    Truvativ Howitzer

    Hey guys,
    Im going to run a 1x8 on a current fs build. Im planning to use a truvativ hussefelt and a howitxer bb. I have no idea what size BB i need. I was told howitzers work with 68 and 73, but there are other sizes EX 68/73-56. What does the fifty six stand for? How do I know what kind I need? Thanks in advance

    The standard chainline is most 51mm, measured middle ring to center of seattube.
    You plan to use a chain guide of any kind? Check the manual of the guide, some guides
    need a longer spindle, if you use 1 "big" ring? There is sometimes not enough clearence
    at the chainstay.

    OK e13 and Blackspire are very nice, but much more expensive
