    I think its 34.9mm top swing bottom pull (but most modern mechs are multi fit & multi pull) so its just the swing thats important as bottom swing will hit the swingarm when on the big chainring.

    Well I think the Marin FRS are all bottom pull – also you would need the appropriate seat tube diameter which should be 34.9? – you’ll have to measure it with a tape measure to be sure – the 2002 East Peak had a seat tube of 30.0 – very odd old size? So perhaps the front mach bracket should be less thn 34.9mm? Anyone else agree/disagree?

    this is one I bought but just doesnt seem to be any way that it is going to fit. it is a XT FDM771

    well its a a multi fit front mech – I would think therefore you mean it the collar by which it clamps onto the frame is the wrong size – measure the circumference of the tube and that will give you the size – you may have to buy some convertors for inside the collar if its too big?

    It is not the clamp size it is the actual style of front mech I need to know, there is just no space for the mech to fit in above the chain rings. Would an e type fit?

    I don’t think there will be the clearance for the mech you have bought.
    As Snaps said, you’re going to need a top swing, bottom/dual pull mech as the swingarm will get in the way for conventional swing.

    something like this will fit:

    Yep you’ve bought a bottom swing & only a top swing will fit those frames – swap at shop?

    Yup – sorry its a top swing – sorry didn’t realise that was where it “wouldn’t fit” – yup bottom swing, bottom pull – I got one of those off my old marin – I think its 34.9 bottom pull bottom swing – got 2 old LX ones you can haev for very little? PM me if your interested – both in good nick 😉
