:welcome: Is the bottom bracket square taper or Octolink on the bike at the moment.

Mod note - apologies folks, in trying to sort out a new member making double posts, I've managed to get this reply above the post it refers to!

Hello and thank you for taking some time of your day to read my post.

I am new at this, and I am about to fix this parts of my bike for the first time.
This is the bike that I owe:
https://www.cubestorescunthorpe.co....ube-touring-exc-hybrid-bike-in-grey-lime.aspx

After thousands of mile, it comes the time to change cassette, chain, and crankset.
I'm trying to see if the of the pieces I want to buy are all compatible.
This is what I want to buy:

https://www.ebay.co.uk/itm/Shimano-...var=600500163151&_trksid=p2060353.m2749.l2649 (choosing 11-34)

https://www.ebay.co.uk/itm/KMC-X9-9...e=STRK:MEBIDX:blush:T&_trksid=p2060353.m2749.l2649

https://www.ebay.co.uk/itm/Shimano-...e=STRK:MEBIDX:blush:T&_trksid=p2060353.m2749.l2649

Are those pieces compatible with each other?

Thank you again for your time.
Have a good day.

Is your existing crankset Octolink ? If so that should be OK
Cassette is also OK
I am a bit concerned with your choice of chain that says "Road"
Surely there are KMC 9 speed chains for MTB too ?

Perhaps this

It would be interesting to know what bike it is and what front and rear mechs you are using

Hello, The bike model is this one: https://www.cubestorescunthorpe.co....ube-touring-exc-hybrid-bike-in-grey-lime.aspx

My concern with the chain it's where it says 1/2" x 11/128" as the cassette is an 11-34T. Again I'm new at this so I'm not entirely sure if they are referring to the same thing. Apology for that.
The chain says Road/Mountain Bike so I guess should be ok for mine that is a kind of a hybrid.

The Cassette and the Chain look good. But that crankset you've linked to is Octalink, and i think yours

is a Square Taper.

Chain is fine then - but as mentioned your crankset option will not fit as your existing setup is square taper not Octolink.

I see, thank you both for the heads up.

So something like this would be ok?
http://www.ebay.co.uk/itm/Shimano-A...302111?hash=item3f6f4db09f:g:SkgAAOSwo4pYKtYH

A few more question if I may: What those numbers are (48/36/26)? and what do they mean? Do I need to get a crankset with the exact numbers?
Same question for (175mm), Can I get a crankset with 170mm instead?

I appreciate what you doing thank you again.

That's a better one

The 48/36/26 mean the largest cog has 48 teeth, the middle has 36 teeth and the smallest has 26 teeth

I notice you have a chain guard on your existing setup.

Make sure a 48 tooth one will fit before buying - count the teeth on your existing one to be sure

Forgive me for asking but why do you feel the need to change your crankset? Entirely reasonable to replace the chain and cassette (9sp) after "thousands of mile(sic)" (I did mine last week after circa 5,000km) but the chain rings are unlikely to be worn (for example mine (9sp) have done over 30,000km and still fine).
If you judge one or more of your rings are worn, replace that/those (probably BCD 110mm).
If you want to change the chainset (cranks and rings) then the replacement needs to be one compatible with your bottom bracket (details below).
Spa Cycles do an excellent chainset (in their 'offers' at present - £35) in a variety of crank lengths (I have recently got one with 165mm cranks) which I think will be compatible with your BB and chaincase. They are very generous with their advice as well so call before you buy - their advice will be more assured than posts on here.

Hi, Thank you for your post. Of course, you can ask.

I decided to change the crankset entirely because when I stop by the bike shop to see what the problem was (and see how much they wanted to fix it) the guy told me that I needed to change at least the middle ring as well as it was worn out. At that point, I thought of buying a new one entirely and start over from scratch and be more considerate and check the chain more frequently. I think now I'm going to start with the cassette/chain and the middle ring only (if really needed) and try to keep an eye on it.

I am glad to have found this forum. You guys are amazing.

Post a picture showing some of the teeth of your middle chainring and experts on here will give you an opinion, to complement that of the bike shop chap, as to whether it needs replacing.

Hello guys,
At the end, I changed the cassette and chain only. In this other place where I went (which for £6 per hour they rent you a workplace + tools and advice/help if needed) they told me that the middle ring is yes worn out but that I can still wait before replacing it.
Now I have to stay alert for when that time comes. Need to check more often the chain too.
I'm glad I started to do this kind of work by myself though, it gives you a certain satisfaction apart saving a substantial amount of money.
Once again, thank you all for your bits of advice and patient.
Ride safe!
M
