    Trying to set up gears on a parts bin special.

    Got a crankset which needs a 110-113mm bb to make a 47.5mm-50mm chainline (Shimano M440) so I have a 113 spindle bb…

    I also have an old (*old*) front mech (shimano fd739) but I can’t get it to reach the big ring.

    Am I missing a trick or do I just need a newer mech? Tried adjusting the limit screws and its just not happening.

    No such thing as a “boring” bike build question!

    Probably new mech time, older types were set up for a narrower chainline than the modern ones.

    Cheers. New mech bought. All working well except…setting up the rear derailleur is hell. Never done it before. Wish I kept it SS at the moment!
