  • Is there somewhere that can help me "design" bike geometry?

    I am casually considering a Marino custom fixie, previous experience was with a UK distributor (no longer in existence) who scaled up their default options on the mullet MTB to XXL proportions.

    This time I would be flying solo and starting with no existing data.
    I suppose I could measure my existing bike and try to scale it accordingly?
    (Current ride is a Charge steel number, that runs a decent amount of seat post, and the toe overlap is less than ideal)

    The details I need are in the following diagram, but I don't where to begin.

    Well, I do know where to begin, the worlds friendliest forum!

    I am 6'6" so needs to be big, also the fork will be a custom Marino too, so I need to settle on an appropriate ATC length.

    Finally, the flavour of steel, 4130 is default, 520 or cromor are $20 extra and 725 is available for $60. I know nothing on the variations, so don't know which to choose.

    Rough early estimate on costs would be around $600 / £470 (delivered, but possibly with import fees, haven't looked into it yet)

    Is there a UK frame maker that could knock out a custom steel F&F for similar money? Thinking of this whilst typing out, so apologies for rambling and making a long post.
