Chainring and Cassette

fonsde

Hi I have a carrera subway 2 mtb that i think both cassette and middle chainring need replacing.

Can i only change the middle one? And how can i pick one that is compatible?

Same for the cassette can i buy a cassette removal tool and the cassette and easily replace it myself?

thnx in advance

Yes mate, either search the cycling web sites or ask you local bike shop to order you one.

You need to get a ring that is for the right chain size (8, 9 or 10 speed) and has the same bolt pattern as your existing ring.

Yes, you need a casette lockring remover like this: http://www.chainreactioncycles.com/cycl ... p-prod7975

And a chain whip (holds the cassette in place while undoing the lockring) like this: http://www.chainreactioncycles.com/x-to ... -prod10184

You also need a big wrench to turn the lockring remover, you might already have a big adjustable which will do the job fine.

If you are changing chainring and cassette you also need to replace your chaing, otherwise a worn chain will jump very badly.

I should add, depending on what level of chainset you are running, you might find it to be more cost effective to buy a complete chainset than individual rings. I bought some rings recently and even reduced they were about £20 - £25 each.

You can probably get an 8 speed chainset for about £30 on the web (chain reaction etc.).

Looks like you use cogs 3, 4, 5 and 6 as well as the middle ring mostly!

for cassette should i go for the

or the

also should i prefer 30T or 32T, I guess for the road 30T is better right?

thnx for all help

I'd get it from Chain Reaction for £7.99: http://www.chainreactioncycles.com/shim ... -prod68154

You can then choose whatever size you fancy.

It will work fine.

fonsde

last question.

you think i should go for a more expensive one?
or that is just fine? (road use)

if yes which? (+-£20)

cooldad

I wouldn't. Deore are pretty tough.

fonsde

apparently the chainring doesnt fit right

its 1mm bigger near each hole

File

fonsde

will shimano m510 deore be compatible?

The Rookie

Be compatible with WHAT? You haven't told us what you have.....

Just file the tabs and fit, common issue with Truvativ cranksets.
