Does refitting a rear wheel slacken the chain...?

If you were happy with the one you have,just count the teeth on the largest and smallest spocket and get the same,the higher the number the longer the pedal stroke,so the quicker you go without spinning out,if thats a problem you have had?

Gotya. I was happy with the old cassette so will get a new one with same number of teeth. Cheers.

You will have noticed the mtb ones have less teeth,or lower number,this is to help get up very steep bits,by making it supposedly easier to pedal,or a shorter pedal stroke,so in the lowest gear,your feet could be a blur almost,but your hardly moving,but road bikes generally dont need that sort of gear.

Yep - all Hyperglide - just make sure you get a shimano for your bike !

I checked the old cassette on my bike and it's a 9 spd 12-26...Can't seem to find one like this made by Shimano for love nor money (from what I can see, they do either 12-25 or 12-27).

What I did find was this SRAM one - will it do?

12 - 25 will do the job fine, so will 12 -27

Er, are you sure you've got this the right way round col?

I guess I need a 9 speed chain, right? (here's me thinking a chain is a chain is a chain).
This one has a power-link...is that the same as the 'super-link' that you mentioned in one of your previous posts? So you can take the chain off for cleaning purposes?

Er mmm not sure now?i mean the largest on the back,and the smallest on the front

Thats the type - good chain that sram PC971 at £19.99

Also try a KMC x9.93 - 9 speed - 13.99 on wiggle -

I've been using the x8.99 (8 speed) chain on two of my bikes and they are good.

The 'link' be it a missing link, power link or super link - all similar - i.e. easy to remove/refit chain for major clean ups.

I've broken one SRAM chain in about 12 years - that's pretty good I reckon.

Excellent info. I'm ready to order the parts now.
I'll be back on this thread with a progress report (or lack of it). Cheers.

Jesus how f*****g tight are these locknuts on the cassette? I have tried and tried and don't consider myself a weakling but it won't budge. Anyone have any tips to shift the buggar?

 

[fossyant]

They should just undo - anti clock..... get a big spanner on the adapter....

 

[giant man]

Well this one hasn't been off the bike in seven years, is it possible it could have rusted on or something? Do they do that? WD40 has been used of course but going to have another go today thanks

 

[giant man]

Right well I finally got the thing off, had to resort to a vice jobbie mind, but I did get it off!!

Most of my bike tools are many years old - they have repaid the investment several times over.

Agree with this. There's very little I can't do on a bike now. It's saved me a fortune in servicing over the years.
