My only reason for posting this review is to draw attention to the fact that these tires have awful traction on damp or wet asphalt.
This weekend I had my second major wipe out due to lost traction on the rear tire under moderate braking downhill on damp asphalt.
I should have researched more before buying them because in all fairness the Geax website only gives them one start for performance in the wet.
I'm going to swap them out for something that is a better compromise (suggestions are welcome).
Strengths: roll. On flat terrain-no problem-pretty fast tire
Weaknesses: stopping, cornering, turning, using.
Sorry, I see some people love them but I am no fan. I ride single track in SE Michigan. Some climbs and descends going over sand, gravel, hard pack, roots, rocks you know the routine.
These tires corner poorly and stop poorly in the above conditions. Pretty bad in wet conditions too.
I have been riding mountain bikes for over 20 years-bmx for 15 before that. I am not super fast but I am pretty good on a bike in the trails and these tires are pretty bad.
Now if you ride rail trails and pavement then these are going to be great tires

Strengths: Texas summers can be dry and dusty with little or no moisture on the trails and I picked these up as something that would hopefully provide a better ride on loose dry stuff. For that reason alone, they seem to perform as intended, but push them and you’ll find they have their limits. They seem to transition to moist and damp with unenthusiastic results. When pushed in the dry, loose stuff, they demonstrate predictable drift and slide, but give them roots and rocks and the results become less than desirable.
Weaknesses: Damp or wet conditions are NOT for these tires! Add some dampness or even slightly wet and they get unstable and can provide some adrenaline inducing moments. Personally, any application beyond the dry loose stuff exhibits unfavorable mannerisms that do not inspire confidence. On anything wet they will provoke adrenaline spikes and fear. Quick to find your butt on the ground will be the unexpected outcome.
Once notable tip is I found these to be a little better under hard cornering with a slightly higher tire pressure than I normally run. These are not the TNT casing that I’m writing about here. They are a bit more robust than the straight AKA’s I’m referring to here. Under 23 lbs. of pressure these tires had a propensity to roll the tire which yielded disagreeable handling that I can do without. Obviously, higher pressures eliminated this.
Some have stated they do well on dry concrete, but my observations don’t agree. On dry concrete their limits are easily exceeded. They will break loose prematurely regardless of tire pressure. To be fair though, the induced drift remains fluid, predictable, and controllable. However, these are simply my opinions and others will possibly find these traits to be attributes. Two wheel drifts on hard pack or concrete is simply not a desirable characteristic for me personally.
BOTTOM LINE: On dry loose trail, these seem to do the job. You might be able to find another tire that has more favorable characteristics on mixed terrain. They are predictable, but just not the tire I feel inspired to push hard.
Really like this tire! I am used to Conti Race King, and Kenda Slant Six. Made the switch to Tubeless and wanted a combatible tire, so this review is for the TNT version of the AKA. This tire is the faster of the three by a noticable margin. I thought race kings were fast.....the Geax is faster. The front tire tracks really well and holds a line with little steering input. Cornering is very good and predictable. Very similiar to the Race King in that it is hard to break it loose in hard leaning cornering, and when it does start to break loose it is predictable and drifty. The slant six would sometimes break loose without warning. The sidewalls are super stiff and strong which may account for weight, and lower pressures are required to mold to terrain. Acceleration traction is great, while the rear will skid under heavy braking, so a lighter technique is required.
The negatives. Volume is small for a 2.2. Looks and feels like a 2.0. Not sure if it will loosen up over time or not.
Almost impossible to mount on a Stans Rim. Once on though, it sealed up easily and feels very secure. If the bead does not stretch, I'm not sure if I will be able to get it off.
Strengths: Price is less than the competition. TNT casing has tough sidewalls instilling confidence that tears will be minimal, if at all. Fast rolling, very predictable in corners in dry conditions. Hooks up well on rocks. Sets up tubeless and holds air reliably on ZTR Flow rims. Great back tire.
Weaknesses: The small knobs wear out pretty quickly, tire is smoked at maybe 150 miles. They do not track well through mud.
These tires work great through dry Pennsylvania racing summer conditions. I would not run them in early spring or the damp fall. The carcass is quite rugged, I would trust it through the rockiest trails of Pennsylvania. They are a little heavier than some other options but that is the price for a reliable case. I found these tires to be excellent in the corners. The knobs make a tearing noise when they claw for traction at high speed. To me, that inspired confidence as I knew exactly what the tires were doing.
Bought the Aka marketed as a gripy replacement for off road and ride to the trail. If you strictly ride dry concrete these tires work great. Could also see them work well on smooth trails. On rocks, roots or even wet concrete these tires leave quite a bit to be desired. Moved the tire over to the commuter with plans of burning these tires out. Tires are much to expensive for limited traction.

Strengths: Using as back tire only, have a Specialized Fast Track LK 2.1 up front. Set up easily with Stans, very little air leak over 3 months. Very fast, grips corners well. Good on hard pack and loose over hard. Climbs suprisingly well, even while standing on pedals. Tough side walls.
Weaknesses: Braking is only so-so. Wears out quickly. A bit heavy for a 2.0
Very good and fast as a racing tire on hardpack and loose over hardpack. Need to be careful with hard braking (scrub speed a little earlier on downhill before entering a tight. loose corner) Pretty tough tire, no leaks, side cuts or damage after riding numerous rocky, technical trails. Heavier than a Small Block, but I think it corners better. Would not recommend for recreational trail riders.

Strengths: Fast Rolling, great grip.
Weaknesses: No for loose kitty litter
This tire is awesome if you are looking for a fast rolling hard cornering grippy tire. Works amazing on hard pack, gets the job done on loose over hard pack but if it's strictly loose kitty litter they wash out. Great tire for the price when compared to $60.00 plus tires. Not great as a rear tire, doesn't track well but will climb decent if you run it with low psi.

Strengths: There were no problems running this tire tubeless. The tire has good uphill traction on loose terrain when it's new. The outside knobs work well for cornering.
Weaknesses: The center tread wears fast, the tire lasted 2 months of heavy riding.
The tire works well for dry riding conditions. I believe the biggest weakness is the design of the center knobs. The tire doesn't feel very fast and wears out quick. I mounted the tires on a stans converted wheelset with ease. The tires had no visible wobble and the sidewalls seemed stout. I wish the AKA tire came with Small Block 8 center knobs.

Strengths: TNT seals well on tubless rims, light, fast rolling
Weaknesses: Wears fast on tarmac
I bought a 2 and a 2.2 cause i couldn't get a set of Larsens at the time, the 2.2 on the front had way too much grip for endurance racing so i got the bike paired with 2's, perfect for endurance events, fast rolling light and fast, corner well on anything but mud, pea gravel and not too bad on loose sandstone. I liked the feel of the 2.2 so set my trail wheels up with them paired and gave the ignitors the flick.
True the rear 2.0 does ware fast on the tarmac, so keep them for dirt and they will keep you happy, use them for what the Geax recommends and you wont be disappointed.
And they tend to start humming at about 28-30kph

Strengths: Extremely quick acceleration, can be flipped around for traction or another way for speed. Has the ability to run tube or tubeless. Stuck surprisingly well on loose, rocky parts and dirt.
Weaknesses: Hung fast in the corners, but was on the edge of slipping. On turns where I had to lean in deep and hit the rear brake, the tire slid out well, but struggled to regain traction even after the brakes were released. On street, deep corners caused the tire to start humming, signaling the edge of its traction limit. Scary in the wet.
My original bike was equipped with Kenda Nevegals. After replacing only my rear with the Geax AKA tire, the bike felt quicker and climbed smoother. On the hard rocky trails that I make, the AKA is not ideal as a front tire. As a rear tire, it offers good, but not amazing, grip. This tire isn't suitable as an all-weather tire like the Nevegal, but it is very quick for the dry. A racer who rides hard and wants cornering grip should settle for a beefier tire; A racer who wants fast acceleration should consider this, but ONLY as a rear tire.

Strengths: rolls fast and light, aka seated up for tubless setup with a floor pump. I thought traction was pretty good considering it is a semi-slick.
Weaknesses: 2.0 is extremely small for a 2.0, and very little tread. Soft knobs do not last very long. Do not handle low PSI well. HORRIBLE traction in wet conditions.
I've used both the 2.0 and 2.2 for the rear, used the 2.0 for like 2 or 3 weeks before moving up to the 2.2 since there is almost no center tread on the 2.0. Center tread on my rear tire is no almost gone (I have it mounted in reverse for traction though) after about 350 miles. I have not been happy with the performance of these tires much below 30 psi, and hitting a root during a turn can get dicey, but these things really roll fast, so will save my unused one for next race season as a front tire
