Up through the BD C4s, the solid shaft Friends were still the lightest.
(Might seem strange, but the aluminum solid shaft is lighter than the steel cable shaft).
I haven't weighed the BD Ultralight Camalots, but I've heard they finally are lighter than Friends.

no one's mentioned the DMM cams? I'd bet they're in the running

Light skinny rope makes a huge difference high on a pitch.

For easy alpine climbing where the rope is there mostly for head gear and for the decent we use a single half rope.

Mammut Serenity gets you a 60m rated as a single rope for only 6.75lbs.

Any others better than that, rated as a single rope?

Beal makes an 8.5mm that's rated as a single at 48g/m. Works out to 6.3lb for 60m.

we used 7.8mm 70m for stuff that required longer raps and 8.8mm sterling marathon for 60m . neither rated for use as a single but thankfully I don't drink the cool aid so I am able to make reasonable decisions based on experience.

I knew there was a reason I haven't relegated my solid-shaft Friends to the museum bin, yet! (Paul Souza probably believes that my entire rack belongs in a museum, but that's a different story).

Old rack. BD ovals, 62 gms per
Newer rack. Petzl Spirits, 39 gms per
Latest rack. Petzl Ange, 34 gms per

So light enough for me to really notice.

But not while I'm actually climbing. Where I notice the weight difference is on the long uphill approaches. During aerobic work. That's why I love my new 8.7 mm single 60 meter rope.

All weight in ounces.




Slings similar on the last 3..
Negligible in weight.

And surprisingly by comparison..


Couldn't find #9 Hex..


Time to check the smaller cams..😬

Current #2 Camalot 155 g / 5.47oz size 2.55"
Ultralight #2 Camalot 126 g / 4.44 oz size 2.55"
Current #8 Hexentric 93 g / 3.28 oz size 2.51" (widest passive wedge)
Current #11 Hexentric 170 g / 6 oz size 2.56" (widest passive cam)

There may be an argument for the lightest still being the hexes if you're looking at blocky rock or rock with variable cracks that is very amenable to passive wedge placements. The versatility of cam placements through their whole range makes an argument for them being lighter in less broken rock and rock with more uniform crack size.

Up through the BD C4s, the solid shaft Friends were still the lightest.

I live with a guy (in his early 30s no less) who climbs with the solid shaft friends for exactly this reason. I didn't believe him until he stuck one in my hand. It really is counterintuitive.



The Tech Friend is made using more steel than the Jardine Friend. Steel is much more dense than aluminum.

The steel cable stem of the Tech Friend is thicker than it needs to be because the flexible cable they use needs to be fat enough that it doesn't buckle when pulling the trigger bar. That cable stem could be about half the diameter (one fourth the weight) and still be strong enough. A different cable, like a 1x19, would be stiff enough to resist the trigger pull.

So thank you from me too! I've never retired the original 'sticks' I have three pre US release with Brit. Made crude machine nuts that sprout sharp points. I keep an eye one them.

Re: Serenity ropes. I have a 70m. Rope that by my calculations of 51 grams/meter should weigh 7.8 pounds but on my scale actually weighs 8.5 pounds. Still a light rope and I like it. Especially at the end of a 70 meter pitch. Just not quite as light as advertised.

they should really switch rope specifications to weight per meter, as opposed to diameter-- the diameter changes dramatically with use, and people only really care about the weight anyway...

By the way, here is the rack beta for the Rupal Face, Nanga Parbat, Pakistan:
