    Replacing Alivio Gears

    Hi all,

    I have a 2002/3 Specialized Expedition Sport that came with Shimano Alivio gears front and rear. It has 8 gears on the rear and 3 on the front. I have hardly ever used the front set at all (only really to go down steep hills at speed), so I only really use only the middle sprocket and it is in pretty good condition. I understand that there is little to choose between basic front dérailleur units so I don't think I have to change it.

    The rear is a different story. While the rear dérailleur unit looks straight and seems undamaged, the gears themselves are hooked, worn and some of the tips have broken although it all still works ok. So I'm looking to replace the gear cluster (cassette?), the chain and maybe the rear dérailleur unit too. The shifters are thumb push type but I can't work out which ones they are. Specialized seem to use a few different ones on the same model bikes!

    Anyway, I understand that the Alivio is a low end product and it might be best to go up the range to maybe "Deore" or "Deore XT" (?), but then I hear things like long cage and short cage and the huge list of different models and gear ratios available.

    So 1). What is a good replacement for the Alivio?
    2). What do I need to buy (jargon time lol)?

    I use the bike for general commuting, getting about town and sometimes some "green" miles along country lanes and fields and I am on a lower budget rather than a big one!

    I have Alivio on my '96 Jamis Durango (7 speed) and it's been zero maintenance (aside from the natural wear items). Low end doesn't necessarily mean poor performance.

    I'd just go ahead and replace the cassette and the chain.
    This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.

    I concur, just replace the chain and cassette. You could buy a Deore 8 speed cassette. I recommend Sram chains btw.
