OK, as a new WWer, I am a bit disheartened now.

Basically I took a $4300 stock bike from one of the bigger names w/ XT/XTR, etc., upgraded a few parts here and there, and still ended up at 11.2kg. And I see you guys do 8kg Hongfu's left and right. So it is a bit tough to swallow.

My catch is this though -- I am a relatively powerful guy so I am not sure I should go near the KCNC's of the world.

Here are a few pics. The front der will come off but that won't change much. What do I have to do to get down to reasonable territory without blowing another few grand?

How about a spreadsheet with part weights? :wink: You can start by checking mine out, maybe it will help you towards the desired direction.

Dude you still have the spoke protector on and you come here with "make my bike lighter"?

My suggestion is to go ride, 11kg is fine for riding.

Also, did you notice you are running 1x but you somehow forgot your left shifter, cable and front derailleur on the bike?

Ok, I fell for the trolling :(

Already addressed this point in the original post, as I am experimenting with the 1X system so the front der will come off for sure.

Re the valve cap, thought it's orange and an interesting to match the graphics. Plus, is it even 1 gram?

Pretty cool. Thanks for sharing. It's more impressive when you start off w/t a 2kg frame.

Those are... interesting grips...

Also wheelset. And are you still running tubes?

Pretty much every component on your bike has a lighter, just as reliable, just as string replacement.

I’d make a spreadsheet with the weight of each current component, each ideal replacement component, and the cost.

Figure out the grams saved per dollar. Hint: more is better. Hint #2: Wheels, bar, seat, stem are the easy, low hanging fruit. You can probably knock most of 1kg off the bike there. For a thousand dollars or so.

Basically, starting with a heavy bike and trying to make it lighter is an exercise in futility. It can be fun, but it doesn't make sense.

Either start a new build and compare weights from the start, or just upgrade functionality where needed and use lighter parts in the process. Even if you manage to save 1kg the bike won't feel much different, or be measurably faster.

Only exception: You could get a set of superlight tubeless tires for dry conditions - that will really change how the bike feels.

Something on the relevance of weight...

Hmm 11.2kg seems unusually heavy. Have you checked your scales.

My latest buuild, 29 in large carbon frame weighs in at 9.55 kg inc pedals.... Ofcourse it could be that my scales are wrong. No extreme ww parts but a smattering of cheap Chinese carbon and some ti, rs1 forks limit wheel choice so the wheels are not as super light.

Those wheels are really heavy.
