How much does your gravel bike weigh? (why are they so heavy?)

[fa63]

On a separate note, I really like the Aspero, but struggle to understand the longer top tube versus the R5/R3 (at least in size 54).

The trend in gravel frames is towards a longer top tube combined with a shorter stem. I imagine that is why Cervelo chose to go that route as well.

Bingo. It's supposed to aid in handling for more technical sections.

So confirms I have underestimated the difference in tyre weight.

More progressive gravel bikes are supposed to be used with a shorter stem, just like modern mountain bikes.

Mmhh ...understood. It is a bit of trend with BMC adopting a similar approach.
I guess looking at frame numbers in isolation can be misleading. Comparing with the R Series, stack is the same and reach is 1 cm shorter for R series. So that would require a 2 cm shorter stem to be closer with the Aspero.

I typically like my gravel bike to be ~ 1cm higher and closer. I guess this is something different to try.

and it helps with front center when you have larger diameter tires (toe overlap)

Longer tt with a shorter stem doesnt allow you to get a long stem and start putting weight out in front of the front wheel also.

Why would you want to put weight in front of the front wheel?

You dont want to, thats why they make the top tube long. I was going to run a medium frame and a 140stem, but my fitter told me not to since that 3cm would put me in front of the axle. By preventing this, the bike should handle better on rough down hills.

My built is a Chinese frame (1100gr), Fork (400gr). Ultegra Di2 2x (48-34) and a assortment of very "normal" components ... some chinese carbon parts, magnesium rails saddle, etc. Total is 8.1kg with XTR pedals and "gravel" wheelset (Stan's Crest , Maxxis Rambler, 11-34 Ultegra cassette).
Obviously it is "easy" to cut down at least 600-700 grams using a road setup (carbon wheels -100-150grams, tyres -2 x 250gr , cassette -100gr).
So I also agree that 7.5kg on road setup should be pretty reasonable to achieve and it is basically 1kg more that what you would get for a lightweight rim brake bike on tubolars..(without fancy parts...)
For a carbon frames bike, I struggle to accept any bike over 8.5kg... it really mean to have very heavy wheelset and frame more on MTB side than gravel/CX side..

If I run through the numbers on my current build (waiting for frame, fork and handlebar) I guess it will be hard to go well below9kg for a size 60ish bike.
Using a GRX 1x build (2743gr) with XT pedals (340gr) and rotors (XT800 230gr) with a GR1600 wheelset (1816gr) and decent gravel tyres with 80ml sealant (vredestein aventura 44mm+orange endurance = 868+160gr) you're looking at 6157gr already.
Estimate for handelbar 260, seatpost 180, frame 1450 (painted 696 size 61) and fork (550) (fork and frame are estimates!) equals ~8.6 kg.
Then you still have small parts like Saddle (215gr), clamp (20gr), headset (105gr), expander (13gr), handlebar tape (50 Gr), BB (78gr), garmin mount (25gr), throug-axles (68gr) Nothing major but they do add around 500gr.

I know major weight-saving can be found in the wheels but other than that I wonder where (and obviously the frame and fork, as soon as they are in i'll weigh ) .

The secret to building light bikes it's to take off little bits everywhere.
Nothing listed is lightweight but it will probably ride really well. They're nice frames.

[onemanpeloton]

My boone weighs 8.5kg. Thats with a carbon seatpost topper, 1550g handbuilt wheels, panaracer gravelkings 32mm, force axs 1x and xt pedals Would take a fairly serious investment to reduce the weight much more

Keep on mind that for people like me and you (sizes 60ish) it will be impossible to compare the bike weights...it is funny when I read about light bycicles on size 49...ridden by people 1,55 cms tall weighing 50 kgs....

According to my source at Canyon weight difference between sizes is about 50g for Carbon, so how much is that between the smallest and largest size? 300g or so? I guess the only other component where size makes some difference is the bars, assuming that bigger bikes tend to have wider bars. Cranks should be almost negligible I think.

I dare you to find a lighter expander
Just can't wait to start building!
