Low rolling resistance.
Very fast on road.
Good grip, sure footed handling

sidewall starts to separate from tread after a year of use.

I've used the original GEAX Evolution tires for years, and they provided sure footed traction and low rolling resistance on pavement.
They became my standard street tire.
Not really an offroad tire, but provided decent traction on grass, dirt, loose gravel, but not like a good pair of knobbies.
Great all around tire, but more suited to urban assault and street riding.
Excellent low rolling resistance and cornering grip on concrete and asphalt surfaces.
Tread lasts forever, but the sidewalls would start to unravel, and the tread would crack and separate from the sidewall after a year of use.
Sadly, GEAX has discontinued the original Evolution, and has come out with the Evolution II, with an entirely different tread pattern and sidewall construction.
Rolling resistance is about the same as the original, but makes a strange hum on asphalt.
Handling and traction are about the same as well.
The downside to the Evolution II is the tread pattern is too fine, and lots of small bits of rock and debris constantly clog up the tread like a magnet.
On every ride, I would have to stop at least once or twice to pick rocks out of the tires because they were making ticking noises with each revolution, making me think I may have picked up a nail or thorn.
As another reviewer noted, something has gone downhill with GEAX's quality control.
I had three badly out of round tires; a Roadster, and two of the new Evolution II's.
They were not rideable, and were returned.
They were extremely difficult to mount, almost as if they were slightly undersized.
I almost broke a pair of tire levers trying to get them on!
I suspect this undersizing is causing the tire to distort badly when installed on the rim, resulting in a seriously out of round installed tire.
I'm also very disappointed in GEAX's quality control.
I never had a problem with any tire being out of round, including numerous pairs of the original Evolution.
However, GEAX's current line of tires has some serious quality control issues.
I've since lost confidence in GEAX, and will be testing out a pair of Kenda K-Rads.
My rating score reflects only the original GEAX Evolution tire.
The new Evolution II is not recommended, unless you are lucky enough to get a pair that isn't out of round, and like picking rocks out of your tires constantly.

Great tyre for on road or hard packed tracks, Great commuter tyre works great on wet roads, looks good to best tyre I have ever used for the money!!

None

If your looking for a tyre that does everything then this is as close to perfect you can buy!!

Pretty much every hybrid tyre out there!

Causes your bike to not only move forward, but up and down.

maybe it's just bad luck, but of the two i got, neither is round. there's about a 6 inch length where the sidewall works its way down to about a half inch shorter then it should be, and them back up to normal.

well, at least two of these tires left the factory with a rather serious defect. i personally will avoid geax for a while now as i'm not real keen on paying folks to let me be their quality control.

I've never used any other not round tires.

Fast rolling, quiet, durable, basicaly puncture proof, great for road use, looks funky, can also be used on dirt.

not a true dirt tyre, a little heavy.

I baught these because I needed a tyre that I could use on the road that would not get punctures and would last a long time while still allowing me to ride on dirt occasionaly.

They have a smooth profile but a deep tread which allows them to be used on road and hardpack trails. They have little climbing traction but better sideways grip than might be expected.

4 years of daily use both on road and trails is a testament to thier durability and surprising off road ability.

Low rolling resitance. Puncture resistance. Durability. Very good value for money.

Heavier than most others.

Just clicked over 4000km commuting on these, mostly on bike paths. Plenty of glass on these and I have had only one flat. This was due to a piece of wire through the gap in the tread, just bad luck really. Tyres still going strong, though some signs of cracking in the side walls, I still have no intention of replacing these any time soon. If and when I do it will be with another set. Awesome for there intended use, commuting on hard surfaces. Do yourself a favour, get a set and forget about flats.

THESE ARE ONE OF THE HIGHEST RATED TIRES OUT THERE...THEY LOOK GREAT ...PERFORM GREAT....IF YOU WANT A GOOD ALL AROUND TIRE GET THESE TIRES....IF YOU ARE ONLY A TRAIL RIDER OR RACER THESE AREN'T YOUR TIRES....FOR THE OTHER 95 PERCENT OF PEOPLE WHO OWN MOUTAIN BIKES THESE ARE PROBABLY ONE OF THE BEST TIRES YOU CAN BUY.

The missus was complaining that her MB was hard to peddle. Went for a spin and noticed nothing out of the ordinary other than the typical issues with full on off road tyres.

Put a set of Evolutions on and problem fixed.

Put a set on my MB (was alternating between knobbys and slicks) as I was sick of changing tyres, most of my riding to date is on road or made tracks and the slicks just weren't cutting it when things got loose.

So far I’ve done about 100km and am suitably impressed. They work remarkably well off road in a variety of surfaces. Some semi-serious off road riding today started me thinking that unless you were in real loose or muddy conditions, these tyres are all you want. Their versatility is excellent.

Other than the sheen coming off the tyre though use, you can see no wear at all. The mould centre rib and dimples are totally unmarked. Expect long life from the tyre and this is reinforced by the comments of others.

One question I have, after having just studied the tread pattern, is are they semi-directional. The majority of the grooves in the side tread are angled in one direction. Mounting the tyre in a particular direction would make the tyre tread self cleaning (like a tractor tyre in mud). Has anyone else noticed this aspect or agree.

After 3Yrs use I would have to say durability! Grip(on hard), roll well, smooth, quiet, deep tread, value!

Still a bit heavy but given life...? Mine do have cracks at the base of each tread block... they havent actually caused an issue yet but its in the back of your mine when hammering around the bitumen road.

This is a 3year follow up to my review below... I still am on those original tyres!!! Although I dont do huge k's on this bike they show very little wear and still perform as great as when I first got them. There are cracks at the tread base but they have been on a while now...perhaps just "molding to the road" creases ;-)
Go fine on hard pack dirt paths etc, and dry or wet roads, obviously not for loose or off road.
Fantastic value when they perform so well and last so long!
Go get em!

A great touring tire for mixed road conditions. Very versatile: they roll really smoothly and buzz-free on-road, yet they still hook up well while turning on gravel and dirt. Very resistant to punctures because of their thick smooth centre strip.

Heavy - 800g each, but then that's because they need a lot of rubber to provide those strengths, so..... it's a worthy trade-off.

I used the GEAX Evolution for a 6 day self-supported road tour that involved a lot of dirt roads. As you can see, I've used a lot of slicks! The fact is you need different slicks for different purposes. Skinny and smooth (therefore light) for road-only use, wider with some knobs (therefore a bit heavier) for mixed (asphalt/tarmac)road and dirt. Any tire that tries to do both road and dirt will involve compromises. Eg, The Bontrager Revolts buzz on the road and puncture easily. The IRC Mythos XC Slick is really great except it buzzes on the road too. What I like about the GEAX Evolution is that it actually does both well - it rolls completely smoothly on the asphalt/tarmac road, AND it holds well on the dirt roads AND it resists punctures simply because it's got so much rubber between it and the road. So, I think it's a great tire. The weightiness is worth the benefits. It's even relatively cheap. And if I had to, I would even take it onto serious singletrack (eg, roadside trail discovery) without fear of the trail killing me. You shold buy this tire if you are doing a lot of riding that involves both smooth asphalt/tarmac roads AND dirt roads. I haven't had it long, but it certainly looks like it'll last a long long time!
