Strengths: Looks nice..
Weaknesses: The problem with Kooka cranks is that the company had been on the verge of folding since the word go.. I suspect it was to do with the bonnie 'hardcore' cross country cranks, which I split twice.. Both times just commuting on them.. They seem to hold up just fine to abuse, but you can't be a featherweight on them.. I eventually managed to trade in my later ones for a pair of downhill cranks and I loved them for a while, but they just seem to have developed a split from the bottom bracket about an inch towards the pedal.. I have also managed to pull a chunk of the crank arm off when I recieved a small impact on my chainring.. This tore one of the spider bolts out with a piece of the aluminium.. Never worthwhile at all.. I'm killing these solid machined pieces of aluminium on my 6 year old cannondale hardtail.. I realistically should be able to tear the bottom bracket shell off my cross country frame before I put a dint in these cranks, but there you go..
sucks arse in a big way.. I plan to stick them on my wall though.. They suck, but they're purty..
Bike Setup: Cannondale killer v 800, Dirt Jumper 2's set up for street..

Strengths: One of the most unique features to this crankset that no others offer is the ability to adjust your chainline. This allows this one crankset to be used on many, if not all, frames out there. I've used many crankset that, due to the frame design, would not allow proper chain alignment, thus not allowing you to access your entire cassette. And let's face it, when you only have one chainring up front, you need every single one of those little ba$tards in back! The other strength is its strength. See Bottom Line.
Weaknesses: None. Period. 'Nuff said.
Okay, listen up. I'm not gonna clown on any other crank manufacturers out there. There's good ones, there's bad ones, and then there's KOOKA. These guys are in their own category. Customer service is out of this world. But here's where I'm sold:
Long story made short: I was trying to take first in a DH race. I made the mistake of trying to bunny-hop from the top of a 7-foot drop-off and across the 8-foot rock garden that started at the bottom of the drop. Well folks, we all come up short some time. This was mine. I (240 pounds) landed squarely on the MRP chainguide on a rock the size of an office desk. The landing was absolutely brutal! But the crankset didn't budge! And to this day its still in absolutely perfect condition (no loss in alignment of any direction). It may be a little difficult finding these cranks in stock at a shop, but give KOOKA a call and they will hook you up for sure. Buy these cranks or ride without confidense, take your pick!
Strengths: Unbelievably stiff. Supposedly, no one has ever broken a Kooka dh crank arm.
Weaknesses: Fit and adjustment. I use an older set of Kooka Razor arms with a newer freeride spider. With the triple chain ring set up, there is sometimes rubbing of the inner chain bolts on the derailleur mount. This could be solved by running a wider bottom bracket. Moral of the story: Even if your old cranks ran fine, you may have to get a new BB for the Kookas. I have to say that, probably due to my own poor skills as a bike mechanic, the cranks creak.
A stiff crank. Be sure to use a stiff bottom bracket.
Weaknesses: I bought the dh setup. I ordered a compact spider and the rings sway. So far no reply from Kooka. Bottom line! Poor machining. I have to tighten the driveside after every ride. They creak. They would be great if my chain didn't rub my deraileur and cause chain derail.
It's stiff. I have to run a 115 mm XT bb cause there's no clearance for 113 raceface. This crank can take a beating. Other than it creaks, I constantly have to tighten the driveside. After a big drop or jump it gives a nice creak. These cranks are the razor DH. They have the old Kooka logo. Not sure if the new cranks are machined a little better but these suck!! I like the stiffness but hate the noises they make. If I didn't live in Wa state I think I might be able to get a little better cust. support. 4 chilis cause they're cheap, 1 chili cause they creak and cust service isn't all that.
Weaknesses: Will destroy Shimano BB's because they're so strong and stiff
Very, very strong and will last forever but just don't run a crappy BB or you'll get a nasty surpise. Shimano BBs don't last and when they snap they're really sharp. Don't just get good cranks; invest in a decent BB too. Unconditional lifetime guarantee.

Strengths: I have the free ride cranks, not the DH ones. They rule, they are Strong, Fatt and the best. So good and they have not broken yet, more than I can say for my bottom bracket. Unconditional life time guarantee. If you need cranks that will last, buys these. Remember kooka and forget about the rest. (No I do not work for kooka, I just believe in a good company which sell good parts that last.)
Weaknesses: There is none, they are kooka. Yes the little end of the crank arm does stick out so it will snag your pants. So put on your old school vans and pinch roll your pants.
Strengths: These are strong as hell!! They are stonger than your BO after a day of shuttling!! Bomb-proof!!
Weaknesses: Have to run longer BB than Race Face DH because crank arms are straight.
Bang for the buck, these can;t be beat! RF are lighter, but these are the stiffest cranks I have ever stepped my 215lbs of frame flexing force on to! Be prepared to get the NEXT larger BB to Accomodate your MRP. Revesible offset spider is nice, but buy OPEN MRP PLates to accomodate ltd. clearance of outer plate and arm!!

Strengths: They are sooooo stiff you will probabaly notice a hugh difference the first time youn ride them. They are also indestructable and and if you are a freak who can break, bend, or strip them they have an uncoditional lifetime warranty.
Weaknesses: Are you kidding?
Damn, these things are worth the money you will pay for them plus a whole lot more. They are cheaper than raceface and these will never bend or srip out. Race face North Shores are nice but too damn expensive do your self a favour and buy the last pair of cranks you will ever need. If you have ever bent, or broke cranks or you these are for you.

Strengths: hmmmm, they are the strongest and beefiest crank on the market. Unconditional lifetime warranty, last cranks you'll ever need to buy. Replacable spyder (can be changed from 5bolt standard to 4 bolt)
Weaknesses: shutup. U ask for strong cranks and that's what you get.
Sick of bending, breaking, and snapping your cranks? Well Kooka over engineers it's cranks so that there is no way to break em. Sure they're heavy, but you wanted strenghth! SO if your sick of breaking cranks hook yourself up with these, they might be overkill but they'll last. The bonus is they're cheaper than the competition.
Similar Products Used: POS cyclone and shimano cranks that don't last more than a month.
Bike Setup: '98 VPS1, Z1 droppoffs, Race Face steel taper lock BB, Mammoth Rims, etc etc.

Strengths: Umm... its really big and stiff!! 165mm length is great for DH
Weaknesses: Christ they are heavy! 600grams! The spider is so thick I had to machine away part of my MRP so it would fit. Use a wider BB than you planned on and mount the ring on the inside to retain anything resembling a good chainline
Ummm, you can not bend these bad boys unless you have serious glandular probem and a penchant for 20' drop offs to flat landings! Serious strength for DH. Overkill in my case (140 pounds), but thats OK.
These cranks are amazing, They aRE THE STIFFEST THING ON THE MARKET. The spider is not some warmed over X-country spider with a useless ring that does nothing. The kooka spider is splined with double bolts to hold it on. Super reliable and highly recomended
I haven't been on in awhile but I have just got back into the MTB scene. In a separate acquisition I purchased these Kooka Razor cranks along with an MRP chain guide. My question is are these any good? They are actually too big to fit on my Proflex 957 so I am trying to figure out if they are wor ... Read More »
