From what we understand, some folks race both uphill and down. Even more ridiculous, the Maxxis Aspen Tire is specifically designed for these wackos. The combination of high volume and low profile lugs makes for a smooth ride and very little rolling resistance, and the dual-compound, directional lugs grow to monstrous proportions at the corners, allowing you to lay the bike way over in high-speed turns without losing traction.
These came on the bike.
They are a fast tire but unpredictable.
Great for long distance mostly straight riding.
Not so great for pushing on down hill twisty single track.

Strengths: I always liked semislicks, these remind me of a Michelin Jet tires, but thes are like a turbochrged version of them. Despite the reviews, I am using it in the front with a maxxis superlight tube and have no problems, I like the way it feels, more "flat" unlike say a Python, more round, I tested it in rough terrain, rocks, loose, hardpack, every dry condition out there and to me, it´s a great front tire too, combined in the rear with a Kenda SB8 Tubeless, the setup rolls fast and can handle anything, agrressive riding no problem. Rode it pretty gnarly and felt predictable, no lack of bite, or scary as some mentioned. I can handle small knob and semislck tires well, can´t stand slow rolling tires. Strong up front, stable.
Weaknesses: A bit prone to snakebites in rear if used with tube, in the front no problems. weight in my scale 580g, it´s allright for me.
Bottom Line:
Great tire front or rear. If u have the technique to handle it. Predictable, more flat surface, good braking, good feedback, I thought it´d be sketchy up front, but not at all, nice feeling, and rolls fast, rolls smooth, bites better than a Python or a SMB8. but also enters that fery fast range of thread design with a little more bite. As I said reminds me of a Michelit Jet S but with better perfomance, excellent straightline speed, stable, quiet.

Strengths: rolls fast, handles single track way better than expected, light, stable, predictable
Weaknesses: a bit of slip climbing steep gravel road
Bottom Line:
Well worth the price, cheaper, faster, and a better turning tyre than the CrossMark
Strengths: Greta tire, using it as a rear tire and it does eveything great, good grip climbing, cornering no issues. Does not wash out in sand too much
Remember it is a fast rolling low profile tire and I am reviewing it as such.
Braking, cornering action good. Sometimes tend to start skidding a bit under fast braking. (kinda riding the dirt) still contralable and easy to correct.
I now have 600 miles on these tires and there is slight wear dtectable. This is a lot of climbing and descending on socal fire roads. I think they are good for at least another 600 miles.
Weaknesses: None really
Bottom Line:
Came standard on my bike as a rear tire, will purchase again after it wears out.
Can't comment on wet perfomance, have not seen any rain in socal in the last 4 month.
Strengths: Low resistance. Great on the road or rails/trails
Weaknesses: Traction
Bottom Line:
Traction is terrible. For my style of riding it is actually dangerous. I have absolutely no confidence cornering in any conditions with this tire. On the rear, the tire spins out on anything steep or hard (rocks/roots). The weaknesses become more and more obvious the faster you ride, making this a questionable choice for a race tire in my opinion. This tire may be just fine for someone who does not like to push their luck like I do.
Weaknesses: 5 pinch flats in a row, thin, skidding too often, not for rough terrain
Bottom Line:
Definitely not my cup of tea, this tire can't take any beatings and rough rides, not happy at all, only good thing is low rolling resistance.

Strengths: Lightweight, fast acceleration, fast rolling. Good cornering and traction for how fast and low profile they are. On hardpack, tacky, or loose over hard these are good fast race tires.
Weaknesses: not heavy duty enough for everyday trail riding. After a few months kevlar beads are visible on the sidewalls. Keep these as "race tires only" and you will be good. Sidewalls gash easily. Stopping power not the best - I skidded the rear on these more than other tires.
Bottom Line:
they are lightweight race tires and for that purpose they do a great job. on race day you can go fast with these. What you gain in speed is the durability found on heavier tires. I have sliced a sidewall and punctured the top of a tire after one season these tires are ready to retire. vs the heavy nevegal i can run those for a long time without replacing.

Strengths: Great Traction on the trails, low rolling resistance on pavement
Weaknesses: None as of yet
Bottom Line:
After getting a few rides under the belt with these suckers, I'm extremely happy with them. I feel far more confident on the Aspend than I ever did on the S-Works tires.

Strengths: Light, fast roller.
Weaknesses: Very Weak side wall and overall durability. Terrible cornering. Possibly worst front tire I have ever had. Rear does not grip on steep rocky inclines.
Bottom Line:
Would NEVER EVER buy again (came with bike). Not olny do tey rip pretty easy but I cannot corner at any speed when they are on the front tire. If you want a fast roller that actually grips try the specialized fast tracks (and they come with a warranty)

Strengths: (this is for the 2.1 Exception 120 tpi)
I'd like to echo what Zacharia has said below. Excellent rear tire in all conditions. Truly amazing wear too. After 6 months of riding 4x week,, there are still nice edges on the tread.
Weaknesses: Sidewalls are a bit thin, I've never punctured one, but when installing non UST tire tubeless, the sides leaked air a bit,, just had to leave wheel on its sides for a while and let sealant do its magic.....
I also found that the tire had a bit of lateral roll at lower pressures(thin sidewall),, I put about 30 psi and it is not an issue anymore.
Bottom Line:
My go to tire for rear, wouldn't try it up front for my local conditions, currently have a Rocket Ron up front.
I love it and highly recommend it!

Bike Setup: Intense Spider 29, 1x9 XTR cranks, Marta SL, Crossmax 29, etc.
24.5 lbs
Strengths: Rolling resistance is notably less than other tires. Grips well on damp to dry conditions. Felt like it was worth gearing up one gear just about everywhere. Tread wears like iron.
Weaknesses: Is sandy and dusty conditions this tire slides out a lot. Very weak sidewalls. 4th race of the season, and 4th race on the tire I blew out the sidewalls in a fairly mild rock garden. Stan's couldn't seal the gash and the tire wouldn't stay on the rim even with a tube installed. I had to withdraw from the race, on my home course.
Bottom Line:
Fast tire in the right conditions, but the low weight comes from a lack of material and durability, not any special construction method.

Strengths: -Incredibly fast; going straight, turning, off-camber, though light mud, climbing
-Each tire weighed 480 grams
-Dropped 1/2 pound of rotating weight off my bike
-Mounts and seals well with Stan's NoTubes sealant
-Inspires ultimate confidence in dry, hard pack conditions
-Great compromise of price, weight and rolling resistance
Weaknesses: -Kicks dirt up in your face and backside
Bottom Line:
Maxxis Design Engineer Bryan Holwell hit the nail SQUARE on the head, with this tire. The Maxxis Aspen 2.1 tire is a product of pure science and diligent rider feedback, namely from Maxxis XC Pro Geoff Kabush. Many XC race tires lack in some crucial area...but the Aspen exceeds in every SINGLE department. The trademark "Chevron" center rolling blocks grip uphill like a Sandrail Paddle wheel, while the semi-aggressive side and transition knobs make for an excellent-cornering tire that digs into the terrain, while inspiring confidence to go even faster. It never wanders, squirms, or fail to claw away at that off-camber rut. Braking traction is fairly good - as long as you modulate your brakes evenly. Even gliding through sand is a non-event. Give a good spin on the cranks, and this tire just wants to keep rolling and rolling. Simply amazing.
I have tested ALL comparable XC race tires, and the Aspen smokes them all...with sub-500g weights, blistering speed, affordable price and even rock garden manageability(make sure pressure is between 28-32psi). I will start a 6-month update thread in MTBR, once I get to that point. In the meantime...I'm going for another ride!!!

Strengths: light, fast
Weaknesses: mud, weak sidewalls
Bottom Line:
Rode these only a few times...3-4 races and 6-8 trail rides. Tread barely worn and sidewall blew out sitting in the house. Better in the house than on the trail I guess, but disappointing.
