What are bike manufacturers not doing that they could be? ‘Just make them lighterer!’ isn’t really helpful.
Im not an engineer. If I was I would be working on making them lighter rather than posting on here. Scott seem to know how to make frames lighter that I’m sure are as durable as anyone else’s
think bike manufacturers are learning more about the properties of carbon and how the different weaves and layups influence the characteristics of the frame – compliance, stiffness etc.
I would expect them to hire people who know this rather than use customers as their test team. I want to buy a bike designed by those who know what they are doing, not learning as they go

In terms of mountain bikes Scott always come up light on paper, can't say I've been convinced when I've picked them up but the calibration on my lifting isn't very good. Their road bikes do feel like they should be chained down in case they float away on a draft though.
IIRC giant's high end alloy frames are often lighter than the carbon equivalent in theirs and many others ranges.

It's not like it's a work experience kid running the process and discovering it didn't cure at that temperature. These are cutting edge research labs and the like improving things as they go.

Lolz.
The engineering of aluminium verses carbon would be an interesting article
My hunch would be that engineering a frame for the expected forces in use carbon would be lots lighter. My hunch is that you start adding carbon to cope with the forces that arise from crashes and impacts the weight advantage starts to decrease
My hunch would be that
By the time you put in a load of bearings and axles, make linkages that don't crumble or flex, put in BB inserts, headset cups and 1kg of coil shock there's surprisingly little weight to shave off the actual frame construction.
Regarding carbon engineering. Hope have close connections (ie the hope founders used to work there) with Rolls Royce in Barnoldswick. When they decided to make frames they got the RR aerospace carbon engineers in to show them how to do it. I don't think there is any guess work or trial and error going on here.

Top of the range Ransom is still over 30lbs, just. And £8500. The next one down is £6k and 32lbs.
Frame weight is 6lbs. Can’t find details on the 916, but given its burly build kit giving a total of 35lbs I wouldn’t imagine there’s a huge (noticeable out in the trail) difference in frame weight.
Something something system weight something 2-5% something.
Very nice. Do they do an eeb version 🙂

I used to work for Scott and I wouldn't give them the sweat from my balls if they were dying of dehydration.
But I am bothered about whether I get up it at all, and on a gbadgery techie climb at my limit 2kg is a huge amount and would frequently be the difference between success and walking.
I've was amazed at the stuff I've cleared uphill on my Nukeproof Mega 290. 29" Wheels, properly sorted geometry that means theres loads of rear wheel grip without the front lifting (but not so long that you can't change direction or lift the front when you need to). I'd say it's pretty damn rare that the weight of the bike is what makes you dab on a tech climb.
And an extra few kg on a bike isn't pleasant but it doesn't stop you putting it on your back for a hike-a-bike. I shouldered my Orbea Rise up the Fairfield Horseshoe last week.

Mm agreed. The two big bikes that I've had (Enduro and Occam) were far better up short climbs than any of my old light bikes, but after a few 10s of metres the additional weight kicks in and it ain't happening.

On the actual Horseshoe? How much of it were you able to ride? We did Grisedale Tarn - summit- western descent to Rydal and looking at the eastern ridge ascent nearly made me go and buy an Orbea Rise just for that 1 ride. It looked perfect for an eeb.
...but from what you're saying perhaps not. Was the HaB shortish bits?
Did the eeb make the difference on the amazing looking ascents?
Clockwise or anti?
Everyone moaning about weight - this is a £7k build... which sounds a lot these days but that would only get you an entry level carbon Santa cruz, spech or trek these days.
If you chuck £10k rrp at a build you’d easily get this down to 32lb with carbon wheels, carbon bits everywhere etc.
I’ve ridden a 33lb build of this and it feels anything but heavy picking up or on the trail.
I wouldn’t buy one - largely because I couldn’t ride a a non eMTB now to do it justice, but also because it is very fugly.
fugly

I'm really not clear what your point is here 🙂
That if you spend a frankly insane five figure sum you can get a not quite so heavy version?
Wow, that's just amaze... no it's not really anything.
It's means nothing. Ten grand is an insane amount of money.
I mean for ten grand you could chuck the frame in the bin and still get it down to 13kg.
Have we really got to the stage where the fact that 10 grand buys you a not so very heavy version of a bike is seen as amazeballs?
Can you point me to an off the shelf 13kg 170mm 29er enduro bike, for any price?
Closest I can find is a 13.5kg 160mm travel one (with flex pivots) for €9500, a Last Tarvo.

Agreed. It is better than not riding at all though.
