    Pulled the Trigger - Upgrades

    Ordered a DaVinci Crankset

    53/42/30 chainrings

    172.5 mm Captain cranks
    170 mm Stoker cranks

    Chose to order IRD Quad QB55 bottom brackets.

    Spindle lengths
    107mm - Captain
    115mm - Stoker

    This is on a 1990 Santana frame with 140mm rear-spacing.

    Also, ordering a Campy Comp Triple front derailleur.

    Make sure you have the right size crank bolt wrench in your pocket or on your multi-tool when you head out for your first few rides with the new cranks and BBs. The daVinci square taper cranks have a tendency to work loose when they're brand new. At the first indication that anything might be amiss (a strange feeling usually on one of the left-hand cranks), stop and check them all. It's also a good idea to check them after each ride for a while.
