I got eebrakes in very good condition used for maybe 1/3rd the cost of new. Still not cheap... but i saved a lot of money for callipers with near dura ace braking, and 171g without pads for the pair.

  • Titanium cleat bolts 30-50g?
  • Changing stem bolts to titanium and various brake bolts 20g-40g

These are highly optimistic figures. You'll be hard pressed to touch 25g of weight saving for the cleat bolts.
Likewise for the various screws, brake and pivot bolts. And to clarify, these specialised bolts are not " cheap" per se either.

  • Lighter pump, up to 50g
That's pretty conservative. Cheap pumps and the really light ones can be as much as 200g difference.
Then again, the really light ones are not exactly "cheap" either.

My suggestion -- and I am surprised no one has mentioned it yet -- is to fill your tires with helium instead of air. Helium is lighter than air so you'll save some grams. Plus, you may be able to float up the climbs, ahead of your club ride friends. (Why else do you think Ridley named its climbing bike the Helium)? Also, at coffee stops, you can delight your friends by taking a nip from the tire valve and speaking in a squeaky voice.

If i would see a good price for the ee brakes i would sure buy them... the lowest price i did see was 475 euro used brakes.

Except that you can't use helium on normal rubber tubes nor tyres ....

I'd take the helium idea with a grain of salt Image

Not sure we have to mix “big gains” and “cheap gains”. EeBrake saves a lot but the $/g is not great (150g for 450$ that’s 0.3g/$)

2lo8 who did an interesting zero carbon bike has a website where he listed really interesting savings where 2g/$ is just “OK” and 5 or 6g/$ very good.

I don't run cable adjusters on my bikes, external or internal routings. Just chuck your cable adjusters into your spares box, free grammes saved. Only applicable to mechanical though.
Less is more.

OK some of those postings were guesses, but you also seem way off.
The titanium cleat bolts include the shims for Shimano systems, so the weight is pretty much right.
I live in China and good (and garbage) quality titanium and aluminium alloy bolts are fairly cheap per gram.
Also the pump figure is about right. I own several mini pumps and I actually use my heaviest at 103g, becuase I find it the most use-able, so I have no clue what you are talking about there. Maybe it's easy to find a 200g difference between floor pumps, but not mini pumps.

I suggest that you might like contribute to the thread by posting your own ideas or something someone else has found about cheap ways of taking weight off their bike. Or if you really want to find someone else wrong than actually try using data rather than guesses. We're mostly all here to learn.:thumbup:

Im thinking about buying a smud full carbon saddle... saves around 150grams of my prologo zero 2 pas... someone has experience?
Works fine for me.

But obviously saddles are a very personal choice.
