Which cassette?
Discussion
Afternoon All,
Having changed a chain for the first time ever yesterday, I went out for a play in Swinley Forest with a couple of other PHers today.
All went well (and wonderfully silently) until I had to apply any major effort, at which point the chain started skipping rather annoyingly. My first thought was that I'd maybe left the chain a link too long, but another rider who happened to stop in the same place reckoned it was far more likely to be the result of a worn cassette.
Assuming this to be the case, is the cassette easy to do a DIY replace on?
Also, what options are open to me? I'm assuming the current cassette is a Shimano cassette, seeing as all the other chainset components are. I'm looking at the M770 XT cassette which Wiggle currently have for £35, but wondering whether I should be looking at and SRAM products or anything else around that price range? Also, the XT cassette comes with both an 11-32 range and 11-34. Do those extra 2 teeth on the largest cog really make that much difference?

An XT cassette will server you well, not too expensive either. Unless you are looking for ultra light weight I would go for an XT one.
To remove them you need a chain whip and a cassette tool. The wip to hold the cassette in place while you use the cassette tool to undo the lock ring (at bottom surrounding axle).
You can get away with just a cassette tool(special mount), and clamp/ jam the cassette to stop it spinning but it makes for hard work.
I guess you could get the two above tools for £20 for most bike shops, quite common.
The cassette tool normally mounts on the end of a ratchet for easy of use, or has spanner flats.

If you don't know how to make a repair or get something off your bike, try Calvin's Corner on the Park Tool Website:

Calvin was my instructor a Barnett's Bicycle Inst. the first time I attended in 1992, He knows his stuff...
You should always replace chains and cassettes at the same time unless one of them is brand new.

If you haven't got a chain whip you can use an old chain to hold the cassette.
You need the leverage of the steel bar on a proper chain whip.The last time I changed a cassette I didn't have a chain whip and I used an old chain to hold it.
Superman or likes to make life difficult for himself.You can make a chain whip with an old chain (about 8-10 inches in length) and a piece of solid wood as a handle. Just nail the end of the chain to the wood in a few places for security and you're there.
XT cassette is fine, depends what you are mating it with as to whther it's worth it. Maybe a Deore or LX cassette if the rest of the drivetrain isn't too expensive, but the XT is good quality and will last pretty well.
As for the size, well, it depends a bit on your riding style and local terrain. If it's mainly Swinley riding and other local south east England spots, I don't really see the need for a 34 tooth ring. If you're heavily into big hill assaults, then maybe go for it.
If you're a Swinley rider then let me know, we could try and get a PH meet one weekend.

In answer to the compatability question yes you can fit a Sram cassette if you want. I run an XT cassette with Sram X-9 shifters/deraileur no problems, having previously run XTR shifters/deraileur and Sram 971 cassette again with no probs. I always run a Sram chain as I have found them more reliable than Shimano ones - others may disagree but that's their choice.
Campag cassettes are different but as these are road specific it isn't something you need to worry about.

Okay...
I've got the XT cassette from Wiggle.. Why on earth anyone would ever pay extra for their express delivery is a mystery to me! I ordered at 18:45 on Monday evening, and the goodies arrived here at 07:45 this morning!!
...and in my experience, that's actually quite slow for their standard service!I've got the XT cassette from Wiggle.. Why on earth anyone would ever pay extra for their express delivery is a mystery to me! I ordered at 18:45 on Monday evening, and the goodies arrived here at 07:45 this morning!!
I've often ordered one afternoon and received the next morning without paying for the express service.

I've just realised the typo. I ordered not on Monday evening but on Tuesday evening! Assuming they had already gone home by then, and the package arrived before they got in this morning, service in less than one working day is pretty bloody impressive!
