It's fun thinking about lighter weight builds... but forgive me because Bill's already posted about all the bits and pieces that in sum can add/subtract weight. But you said a WI bottom bracket (roughly $100 more than normal BBs) is 'expensive'. There's no magic affordable weight savings when you're looking to drop 3/4 kilograms. Just sayin. RH cranks, Hunt (or similar DTC) wheels, perhaps RH tires, ti version of the B17 you already love... these are the big 100g, 250g, 500g weight savings you're looking for. But big changes cost real money. Differentiating the weight of inner tubes, bolts, spacers, chopped seatposts, is just pissing in the wind in comparison to your goal.
If you're not a Clydesdale, then wise money is on lighter wheels. If you're not a home wheel builder, and not stuck on 1980s (and US hand built) wheel dogma, then IMHO you should be shopping Hunt 'Superdura' wheels (their heaviest alloy rim brake wheels, wide'ish, still under 1600g) or something comparable. They're regularly discounted. I wouldn't ride your old heavy wheel weight unless I was pannier touring. Or you could lose half *less *weight than Hunt wheels by economizing on Ritchey Zeta Comp alloy wheels (hand built/signed by talented wheelbuilders in S Korea) at half the cost of Hunt (if you wait until the next time that Performance discounts the Ritcheys to $250, as I did for my daughter's bike on Black Friday).
