WOW! I got these at Royal Board shop in calgary for 20 bucks!
THEY GRIP, THEY SLIP, THEY CRAZY AWESOME!
nuff said.

I have nothing to say, they're just the best!!!

$35 at Switchbacklongboards.com, hopefully the price stays that low. Best slide wheels I've used to date. Very smooth grip-slip transition, super buttery slide, very controllable and predictable. Never had these slip out or grip up unexpectedly on me. Mold release is sticky and fairly choppy (to be expected), but once that's worn, they're the smoothest sliding wheels I've ever used. 140lbs ish, taken them out to 2 or 3 2hour+ sessions, mine are worn to ~66mm. No flatspots even after holding out a ~20ft shutdown slide at 90*. Very impressed by their wear patterns so far, and their slide characteristics. I'll definitely be buying more.

These. Wheels. ROCK! I picked up a set for my Clutch Lambchop and haven't been disappointed yet. Definitely my favorite freeride wheels I've ridden so far, and they're definitely worth it for the price.

Price: These things go for $39.95 on longboardskater.com, the only US online retailer for these wheels. These are the least expensive out of most freeride wheels on the market today that I could find (prices based on those advertised on longboardskater.com), such as Orangatang Freerides (up to $54, size dependent), Retro Freerides ($44.95), Pink Powerballs ($41.95), Abec 11 Classic Formula Freerides (up to $47, size dependent), EW Floaters (up to $49.95, size dependent), EW Road Rages, Smokers, and Obombers ($42.95, $44.95, and $48.95), and Venom Sidewinders ($40.95), to name a few. Needless to say, the price is competitive, and you are certainly getting a lot of bang for your buck.

Performance: As I've said before, my favorite freeride wheels I've ever ridden. They're sideset with a radiused outer lip, and come slightly "deconed" to allow for those extra few slides. I have never ridden a Krypto before, but I've heard the Cult Classic uses the same general Krypto shape with a few improvements.
The mysothane formula is a great formula for freeride. These wheels have a very predictable release and hookup, and once they're released, they slide like butter. Standup slides can be easily held out, and when you release the wheels for a big coleman or layback, you feel like you're positively gliding. Essentially, the slide on these wheels is genius.
They're pretty fast, definitely far faster than the urethane in Otang Freerides, but they don't feel as fast as my Lemon Zigzags. I have slid out a couple times on these, for instance, I didn't suck a frontside speedcheck all the way in when I was skating a narrow city road, and had to cut hard toeside to stay away from the curb; when I turned, my back wheels slipped out and I ended with a glorious superman, but that is going to happen with most dedicated freeride wheels.

Color/Style: This has never been a key piece of criteria for me when choosing wheels, but they're good looking nonetheless. The graphic stays on fairly well, certainly better than a zigzag or bigzig, and they're available in yellow thane with a pink graphic and core, and pink thane with a yellow graphic and core. The difference is purely cosmetic as far as I gather, as my friend's pink classics slide similar to my yellows.

Quality: I weigh about 140 lbs, and I'd say I've put close to 24 hours or so on these wheels, mostly freeriding and heelside predrifts from the local hills. They seem to be wearing pretty evenly, the outer lip's at about 68mm now and the inner lip looks to be a millimeter or 2 less. I haven't rotated them yet, and if they continue to stay at about this level of the coning, I don't expect that I'll need to flip them throughout their wear. I'm getting good impressions about their durability in the couple weeks I've owned them, and I've heard that they wear really nicely, so I have high hopes!

In summary, I would definitely recommend these wheels to both a serious freerider and someone just learning the ropes. Very easy to slide, and the slide is something more pleasant than most other wheels I've ridden. They're relatively fast, but I would by no means downhill on them due to their lack of grip, despite how pleasant their slide/drift is. They are very easy on the wallet, and are worth every penny unlike other wheels that I have owned.

Hope this review helps some to those of you on the fence! Now get up from your computer and go slashin' with some cult classics!
