My new 2024 Domane SL 5 is .95# heavier than it should be.

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

I know you have tubeless tires, but to confirm, the bike is setup tubeless and doesn't have tubes installed? Are there any tools included/not included in the in-frame compartment?
Yeah, that also immediately stood out for me. Then, thinking about the 'rider', it might be an adaption for the possible majority of audience for 50 & below - female?

The listed weight for the bike is without the pedals. And it's just a there about weight and not a precise weight.

Perhaps for bikes that come from the factory with pedals that are included in the specifications for the bike, then the weight might include them. But I've not seen spec's for a Domane that included pedals.

If you care seriously about a lightweight bike, a bike listed at 19lbs would be heavy and you would build your own and make it light.
Think of it this way perhaps with a slightly different scenario.

A Domane SLR frameset only supposedly saves 1/2 lb over the OP's Domane SL frameset. The premium for the SLR frameset is $1700 over the cost of the SL. If he had instead purchased an SLR bike and it actually weighed 1/2lb over what an SL bike would have supposedly weighed, you might be a bit upset about not understanding what your $1700 actually bought you.

If you’re concerned, send an email to the Trek CEO. He is very responsive.

Especially given his smaller sized frame/bike. All the components are a know quantity, quality frame should also not have much deviation, so a lb+ is a lot.

My post was mainly to 'confirm' that what he found was probably 'reality', not a major anomaly in just his bike.

In my case, I bought the bike fully knowing what I was getting, and not expecting more. Also fully expecting to be making some changes. Having ridden 'THIS' bike before committing to purchase.
Not unhappy with the bikes I currently ride a lot. If I can make this new bike feel as 'nice' as those - great! AND fully intending to make changes, upgrades if that fits, to see what might have a significant effect on 'ride', and see if 'weight' also is part of the story. It's an experiment...
If I can bring it to level of my current road bikes, which are all 10 yrs old or older, then Great ! If not, I'll sell it for whatever it might go for... No issues, no problem.
It's not the money, I have a bunch of fun learning what this experiment might teach me.
If I had spent 4 times what this bike cost me, I'd have very, very high expectations, and hopefully, mostly have them met... My expected changes will cost about half again of the bike cost, which would still be considered a bargain compared to the price of a similarly fitted 'Off the Shelf' bike cost.
I think most knowing riders also know that 'weight' isn;t everything, but it is a 'thing'.... So for a bike with $3400 MSRP, one might expect it to be in the 'light' road bike category... 21+ lbs is not that, compared to the similar bike, 19ish lb, of 8-10 yrs ago which prolly sold for $2K-$2.2K.
SO, with this thread a lot of questions get asked, some answers might be found, some not.
And, it also addresses expectations, so met, some not even close.
So, if one has expectations to be able to get a 'light bike from TREK (and other bike makes?), well under 20 lbs, it might not be met by even a $5k bike... ?
For some this might be an important consideration.
Ride On
Yuri
and , yes, I prefer my 2014 Tarmac well over any of my old gaspipe, and many of the 'great' newer bikes I've had some opportune miles to log a few miles on...
Not a plug for Spec or Tarmac, it's just a bike I like a lot. But had the experiment be able to be done with an ORBEA, WILLIER, CERVELO or RIDLEY, instead of a TREK, I would have quickly jumped on that.
Yes the components are a known quantity but they are also manufactured and there is plenty of variations in manufacturing plus adding in unweighed pedals and unweighed tubeless set up and not knowing how Trek weighed their bike. Frequently they will weigh a pre-production sample missing certain parts to help get the weight down or they will have to replace a part during the production that has a different weight from the single bike they weighed.

Sure that is fair but nothing is scientific enough here to really know if anything is correct. Obviously if you are spending money and it turns out significantly heavier and you paid more that is frustrating but we don't know the full situation on any side.

The tubeless weight without sealant (which is probably what they quoted) is likely to be 200 gm lighter, at least.

Also, as noted above, the bike probably came with tubes in it.

Just to emphasize the point: if present in the tires, the tubes alone account for most or all of the difference.

If shipping that and other high-end Trek models with tubes in the tires is standard policy, Trek could have saved themselves some future grief by specifying that the weights are fairly accurate for the bikes when they're run tubeless but that they're supplied with tubes in place, to avoid problems with, e.g., sealant pooling at the bottom of the tires while the bikes are in storage.

That's my two cent. Lightweight and 19lbs don't go together. Trek and lightweight neither.

It is worth keeping this in perspective. A liter of water weighs about 2.2 lbs.

That is without bottles and cages.

I've never owned a bike lighter than 20 lbs.

I've never weighed less than 180 lbs in my adult life.

And I'll bet $10 that the OP doesn't race. Not that an extra pound would make a difference.

'Course, I get that he's upset that the promise is not reality. But that's usually how life works, right?

Maybe your pedals are heavier than you think? Did it have bottle cages attached? A computer mount? Maybe they added a lot of extra sealant? Difference in scale accuracy?

Could be many reasons, or simply Trek being optimistic in their advertised weight. Who knows.

Buy it. Ride it. Enjoy.
Nothing was added to the bike but the pedals and tire sealant. But I will deduct 57 grams from the 430 for the empty tool bag that was in the down tube from the factory.

While I understand that the importance of bike weight is somewhat overblown, bikes have definitely become porky - we're looking at 20-21lb as nothing unusual for a CF frame with decent bits - yikes
Are you sure there is a spring in the park scale? Electronic load cells these days are cheap and accurate.

Bodyweight also naturally varies by 2-4 lbs over the course of a day.

The advertised weight for most manufacturers is for 56cm framesets so you're right saying that your 50cm should weigh less. For instance, my 2024 SL8 Pro in size 58cm came up at 7.3kg on the LBS' park tool scale. Its advertised weight is 7.16kg (size 56cm). I don't mind the 140g difference given that it's a size bigger.

Are you 100% sure that your scale is accurate? Have you tested it with other items to which you know the exact weight?
It isn’t my scale. It is the bike shop’s scale. If it is reading heavy, I would think that it would be in their own interest to replace it.

I’m not pleased about the extra weight but I am not greatly worried about it either. That’s why I came here to ask the forum, is it typical or is it outside of the normal range?

And---just reconfirming---there were no tubes in the tires when you weighed the bike?

My guess is the shop's scale is accurate.

At some point the marketing becomes misrepresentation.

At a more extreme point, it becomes a form of consumer fraud.

Giant seems to be a bit more cautious in this regard:

Yes it is set up tubeless, by the bike shop. The only thing on the bike was the pedals, which I deducted from the weight. However, there was the empty Bontrager tool bag in the down tube that I forgot about. I weighed it today on my kitchen scale and it accounts for 57 grams (0.125 of the excess .95 pounds).

About the wider saddle I did notice that. It might be that they sell more 50’s and smaller to women than men (as also noted in this thread by cyclezen).

For perspective, Trek charges about $2k for every 1lb reduction you want off of their frame weights

I have no idea whether most bikes weigh near, more, or less than listed weights. No one really does, because none of us weight a dozen or two bikes in each frame size to know.

The weight saving aspect of this cost is poor value, but you generally get a higher quality build ie higher level groupset, nicer wheels etc. it’s not only about the weight.

I wasn't even considering the groupset and components; only looking at their frameset pricing.
