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

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

Seems like most of them are really heavy. Even $6000 bikes like a santa cruz stigmata weigh 20+lb with pedals. How much do your guys' (and gals') bikes weigh?

I'm currently building a Hakka and hoping it will be in road bike weight range when finished. I would have liked a titanium frame but it seems like they all build up super heavy. Probably shouldn't even talk about steel frames.
Trek boone rsl with sram red mech/hydro and light bike 45mm is 7.71 with 28mm conti 4season is 7.71kg, size 58cm

Trek checkpoint sl7 is right at 9kg with 1x stram force axs and light bike 45mm with 38mm spec saw tooth.

Wow you guys have some really light ones.
I think the WW forum does not give a good idea of the weight of an average gravel bike. The granfondo magazine, issue 016 compares 13 gravel bikes and the calculated average weight of those bikes is 8,76 kgs.

Interesting. I guess they just have beefier parts than road bikes in general, and then there's the tires.

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.
I'm about to build up my Revolt.

Would be curious to see a photo of it or others?

Re: the Giant seat clamp, I'm surprised they don't use injection moulded carbon. It'd be much lighter and would be far less likely to damage the seat tube or seat post.

Not sure Darimo seatpost would be where I'd put my money. Stock one on my frameset was sub 150g, and cutting excess could probably drop it to 125g in my case. But maybe you had the older heavier seatpost design.
So there are 3 kinds of D-fuse seatpost Giant revolt are using, according to GIANT Japan:

D-FUSE COMPOSITE SEATPOST ~ 285g/350mm (the stock one from 2020 Revolt ADV 0)
D-FUSE SL COMPOSITE SEATPOST ~ 205g/350mm
D-FUSE SLR COMPOSITE SEATPOST ~198g/395mm

I assume you are using the SLR, it will be impressive if it could reach under 150g. My stock seatpost weighs near 285g, so I swap DARIMO customized seatpost which weighs only 100g/350mm.

For the entire seatpost system, I think GIANT is just giving too many things that are unnecessary, no matter the seatpost clamp for Revolt or the ISP seatpost cap for TCR ADVSL. Maybe they are always preserving something to upgrade for the next model. :x

Right. Disc brakes. Overbuilt fork. Wide rims. Fat tires. 2 bolt pedals. Chunky saddle. It all adds up, though 1x helps a little.

My chinesium gravel was 7.8ish with GK slicks 40mm. I did some upgrades to it since I last weight it, and now during winter it is always muddy or wet so cant be bothered to weight it again :)

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.
Drat, can't really compare because of size.. but my 52 alloy Jari with Apex-1 and some light-ish 27.5 alloy/novatec wheels, alloy everything else and m520 pedals comes to 9.4kg.

Post a photo when your new wheels come in!

I think one problem is that you don’t see a lot of 8-10k+ gravel bikes offered by manufacturers, unlike the road.

Using the Aspero as an example, the most expensive one comes with Force AXS, and a bunch of mid- or low-level components. Like, wheels with DT 370 hubs, Easton EC70 bars, etc. Meh.

That’s why we started with the Apex 1 build for my wife. Good enough to get started on, and we can replace parts over time when we find great deals. The upper level models just don’t make sense to me, for what they cost.

interesting! I would have thought the extra weight of my 61cm frame should be more than made up for by carbon vs alloy...and from what you're saying most of my components should be lighter as well...sometimes I think someone in the Fuji factory accidentally left a lead weight somewhere inside the frame ;) Or it's just the wheels...I have not weighed them without rotors and tires etc...but I estimate them to be almost 2.1kg...

Such variations in weight wow. My 2020 Norco Search XR C3 saw a few upgrades, got rid of the dropper for a lighter alloy post (~260g), using Bontrager Pro 3V wheels, 42mm WTB Resolute tires, 200g saddle, weightweenie Zeray pedals (I think 270g a pair), MT800 rotors.. still comes out at almost 9.5kg in size 58! Includes cages, Garmin mount, pedals, etc. but still.

Here's stock bike before the upgrades: https://www.norco.com/bike-archives/2020/search-xr-c3/

My Factor LS is 7.0kg with 35mm G-One speed tires on G23 wheels.

edit: this includes pedal, Spurcycle bell, hydro GRX sub brake levers and a Lupine SL A lamphead mounted in front of headtube.
I could get down there myself (parlee z0-xd w/ Enve 4.5AR and BonJons)... but adding the suspension stem and electronic dropper all those hopes and dream flew out the window.
The sub brake levers are nice on a gravel bike especially on rough stuff. I could eliminate that and save several grams or add a dropper post which will add quite a bit more. But since I use this for 80/20 pavement/gravel, it works well like it is. Even with the G23 wheels and 35mm G-One speed tires, it fairly fast on group road rides. Not having to worry about cracks or debris on the road makes it ideal to ride in late fall going into winter.

My BMC CX01 has ranged from 7.2-7.5.

A newer XCR steel canti based is 7.8 kg. On this one the cranks are 50/34 Red. In hindsight, I should have put 48/32, this would allow to swap the cassette from Ultegra 11-34 to Red 11-32, dropping ~150 grams and keeping the 1:1 ratio (and a less spread cassette).

I guess gravel bikes are heavier because of the frame (+200 grams?), fork (+100?), tyres (250?) and wheels (200?). Further, gravel bikes are less likely to be mounted with lighter group set.

So a light disc bike (7.5 kg?) equates to a light gravel at 8.25 kg.

Tires are a lot more than a 250g penalty most of the time. Decent road tires are 250g each. Most larger gravel tires 37-40c run 460-520g each.

That 500g is huge.

That is a good point; lots of variance in what we call gravel tyres.

I typically run on 33/36 mm and I rather slicks.

38 mm GK Compass are around the 300 grams mark.

The BMC weighs 7.5 with heavy 36 mm tubulars (I think they are over 400 grams) and 7.2 with the 38 mm GK in tubeless set up (and a couple other heavier components).

But yes, I can see most people on 400 or more gram tyres.

I just compared the weight of my Aspero 2020 with my Cervelo R3 disc 2018: frame & fork 1700 g vs 1330 g, tyres 990 g vs 450 g, wheels 1530 g vs 1470 g.

So confirms I have underestimated the difference in tyre weight.

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).
