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?

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.

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.

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.

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

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.

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.

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

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.

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?

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?
