i have an 84 Raleigh Corsa which is partly modernised as my winter ride
its currently running sora 8 speed shifters and has an old 7 speed rear wheel
all shifting if fine but being used to a compact and a nice rear spread of gears im feeling the strain on this standard with a 13-21 rear spread

guess its cheaper to put a new freewheel type cassette on . i can see them on ebay with 14-28 for about £9 delivered. will these go straight on my bike and work ??

is it just a case of making sure chainlength is ok and away i go or do i need to match it to my shifters, or hub of something?

cheers

    If you have a freewheel then you can not use a cassette.

    have a read

    if you can find a 14-28 freewheel then yes. some tools are needed such as the correct tool to remove your old freewheel.

  • i may have not explained well but yes i do mean swapping a screw on for a screw on.
    not a cassette.. as i know they need a freehub

    Yes, that'll be a straight swap. Hardest bit might be getting the old one off. Stick the tool in a bench mounted vice or a workmate. Engage the freewheel fully in the splines. Turn the wheel anticlockwise to unscrew. Much easier if the fully inflated tyre is still on the wheel.
  • thanks chaps

    i guess il make sure i can free off the old one before i go and buy the new one

    cheers

    Just to add to this, be careful doing this as the amount of torque you can exert is massive. I saw a mate snap four spokes as he gave it the big one trying to get a block off an old wheel.
  • Two ways of freeing a freewheel i use, depending on what i have round me...
    A vice ? Clamp the removal tool upright in the vice, slide the wheel on and use the rim 'steering wheel' style to undo the freewheel. You can exert a lot of force this way.

    Or..wheel out, lean over the wheel from the non drive side and using a good 1/2 inch ratchet on the removal tool, lean heavily on the rim while undoing the freewheel...leaning on it holds the whole lot steady and firm.

    Some are bloomin tight, some are ok...i snapped a brand new Shimano branded remover once.

    Your chain is likely to be too short, and if it's worn it may not like the new freewheel anyway, so I'd probably save the bother of finding out and just fit a new one.
  • the chain is only 3 months old but at the price they cost id probably just change it anyway.
    just wondering on the quality of the ones on ebay.. wonder if its a better idea to take original chainset off and replace with a compact

    When putting the new one on apply coppaslip first (or similar product) this will help when it comes to remove again.
