Admire the enthusiasm. You need to add another 100grams to the Look pedals. That weight is per single pedal. Sorry

[dudemanppl]

Origin is dummy thicc, do like a Red GXP, sand the arms, do some lighter rings, then do Favero Assiomas.

[refthimos]

While the +95g for the Look pedals is a bummer, you could lose 85g with a change to Extralite Cyberdisc. Mine weighed in at 1065g actual weight.

That stem and bar combo is hillarious. 210gr stem and 124gr bars.

[LewisK]

Depends on the ratio, but a 11/25 sram red cassette will save you about 50g

CarbonWorks cages are 8g each

Ditch the out front mount and use bands that tie around the stem, there’s another 25g gone

The chain should be a bit lighter than that, as think you’ve stated uncut length!

Deda do some bar tape around 30g, not sure what it’s called but someone will be along shortly that’s knows.

You’d possibly save 200g ish with a frame and fork paint strip, but that’s quite drastic and you may like the look of the colour as it is.

Deda traforato bar tape
PYC 1101 chain
Speedplay with chinese titanium axles and hardware
You can loose a lot with Hutchinson Fusion 11 Storm Galactik

[WorkonSunday]

KCNC make some of their rotors in titanium:

that will be 20g for the front. dont think they offer 140mm tho.

also RED cassette will also shave some weight over dura ace too

[DanielNorway]

For comparison, my 56cm weighs about 6.94 kg including:
- Full DA 9170 50/34 11-28 4iiii dual side crank, XTR 160/140 rotors
- PYC 1101 chain
- Speedplays 140g
- Antares saddle 140g
- LB46 wheelset 1390g
- Hutchinson Fusion 25mm 260g x 2 + 2x30ml sealant
- Canyon bartape
- Wahoo mount
- XXX Bontrager bottle cages 2 x 20g(?)

That stem and bar combo is hillarious. 210gr stem and 124gr bars.

Not much choice for the stem if wanted to keep the clean aesthetic of internal cable routing.

Can't wait to see some photos of the beast

1150g disc clinchers? Are you super light? But first thing id look at the canyon evo. The frameset has been recently listed for sale, 4k, probably about 100g lighter than the bmc.

[alanyu]

BB: Shimano BB92-41, 54g, and it's much cheaper.
Cassette: ZTTO 11-28T, 177g.
Chain: CP record 11, 240g, or YBN Titanium 11 220g if your pocket is deep enough to replace rapidly.
Tires: Pro one addix 2020 * 2, 520g
Chain Catcher: No need = 0g

I'm not heavy. Partington wheels are listed to be stiffer than Meilenstein and ENVE SES, which I already riden before without issue, so at least on paper there is no flex issue.

Canyon Evo has expose cables. Not the aesthetic I'm looking for. Just personal choice.

THM Clavicula/Tibia/Extralite rings/Cane Creek AER II. Any combo of all might get you to your goal
