old parts as they come off
left crank - 427 g (hdl 170)
crank bolts - 15 g (yes, swapping them, a whole 4 grams!)
right crank w/drive sprockets - 983 g
bottom bracket (not planning to swap immediately)
handlebars - still on bike, don't want to start them until i have everything. rather than order a set on amazon and wait for delivery, i broke down and bought a set of what passes for thumb shifters at the local shop. don't think they'll fit well, may return them.

and the total difference for the cranks, (drum roll, please)

left crank - 427 - 233 = 194g
crank bolts - 15x2 -13x2 = 4g
right crank w/drive sprockets - 983 - 643 = 340g
total weight loss for cranks = 538g or 1.186 lbs. not very substantial. we're still a 28+, almost 29 lb bicycle

eta, for posterity's sake: the change from 48 to 50 teeth on the big chainring gives a small but perceptible increase in speed, or at least the feel thereof. i may look into going up to a 52 or 54. i'm hearing that 52 was standard on the vintage peugeot 10 speeds back in the day.
more eta: LBS shifters wouldn't go on the new handlebar. returned them. 20% restock fee. !@#$

next up, because i have everything, tires.
there's a lot of talk on the internet about how changes to rotating mass, i.e. wheels and tires, give a disproportionate effect on felt performance. then there's tread, which has an effect on rolling resistance. since mr. falcon was kind enough to include a pair of Chao Yang 25-622 tires from the Hang Zhou Rubber Factory to replace the (nameless?/WD?) 32s that came on the denali, it makes sense to weigh and swap them. the 25s together weigh 658 grams, just over a pound for the pair, why bother? there's some error, as individually they weigh 338 and 322, for a total of 660. 2 grams total difference, not much in the scheme of things, some sort of measurement error i assume. more significant, the difference between the two is 16 grams, about 5% of the heavier tire. so there is variance within a make and model of tire.
i'll pull and weigh one of the 32s currently on the bike in the next couple of days and we'll see how much there is to be gained (or lost) here. if the difference is some small fraction of a pound, i may put the 32 back on and call it good for now.

I just weighed the stock red stripe no name 32'st that I pulled off my Denali. 1.25lbs, which converts to 567 grams.
They have low miles, and the rear has a little wear, but the front doesn't appear to have much at all.

is that 567g for 1 tire or 2?

Oops sorry. That's both tires combined

no need to apologize. i think there's been a serious lack of precision in the denali-mod weight discussion, and frankly i'm having a little trouble with the concept that the 2 stock tires weigh less than the 2 25s :shock: . maybe i'll go ahead and weigh my stock tires anyway, just so the numbers are all from the same scale.
i'm not seeing where anyone could get 10 pounds off the denali without spending a fortune on carbon. these replacement parts i'm weighing are not necessarily the lightest, but so far the best i'm getting is a pound here and there. maybe 5 altogether. maybe. we will see. i've still got the handlebar and fork to look at.

Good plan. My scale may not be calibrated.

i calibrated my scale the old way. a US nickel weighs 5.000 grams (and has since the mid-60s), and a penny is 2.50 grams.
