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.

Should have all this stuff for next weekend

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.
