New cassette and chain
New cassette and chain
Hi everyone
So I got my bike fixed the other day and although fixed the tech did mention my cassette and chain are worn and new ones should be considered.
I have an 8 speed cassette and he mentioned that if I get a 34 chain, it would make cycling up hills easier and general cycling easier..
I’m still learning but is this true and are there any disadvantage to getting this larger chain on my 8 speed?
Thanks guys

Re: New cassette and chain
How many chainwheels at the front, and how many teeth on each?
How many teeth on the sprockets at the rear?
Thanks

Re: New cassette and chain
When you're cycling uphill would you like to have a lower gear?

Re: New cassette and chain
He may have meant an 8 speed cassette with 34 teeth on the largest sprocket, which presumably is more than the current cassette.
It would make cycling up hill easier. Only an advantage if you find it hard cycling up hill now with the chain on the largest sprocket and the smallest chain ring

Ok I’m still learning so if the chainrings are near the pedals where the chain goes round then I have two. This is the specs:
Rear Derailleur
Shimano RD-TX800, 8-speed
Front Derailleur
Shimano FD-M315, 31.8mm clamp
Crank
Prowheel TA-CQ68, 42/34/24T, 170mm
Cassette
Shimano CS-HG200 8-speed, 12-32T
Chain
KMC 8-speed
The tech said I could go from 32 to 34 and it may be better up hills..
On the hardest gears it rubs on the front derailleur.
Re: New cassette and chain
Going from 32 to 34 teeth will make a difference but not a significant one. Could try 36 teeth or 40 teeth with a longer cage derailleur. The chain should not rub on a front derailleur designed to work with a triple crank. Some adjustment with the limit screws or the positioning of the FD should cure this.

Re: New cassette and chain
Dev, I've guessed that your wheels are 27 inch or near. That gives us a gear chart as below. I like low gears and my lowest is the same as the one circled. I think your gears are already a good spread for general purpose. Do you struggle up hills? If not, leave well alone is my advice.

Re: New cassette and chain
So Ive just got my head round about everything now lol.
Thanks everyone for all your help.
I will replace the cassette and chain.
Quick question: can I make the bike go faster with certain types of replacements for these two parts? Would 34 teeth make it quicker, or even the quality of the cassette?
Slightly off-topic, but I want to get rid of the rubbing on the front derailleur, which seems to be one thing no tech (had four since I bought it) has been able to crack. Three Halfords ones and the jabberwocky independent tech who bust my gears recently.
No matter what, the chain always rubs the front derailleur when the gears are in their most resistant position (the highest on both sides). Would 34 teeth solve this? As I said no one can crack this.

You can make the bike go faster only by applying more effort

No

Re: New cassette and chain
Do you want to solve it yourself (as linked upthread) or pay someone to solve it? And if the latter where are you?Devz wrote: ↑23 Mar 2023, 2:37pm ...

Thanks for the link, I actually learnt something from it that I didn't know (I've been fitting my front derailleur too high for 40+ years!)roubaixtuesday wrote: ↑23 Mar 2023, 3:16pmDevz wrote: ↑23 Mar 2023, 2:37pm

Re: New cassette and chain
I’m gonna pay Halfords to fit the new chain and cassette ring. I will mention the front derailleur rubbing iagain then, and if they can’t fix it (again) then I’ll try it myself.Jdsk wrote: ↑23 Mar 2023, 5:15pmDo you want to solve it yourself (as linked upthread) or pay someone to solve it?

Weird though as no one can seem to fix this issue. Could be a bike error?
