    50t clearance on Cross Check?

    I am thinking about turning my CrossCheck into a fixed gear for the winter, too mix it up!
    I have a FSA 50/34 crankset (43.5mm chainline).
    If I want the chainline to work out, I will need to put the 50t where the inner ring currently is (making the chainline about 41mm).

    Will a 50t clear the chainstay? (sorry I can't test this myself, since I don't have the chainring tool yet)

    From the Surly website:

    Chainring clearance- Manipulated stays so you can fit the size rings you want. Go nuts

    I'm sorry, I'm not that familiar with frame nomenclature, what does that mean?

    On the inner ring location? I know Surly's site says 'go nuts' but there's practical limits to this.

    Why don't you
    1) measure the distance between the chainrings (not just the gap, but the gap + the thickness of one chainring)
    2) mount the crank with the 34 and 50 rings on it
    3) measure the gap between the 50t chainring and the chainstay
    4) If the measurement from 1 is less than the measurement from 3 then you're good

    What cog would you use w/ the 50t chainring? Can you get the same ratio w/ the 34t chainring and a different cog? For winter use I am thinking you would not want that high a ratio to require the 50t ring.

    The 50t does fit at the inner position of a compact dual-ring crankset.
