i mean yea, we can all drop weight to weigh 95lbs. Should we just change this forum to a soyboy forum? Lets talk bike parts...

Haha, fat arse! That was mature and useful, NOT. Or the classic, sell it and buy a rim brake bike. :roll:

The wheels and tires are always the first place to look, as it makes the most difference to ride quality. Your bike seems a mix of high level Dura-Ace and 2nd tier Ultrega so there could be savings there. Weigh everything and make sure your wheels are under 1400g without the cassette and rotors, tires under 250g and tubes under 70g. Then I'd look at titanium bolts, as titanium seems as strong and durable a metal as steel, but far lighter so then I'd look at titanium stem bolts, cleat bolts and seat post bolts, rotor bolts and caliper bolts. After that maybe get a carbon railed version of your favorite saddle.

Helium into the frame, wheels & tyres. Don't forget to refill regularly.
And if you're brave and aren't scared of second coming of Hindenburg go Hydrogen!

Soyboy. Love it. I just had to quote this because it made my day.

I will one up it: dont drop weight, just trade fat for muscle. Maybe that makes me a creatard.

Titanium bolts will save grams. Not worth it. But it may be worth the intellectual masterbation fun.

ashima ai rotors
Deda or Tessa bar tape. Dont tape the tops
Darimo ellipse bars. Something aero if all rou d performance is priority.
Wren stem if on budget, darimo if not
Cane creek aer headset
Extralite or tune gum headset expander
Extralite through axles (tririg if it is quick release)
Wheels. Dont go tubular as the better crr of the best clinchers/tubless will outweigh any weight savings of tubular. (I assume you want the fastest bike, not just light).
Aero wheels while you are at it. They are about 8% of total system/rider drag.
Pedals are personal, but i have the xpedo something or other with the titanium spindles. 160g a pair or so
Dura ace across the board, but ee brakes if you want light, tririg if you want fast. Dura ace if it is a disc brake bike
Thm cranks if you piss money
Bottom brackets are not worth going light... just go dura ace.
Berk saddle if it suits You.
Darimo post.
Carbonworks cages and elite superfly bottles, or elite crono setup if you care about speed

Hey! You offered your weight as part of the list... figured it was fair game. lol

but back to bike parts - saddle? cassette? tubes? <-- about $500 maybe to save 130g?

OK so then just buy a bunch of expensive components and leave 200-300g of economical weight savings on the table because it's just 'intellectual masturbation'. :roll: Seriously you recommend slightly lighter bar tape but sniff at ti bolts? Then you recommend ti axles on your pedals?

In china titanium bolts cost nothing. Like 30cents a pop.

Sure they're not shiny but just as light or lighter even.

Check aliexpress and skip past the shit that looks like jewelry.

Don’t be offended. RocketRacing just gave an awesome list of improvements.

But I am wondering what you are referring to with those 300 grams.

How much you save with titanium bolts if you change seatpost bolts, stem bolts, caliper bolts? Botlle cage bolts are usually alu with better frames.. is there a significant weight saving? 20g? Is it worth changing caliper bolts when you loose Shimano special security bolt?
What about derailleur pulleys?Shimanos are 30g. Extralite makes 10g pulleys, but they are from delrin, a plastic...is it ok or a weightweenie part with special care? Or alu pulleys? They are about 15g, so still 15g saving, but aren´t they loud?

Most of the pulley weight saving is not from the material (with exception of ball material steel/ceramic) but the size of the bearing. Aftermarket pulleys have tiny sealed bearings.

I suggest steel balls, for long life and less friction, because you are much more likely to receive a better tolerance bearing.

Thanks..so it is not worth the tiny weight saving:/
And according to Ceramic Speed data Dura Ace have really good resistance.

What about titanium bolts? Is there any drawback besides money?

You can replace everything except for the frameset, shifters and derailleur(s). And strip the paint. See my signature for an example.
