.....not purposely. I've skied my liberty double helix's less than 10 days and they are already starting to deform. damn bamboo cores...

has anybody else had an experience like this?
 
More than likely they came from the manufacturer like that, it would take a lot of aggressive skiing and much more damage than I see there to warp them that bad. If the company wont warranty, your local ski shop might be able to base grind some of that out.
 
is there actually a disadvantage about convex bases?concave bases are more likely to catch an edge but wouldn't convex bases be the shit for skiing? especially jibbing and powpow?
 
^ powder yes, but i think jibbing would be really wobbly and unstable and you would really have to try hard to get a grip on anything
 
i dunno, as mentioned earlier there are bataleon boards that aren't flat and normally you're always on an edge when approaching jumps...
and when you land your skis will be much more forgiving since the edges are less likely to hook...
or am i completely wrong?
 
on hardpack they're kinda funky. it would take some getting used to. they feel really dead when your you carve on the groomers. i haven't noticed a significant differnece in pow yet, but then again i don't know how long they have been like this. - i just noticed the problem yesterday.

i'm not sure if i did all the damage, but i can tell you that the skis are only bent in the tips and tails (both skis). underfoot they appear to be flat. i heard that liberty had problems with making their fatter skis torsionally stiff enough - i didn't think it would be this bad.
 
I have been thinking for a while now about how a pair of skis with convex bases in the tips and tail, while being normal throughout the rest of the ski, would ride. Seems like if you could find the right % of the ski to use, it would be fun as hell for butters and flatland ski tricks while still performing quite well on groomers. :P
 
most big companies send their skis out unfinished. like needing to be stone ground and waxed and structured. your liberty skis probably have sat around for at least 6 months waiting for you to buy them.

if you had bought some on3ps or something these guys actually spend time with your skis and make sure they are ready to shread when they show up at your door.
 
1. You're an idiot. Liberty is a TINY company. They only have 5 or 6 employees.

2. You're still an idiot. You think Rossi, Salomon, K2, et al, are shipping "unfinished" skis to Backcountry.com and REI? If a ski company sold a brand new $800 ski with a disclaimer that said, "You have to take these to your shop and pay $50 for a full tune before using them," NOBODY would buy the skis.
 
skis come usually ready to ride...except they're usually not completely wax saturated wich isn't a very big deal....
 
Might not want to go slanging insults like that. A lot of companies apparently do. Talk to the lucky shop tech that gets to tune Burton boards and ask them if they come from the factory flat.
 
think of a boat on land, it would roll over to its sides way to easily

that's what cars wheels are at the edge and at all four corner. stability

same will apply to the ski. without those tires on the car, you cannot make a turn because there is nothing to create the force to push you into your turn.

maybe in powder it would be cool, like a boat in water
 
yeah, but if you'd look at lets say the bataleon boards, they aren't flat either + usually you carve on an edge, so using your boat analogy; the boat would tilt to a side and remain stable, on an edge...
anyways, convex bases would be a pain in the ass to wax, scrape and stonegrind... so probably no go ....
 
Some of this years Fischer pow skiis are shaped like a boat hull at the front, it only extends about 15cm back on the ski but apparently it helps....
 
Burton uses convex bases on some of their kids snowboards to help noobs learn to roll from one edge to another.

they also use a similar tech in their adult boards where they roll up the base near the edges slightly in the tip and tail section which helps free up the 4 contact points on a snowboard and it helps adult noobs/park junkies in a similar fashion.

i wonder what some convex base action in the tip and tail of a ski would ride like (ex. 10-15% rocker AND convex base)?

 
yeah dude; making the rockered bases convex would probably be an advantage !2011-2012 rockered skis => boat hull ?
 
i know, but so far fischer is the only one with that concept rigt now, and i dont think its incorporated with any rocker, is it ?

 
sounds great; do you, by accident, have some pictures of the hull shaped ski?cause all i can find is a sketch from fisher and some meaningless topsheet graphics for the wateas....
 
There is a ridiculous amount of innovation that's been going into powder boards lately, I think this may be the next step to the ultimate powder surfboards. Basically:
Spoon nose convex base on tip + between 50 and 70cm of rocker + stiff on the tail, soft underfoot and on the nose = Ultimate Surf/Charging ski
 
i rode the skis today in some heavy pow and they slayed. so easy to turn. (not as easy as the arg's though, which i rode later in the day.) on the soft groomers at the bottom they performed well - real easy to roll from turn to turn. they were a bit squirrly if they weren't on edge though. i think i'm going to keep the skis a while longer before i think about a warranty.

ski companies should look into convex bases; i think it would make a super fun pow /soft groomer/ crud ski imo.
 
but you have to put that much more effort into it to get on edge, and hold the edge

and the fischer boat hull its really convex bases, i mean its really a boat hull kind of shape, and only has an effect in pow, and the rest of the bases are flat so its hardly the same
