    Vivid R2C Tune Choice?

    Hey all,
    I have a 2006 Haro 357 Magnum that I would like to run with a 2011 Vivid RC2 shock. They come with 3 different tunes High, Low and Medium based on leverage ratio. Does anyone know which tune would be right for the 357 (single pivot)? or how do I find the leverage ratio for this bike?
    Thanks for the help.

    so the bike uses a 9.5x3 shock. It's advertised as 9" travel. 9/3=3 leverage ration?

    Yes. So depending on your weight you'll be on a mid or high tune.

    So wt 160 lbs and with gear about 170 maybe the high tune would be right?
    BTW thanks for your help.

    I would have guessed mid tune at your weight, but I've never tried a high tune. I would call sram, or it might be on their site.
