    Niner One 9 BB chain length range question

    New to using a bio-centric and need to slap a chain on my new steed.

    I'm running 34 in front and have 16/18/20 for the rear options.

    Can I set-up the BB placement and chain length to accomodate this range of ratios?

    Figured I'd ask before I start the trial/error process.

    2 cogs wouldn't be an issue, but curious if the 16-20 would be a problem.

    Thanks!

    The jump from 16-20 will probably be too much. However, if you are running a SRAM 8-speed chain, you can pick up an extra power link and add/remove an extra bit of chain when you want to swap out on the rear cog. That's what I do anyway. I have never broken a powerlink, and I break lots of stuff.
