    Idea! double chainring options

    What are the double chainring options I have? Granny & big ring? Middle & big ring? I have the RaceFace Atlas crank (second generation) & an 8 speed cassette. Their site says: RING CONFIGURATION: 24,36 & Bash SR & Bash SR Ring.

    I bought the RaceFace Team chainrings 44, 32, 22 T. According to their compatibility chart, they do fit.

    Thank you

    Your options are to use the small/middle, or middle/big positions. Also, shifting between rings more than 14t different can be problematic.

    In practice, the small/middle works best from a chain-line standpoint, because the middle ring lines up a bit outboard of the middle of the cassette.

    Also, losing the big ring lets you run a bashgaurd in that position.

    People have been converting 3x crank to 2x using the small and middle positions for decades.

    If I were you, I would try running the 22t and 32t rings you have, and if you find you need higher gearing, you can swap the 32t for a 36t, or go larger on both.
    15mm is a second-best solution to a problem that was already solved.
