    Fatbikes.com SRAM X9 Fat Bike GXP100 Crank

    You can remove the spider and chainrings, then sell them to get money for a spiderless chainring.
    I see hills.

    I want to climb them.

    I have this one. The X9 crank is good but the BB is a very low quality one. A few miles of heavy and sticky mud have broken it. I will change the it to a Chris King GXP one (to keep using the X9 crank) more expensive but the quality will be there.

    Chainline is how far the middle of the chainring is from the centre line of the frame.

    I'll agree with you there. Just a tip though...the SRAM cranks seem to have some bb shell width tolerance (maybe 3-4mm) built in and may require some rubber o-rings between the bearing shield and the crank spider on the drive side to stop the shield from sliding out from the bearing. The shield may not slide out if new, but once you remove it to try and repack the bearing with fresh grease like I needed to, it might not sit so tight again.
