Cassette replacement or replace a few sprockets

sextoke1

Hi All,
Just wondering, instead of changing a full cassette for say CS 6800 for €50, one could replace the four smaller sprockets (11T to 14T) for about €30. Would did be a good idea?

Yes. Cogs wear out at different rates according to cog size and rider use. I've always hated having to replace an entire cassette due to maybe only two cogs being worn, very wasteful. The availability of separate cogs seems to be going the way of the dinosaur as of late whereas years ago they were fairly common.

Are your smaller ones more worn? I tend to find it's the middle that wears out first.

You could always do the unthinkable and buy a complete 105 cassette for as little as ~£28, depending on what ratios you want.

True enough. I would suggest either saving, selling or donating your good cogs from the old cassette though. Just hate to see people binning salvageable pieces from old parts. Only difference between the 105 and Ultegra is very slight additional weight which most don't care about. Durability and performance are the same.

I must check my old rear sprockets, to see if it is the smaller ones (11t to 14T) or two or three in the middle. Ether way, the question is does anyone just chage a few sprokets and get an extra one or two life cycles out of the cassette. You may have to change different sprokets the next time dependent on winter/summer riding....For the recorder, I normally winterise my bike. winter crankset,winter cassette,winter brake shoes & pads,( same parts as the summer) winter wheels.(Mavic kysrium elite in the summer, Fulcrum cx lg Quattro(in the winter) new chain, new jockey wheels,(twice a year on the change and if needed in between)

It is a techinal question, not a monetary question.

Back in the day I would put bigger sprockets on for hilly rides. But we had less sprockets to play with then so we had to choose carefully.

It does depend what gears you use I guess ? I wasn't aware you could get individual sprockets now. If you fancy it then go for it.

The normal sites like Wiggle and Chain don't do them. They are other sites where you can get nearly any little part for Shimano, Some of them have access to the whole range of parts.

Try going to your LBS. Some will order them for you if you're nice and provide them with the part #'s.
