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

Especially for light weight issues concerning cyclocross / touring bikes & parts.

To be honest I find most light weight expanders to be fairly crap. I stick with the specialized ones which work really well.
Not the lightest but that's my preference.

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 :)) .
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.... :D
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 think you are right; and actually 300 gram gap seems to much. Imagine a SuperSix at 700 grams and another at 1kg?

Wider bars - 20/30 grams? Seat post not cut- another 20/30?

A seperate but related topic is weightweenie parts not being suitable for taller individuals, likely to be heavier (you know better than I, you re tall).

Agree, although this carbon-ti works really well on my other bike. i've got a boat-anchor style 5cm deda ready if i don't feel this will do the trick ;)

My saffron (XCR stainless with carbon isp), steel custom topper, enve aero cotpit, etap AXS red, enve cages, DA pedals, Sworks power saddle, garmin mount and custom paint, Columbus futura forks weighs 9kg wether with Roval CLx 50s and GP5000 32s or with Beast 40mm gravel wheels on dt180 hubs and Terra speed 35mm tyres... and is the equivalent to a size 58.. but it's not a small frame, it's steel and it's painted
Perdita- Burls Ti - 8kg
Aurelia- Saffron Stainless/Carbon - 9kg
Bertha - Trek Speedconcept
Verity - Sturdy Ti/Carbon Aero (incoming)
Serenity- Sturdy Ti (incoming)
Allegra - Sturdy Steel Lugged (incoming)
Jolene - Aluminium Crit Bike (being reborn)

yeah, I guess typically it's a little less than that, depends on how many sizes there are and for very light frames it should be proportionally less difference...

My 2021 S-Works Crux weighs 15.75 lbs (7.15 kg) with Red/XX1 AXS, an E.13 Helix 9-50 cassette, Nextie/240 wheels, 35c Hutchinsons, 140mm Ashima rotors, E.13 XCXr cranks, Whisky No.9 12F bars, Tune Geiles Teil 4.0 stem, Specialized Alpinist post, and an S-Works Romin Evo. That weight also includes two Enve bottle cages, a Wahoo speed sensor, Wahoo cadence sensor, and a Wahoo Elmnt Bolt head unit/mount.

My previous carbon gravel bike, a Scott Addict Gravel 20, was 14.75 lbs (6.7 kg) with Force 1, EC90s, and a 3T 9-32 cassette. :noidea:

Rode the same bit on Saturday and it was a bit different, average temperature was 4°C, didn't stop for photos :)

My Giant Revolt is about 7.3kg (7.1 kg w/o pedals), I used darimo, extralite, farsports to get my weight down.

I would say the current UT R8050 is very heavy, one pair of shifter's weight over 500 grams, the 11-34 cassette weighs over 300 grams, which both are certainly terrible. One thing more terrible is that I never use 30/34 ring, for me 11-28 is enough.
The praxis crankset weighs over 600 grams, and the shifting is not satisfying plus some awful noisy sounds from BB.
The seatpost clamp is also such a failure, it's heavy, difficult to adjust, and not replaceable.

I plan to use DA 9270 to replace UT 8050, except for the crankset. (estimated saving over 350g replacing shifting parts and cassette)
For the crankset, I am thinking either thm+extralite or incolor's skypivot. (estimated saving nearly 200g)

My long term plan is to get my gravel bike under 6.8kg with pedals.
Do you know the Frame/Fork/D seatpost weight of your Revolt frame?

I have a Fuji Jari Carbon in size 61 (claimed frame weight under 1000g) which was about 10.3kg new with SRAM Rival 1x, inhouse components, FSA Omega crank, heavy wheels and 43mm (tubed) Gravelking SK, XT pedals

I have since gone tubeless and swapped the bar and stem for parts I still had (Easton EA90 stem, EC70 42cm bars) and the FSA cranks for a 2nd hand SRAM Red. The Fuji seatpost was replaced by 130g Elita One and I replaced about 30 or so unused bolts with plastic screws.

I am down to about 9.4kg now but have a pair of Farsports gravel wheels on the way which should get me down to 8.7 at least. But that's where it will realistically stop for me at this point. I don't really want to change the Rival components as they work pretty flawlessly, but whenever they need replacing I'll go for something lighter. I could also save quite some weight on the tires but I just like the Gravelkings in 43 too much. 8.7 isn't too bad for a bike that can pretty much go anywhere, though...and it wasn't the most expensive either. I paid just over 2000 Euros in an end of season sale plus the new components and wheels of course...so still under 3000 with quite a bit of weight optimization potential left ;)
I"ve now finally received my Farsports Gravel wheels (1398g the pair, 36mm deep, 30 wide, hookless, Novatec hubs) which has made quite a massive difference in terms of weight. I am down to 8.62kg now including bottle cages, pedals, garmin mount and a light mount. I guess that's it for now...anything else will only be changed for something lighter when broken or worn ;)
