailleur or front derailleur rubbing (i.e. needs adjusting). Finally make sure the chain is threaded properly through the rear derailleur as if it isn't you can have metal on metal rubbing there. Hope you get it sorted and happy cycling!

Did you fix yours? I have the exact same issue after the same km as yours in dry condition...

If it's a gritty noise, the bearings could be gone. Try and spin them with your finger and see if it spins smoothly or if it's rough.

It's a few years since I bought the tool - think it was this one - amzn.eu/d/03VDgVtK

@@onemorecyclist Thank you very much!!

Hi. Thanks for the comment. Unfortunately I'm not with the bike at the moment (to see if there's any identifier on the part) but I think it's a Shimano Hollowtech threaded BB. Decathlon might confirm the exact part/part no. if you dropped them a message.

@@onemorecyclist no problem, I found the correct part number. Did you sell the bike?

No I've still got it.

@@Ryezn5057could you share the part number?
