I'm thinking about taking my link cams out this winter, in the rare instance that I would need to put in some rock pro on a mixed pitch. Anyone have any experience with Link Cams in the fucking freezing conditions? Are they more prone to freeze up with a little bit of moisture due to all the moving parts, or does their large range make up for the potential downfalls.

I've definitely gotten fist jams between ice columns. I'm not sure I'd place a cam there though.
Or more seriously, the more stuff to freeze, the worse it could fail on you. You're probably fine in dry conditions but for wet days and ice hanging off your rack, I'd go all passive with a handful of pitons too.

I'd agree.
You could test them by getting one wet and throwing it in the freezer.
If you do use them maybe it would be a good idea to use a lube that displaces water?

Like a thick grease? White lithium or similar?

Yeah I'm not thinking of placing it between ice columns. That just sounds like a quick ticket to a shattered spine.
Pins are out for now unless I get rid of teh littul gurly-mahn hammer that came on my reactors or get a backup tool with a hammer.

Depending on the area and conditions, pins are often required gear. You could just carry a pin hammer too.

I use Triflow lubricant with teflon to keep my bike running smooth in the winter. A little goes a long way. Make sure to wipe off excess so not to attract dirt and grunge.

I think you can still get mansized replacment hammers off the BD website.

I use cams of all sorts on winter climbs...just keep em lubed, keep em clean, and watch where you place em.
But as for what it is that I'm most concerned about in cam placements, the actual unit itself freezing is less of a concern than the basic mechanical/frictional limitations of cam units in general, especially on winter climbs.
To wit, foo; Cams in general need to be used cautiously in the winter environment. The friction coefficient of a wet crack or dirty alpine crack is less than a dry clean one, which can and does lead to cam placement failure. And any ice in the crack....you can pretty much forget about that placement holding any kind of fall.
So the previous poster who suggests pins and passive placements gives good advice.
You can still use cams, but many placements will be better to use passive pro or pins. Use yer Noggin, and Get yer hammer out, cause mixed season is here.
PS: real men can pound a 3/4" angle or a Lost arrow in solidly with their forehead.

I could drill in granite with the hammer on my tools. What the hell is up with these cute little hammers anyway?
I mean, I want a hammer I can hit shit with or I don't want a hammer.

Doc, leave the Slinky at home for mixed. Depending on the conditions and type of route I'm going on here's what I use as a "mixed" rack in the rockies.
For routes I don't expect to need pro > 1.5"
1/2 set nuts
Tricams (typically modified pink, old, pink, new pink, red, brown, sometimes blue)
2KB's
2LA's (typically one of them being soft iron)
2 Angles (#1, #2) - Occasionally a short shallow angle
1-2 DMM Bulldog/BD Spectre (typically only one. I like the DMM better)
4 to 12 screws depending on length of Ice pitches
If I expect a need for pro >1.5" I'll supliment that with a mixture of Hexes and Cams, maybe a couple larger angles too.

Thanks for the insight.
I'm going to freeze 'slinky' overnight and see what happens.
Report to follow.

The slinky is in the freezer.
I'm on my way to tanked.
Someone remind me to remove my cam from the freeze either tomorrow or before tax day.

I wonder if it has frozen yet.
Time to violate experimental protocol.

Non peer reviewed consensus....
Fucking useless. A splash of water and freezing temps rendered the cam unable to form to any shape. maybe a low temp lube would help, but otherwise they just become a chunk of frozen aluminum.

I would like to thank the experimental sponsors, Omega pacific for letting me buy their wonderful cams, Carlsberg beer for letting me buy their mediocre beer, and water, for becoming a solid at around 32 degrees for the results of this experiment.

For your next experiment, have a couple more beers and see how the Link Cam fares in the microwave!

Maybe the next experiment will be how my #5 camalot fares in your rectum. Fuck off and die.

Yeah the brochure for tricams actually advertises their use in icy cracks or a crack with one side ice and the other rock. Crazy. You could get one of those medieval looking honkers for large pro.

p.s. if i wanted to grab say 5 pitons for winter alpine stuff/in the extremely odd chance i need one or two on say an A3 cannon route, what should i grab. and i don't mean 2 LA's, 2 KB's, 2 angles, etc. i mean what specific sizes are good, cause there are like 7 of each, and i don't have a feel for the numbers versus the actual size.
follow up, and i'm sure it's in another thread, but when is each type best, i.e. LA's horizontals?, etc.
thanks!
