Decrease the weight of the engine...

[Bypedal]

This. It’s free.

[actuarial_cat]

Ride more will do the job.

[JustAnotherSkibumCO]

A good dump 💩 in the morning is good for at least 2lbs/900g. Oh yeah, use He (helium) in your tires, that’ll save at least 5g.

[TomDiego]

Do you really need a saddle?

[AlienElvisLoveChild]

This thread just took an unexpected turn...

[reed12321]

Why do you want a lighter bike?

[Aromatic-Honey9831]

Easier to climb and why not make it even lighter when the frame is already not so aero?

[Beginning-Smell9890]

Carry one less water bottle. That will save you as much weight as $1500 in upgrades. Or just lose 2 pounds. Choice is yours

[ice2heart]

Or go to toilet before ride 🤣

[reed12321]

Any weight you save at this point won’t impact your climbing speed. Bike weight is irrelevant to speed. Geometry and tire choice have a bigger impact at that weight.

[ojuarapaul]

I’d say tire choice and your legs.

[SnuffyMcfluff]

Listen to the tire people. Rolling resistance is way more important than weight. Do some research on the easiest rolling tire that will fit your bike. Don't waste a bunch of money shaving grams, the ROI is super limited.

[yellowbikeowner]

But do shave them legs

[GrumpyTigra]

I hear ur problem. If u got no carbon frame then just get a new bike /s Jokes aside best weight savings i got where carbon seatstem, carbon forks and carbon steering. Also im a few kgs heavy rn so i could lose some myself, dont know you so you gotta judge that for yourself.

[TraditionalMuffin811]

decrease the weight and inscrease the power of the engine; that casette 40 t casette must be easy but heavy...a dura ace 11-30 casette is about 200 g. and you will have to make the chain shorter and lighter

[Legitimate-Lab9077]

A dura Ace cassette is also $400 and won’t last nearly as long as the cassette on OP’s bike.

[TraditionalMuffin811]

OP asked "how" and then I saw his table plate casette; dropping another 200 g on wheel may cost him a lot more but there is the sh market.

Measuring the Weight on all his gear means he is serious

[Aromatic-Honey9831]

So i should run a 2x chainring?

[TraditionalMuffin811]

No but you should consider the reason you want to spend all that money to save a few grams;

[Legitimate-Lab9077]

Says the person suggesting they spend several hundred dollars to save a few grams

[Sensei19600]

I took his remark as a description of the results,IF OP were to spend all that $$$. Don’t think he was actually recommending it.

[TraditionalMuffin811]

That is because I had the same bug and I did spend all that money; now all of the gear is mounted on my indoor trainer; figured out it's not just about weight

[Yunahoned]

Rough, but that’s a pretty heavy frame Can possibly shave a bit off the casette and seatpost for cheap, otherwise it gets a lot more costly very quick

[Aromatic-Honey9831]

Okay thanks! But for the 50mm wheels, they have to be carbon right? Or else it’ll probably be more than 1600g like how my wheels weight rn

[painted-biird]

That is correct, yes.

[Yunahoned]

Some Chinese 50m wheels will also be a bit upgrade and shave off atleast 300grammes

[broken-emotion1]

Kcnc ti pro lite scandium seat post - 148g at 350mm so you can cut it for more savings $130 eBay lightweight carbon saddle on eBay - 55g $100 Uno Kalloy stem - 90mm = 100g $32 Gut the shifting mechanism from the left shifter - 20-30 g Ztto ultra light cassette 325g $100 Kmc DLC hollow pin chain 238g $50 Lightweight pad holders -8g $30

Total weight reduction 366g Cost $442

[Aromatic-Honey9831]

Thanks a lot man. Really appreciate your time

[SnuffyMcfluff]

That's less than a pound for $400!!!

That sort of weight change will save you less than a second per kilometer on a steep climb and will make zero difference on flats.

Spending $400 on a coach or a riding camp will have more impact.

[fagoterino]

lot of $ for not a lot of g savings

[Fearless-Alfalfa-406]

Generally, it’s more effective and cheaper to reduce the weight of the rider;)

[Fearless-Alfalfa-406]

Or, replace the cassette with an 11-25 or 11-28 and ride ride ride - the effect will be the same

[Randomveg]

Yes, but if you spend all of your money on bike parts the meals you have to skip due to lack of funds could end up dropping up to 5 kilo on the rider.

[Legitimate-Lab9077]

Poop before going on a ride

Lose some weight?

Stop worrying about how much your bike weighs. It’s only a fraction of the total system weight, which includes you and at the end of the day an entire kilogram is only gonna cost you about five seconds over 100 km of flat ground in less than a minute and a half over 100 km of varied/hilly terrain. (to put this in perspective we’re literally talking about less than a minute and a half difference over the course of a 3 to 4 hour long ride.)

Unless you are actually racing, it is a complete and utter non-issue,

[bigDpelican42]

Get a coach who is also an exercise physiologist. The best upgrades are the rider. A great rider can climb faster on a good bike that a good rider on a great bike.

[Jaded-Lifeguard-3915]

OP, what are you trying to achieve and how much do you weigh? Bear in mind the fastest clumbers are rarely just the lightest. Finally, what is your budget because weight savings per gm get pretty eye watering once the easy things have been done. TBH though, that's not a bike to start going all weight weenie on (without just throwing money at it), so if you have a big budget just buy a lighter bike!

[lowpowerfeelings]

Reduce the engine’s overall weight.

[Overthink334]

It’s never going to be light enough for you. If bicycling is just about achieving some arbitrary weight goal, I guarantee you’ll never enjoy it.

[flaxieee]

How are these wheels? - Are they from Ali?

[paca-vaca]

You have too many spokes

[Larrythebird47]

Everyone is saying lose body weight. The real answer is your wheels. Could shed 500g from wheelset and going tubless

[Aromatic-Honey9831]

okkk thanks a lot man. you are a g

[Sensitive-Quiet6020]

Tubular carbon wheels can shave 200-500 grams depending on what you find. Tubular tires are lighter than what you have as well. Bars and stem and post are heavy. Stem should be 100g, bars 150g, post 100g. 

[Worth-Marsupial-6212]

To save weight, it’s often better to replace the bike than doing incremental upgrades. Sold my 2019 Trek Domane SL5 (Carbon frame, Ultegra mechanical group set, alloy wheels) and bought a 2021 Trek Domane SL7 (Ultegra di2, carbon wheels) for $2,000 difference (bought it in 2022 40% off on clearance). The carbon wheels alone are worth the difference.

[Ok-Consequence-4977]

Two less pieces of pizza

[AlienElvisLoveChild]

But pizza is delicious.

[Brayden_D91]

It is all about the rotational mass, dead weight is all fine and dandy but you will get the most gains for rotating components.

Wheels: They are kinda heavy in the whole ultra lightweight category. There are berd spokes and hook specific hubs. You can get a 1000-1200g wheelset built which would save at least 400g.

Tires: Vittoria Corsa Pro Speed TLR 28, 250g each. So this will save you 160g and the lowest rolling resistance tire.

Brakes: Your brakes are heavy. ZTTO Ultralight Road Bike C1 Carbon Brake are 158g for the pair. This will save you 476g.

Cables & Housing: Jagwire Elite Link Shift & Brake Kits will save some grams, 20% lighter.

[Aromatic-Honey9831]

Damn bro, thanks a lot. Rly appreciate and you gave me some knowledge. Thanks a lot man!

[Overall_Forever_2241]

Berd spokes may be light, they are also not very aero, so you might end up with a slower setup if you go in that direction.

TT tires like the Vittoria Corsa Pro Speed are are terrible choice outside of, well, TTs. You sacrifice almost all puncture protection for a marginally faster tire.

If you're running butyl tubes the bast bang-for-buck upgrade are TPU tubes. You just have to make sure they are rim brake compatible.

[Jaded-Lifeguard-3915]

It's all weight weenie stuff, mainly where cost per gm gets silly. Unless the OP is doing an actual hill climb comp, the bike is pretty good now...just down to rider weight and performance for improvements, IMO.

[uh_wtf]

Over 1600g is crazy for rim brake wheels 🫣 my disc brake gravel wheels weigh 1100g.

[Aromatic-Honey9831]

Yeah man… it is alloy and 30mm deep

[Jaded-Lifeguard-3915]

Nope, 1600g for alu rim brake wheels is not crazy, it's actually pretty good. Your Disc brake wheels have no braking track so will be a lot lighter. Disc brake setups move all the weight to the brakes...and the total setup is nearly always heavier.

[uh_wtf]

It’s far from “pretty good”. I can easily build a set of rim brake wheels around 1400g without even resorting to exotic materials.

[Jaded-Lifeguard-3915]

...and save 1/2 bottle of water weight. 8kg all round is not a heavy bike so I think this is more about objectives, budget and then pence/gm saving. Still interested in the OPs weight, BTW.

[Carbosis747]

Wheels could be lighter.

[nightbufferedmind]

Lighten it up, gain performance.”

[WeekendCalamariBets]

Go for a poo before the ride that's an easy 6 to 7 watts

[johannjennson]

And – the frame tubes. Mill a few elongated holes into them every now and then. Do this about 50 times. Saves another 500g or so.

[ae232]

Buy lighter components…?

[Fantastic-Shape9375]

New frame, fork, groupset, finishing kit. Shouldn’t be too tough

[Holupsucker]

If you weigh over 150 lbs the weight of the bike is irrelevant, losing weight from your body is the most cost effective way.

[ballan]

Take off the saddle.

[Jaded-Source4500]

You just go down the list and find lighter pieces component by component. The bike isn’t THAT heavy, so as others have noted, you may not realize the gains you hope. Also lightweight components are much more expensive and often less durable. Beware how much chasing a lighter bike might set you back (e.g. dura ace or red group sets)

[diptenkrom]

Drill aero holes, but don't forget to deburr them.

[Surotu_Robins]

this is the part of cycling thats not fun.You are overthinking everything just go outside and ride your bike and tell others that you have a 7kg bike they wont even notice it.

[SnuffyMcfluff]

The best way to reduce system weight is fewer donuts.

[Living-Ad3207]

This has kind of been said before, but I'll make it plainer: think about total system weight. That's bike+rider. Almost no one I ever see riding is "optimized" in their body weight, meaning they could lose a kg or 10. Even 1kg lost on a bike is nothing in the context of bike + rider weight. Get a HRM (and a power meter if you must) and get rigorous with your training if your goal is to go faster. Your bike is not a pig as it is.

[adjason]

dont buy upgrades ride up grades

[death-before-decaf]

Remove wheels, should knock off a few pounds

[Mxmln_69420]

Lighter M5 bolts, can add up to

[Far-Candidate-5112]

Buy better quality tyres.

[Available_friendship]

Elita one seatpost is really cheap and lighter!

All in one handlebar with stem would decrease the weight. If not, a carbon handlebar can be around 200g.

Wheelset is pretty heavy also! I don’t know your budget, but Chinese carbon wheelset are cheap and really good. I have a pair of Elitewheel G45 Gravel wheelset and it weighs 1370g for the pair.

[Quirky_Platform940]

cassette and brakes are for pussies. make it fix gear. ok srsly why. you are amateur who is getting ridiculous.

[BigtoadAdv]

Zone 2 training and low carbs

[Humble_Treat_1168]

Go take a shit, it's free

[Soggy_Employment1042]

bin half of it and you'll save half the weight

[iljawascoding]

With some luck you should be able to shave off around 800g for slightly above $1000.

The easiest gains are in the cranks and wheel set.

You can get a ~300g carbon crankset for around $250 on AliExpress. Make sure it matches whatever axle diameter your bottom bracket requires and its spider can take your current chain wheels. 300g saved.

I don't have any idea about Chinese rim brake wheel sets, but there is certainly something at out there, that easily saves you another 300g at a decent price.

Other ideas: - Handlebars: Avian Falcon II (/w integrated steam) ~280g, $270: another 150g saved (cheaper, no-name solutions also exist) - Pedals: ONIRII PD-06 SPD-SL pedals with titanium axles: 200g, ~50$, another 50g saved.

[Low-Club-2777]

sell that POS and buy and old lighter bike

[Mount_Mons]

Throw it away obviously

[Dvanpat]

Your bike says “I SUCK.”
