Hi Guys
To replace a rear mech ,do you have to remove the chain ,Is it possible to just remove the jockey wheels ,and then take the mech off .
Then refit the reverse way.
Thanks any advise appreciated

    I'd take the chain off because setting up a rear mech to start with is far far easier without the chain getting in the way.
    You only need two tools: WD40 and Duck Tape.
    If it doesn't move and should, use the WD40.
    If it shouldn't move and does, use the tape.

    Depends on your rear mech, some can be taken apart, others are fixed.

    if you break your chain get a powerling to re connect it. Much easoer to refit and you also can take it off with your fingers in the future.

    If the jockey wheels are removable then yes.

    Sounds like hassle to me though - I'd still rather just go and buy a link removal tool - handy to have anyway.
