Date Reviewed: August 18, 2009
Duration Product Used:6 months
Strengths:Cheap and durable
Weaknesses:Everything else...
Similar Products Used:Kenda Karma, Hutchinson Python
Bike Setup:Giant XTC Composite
Bottom Line:These tires are durable and cheap, but they leave everything else to be desired.

I have tried multiple inflation levels and cannot get anything to work. The tires are either over-inflated, bouncy all over the trail, slipping on roots and hard to predict in the corners or are too soft and suffer from regular punctures.

I have used these tires enough and have walked away. Even as back up tires for racing, its better to enjoy the time you have riding and choose something else. If you already own them, ride them to dust and move on.

Favorite Trail:Riverside state park
Duration Product Used:3 months
Price Paid: $35.00
Purchased At:Price point
Strengths:Best climbing tire I’ve used to far
Good in corners (when not breaking)
Tough as nails (sidewalls and pinch flats, not punctures)

Weaknesses:Traction while breaking, more like a 2.0 than a 2.1
Similar Products Used:Kenda:blue grove, Nevgals, Karma. Panarace: Smoke/Dart IRC Mythos.
Bike Setup:Short travel XC full squish
Bottom Line:These tires are so very good on most conditions, but so very bad in others. They corner relatively well, but they are kind of all or none. They rarely fail to hook up, but if you do lose traction, all control is gone. On dry/loose descents, as soon as I try to feather the brakes to control my speed, the tire goes into a slide and I experience the aforementioned total lack of control. This tire works great for climbing. I accidentally ended up on a rocky abandon railroad trestle with big chunks of volcanic rock. I can’t believe I made it home with my tires still in tact.

I’ve been testing out a lot of tires in preparation for a 100-mile race where I expect jagged, rocky terrain mixed with dry, loose sand and gravel. With the combination of strong side walls, pinch flat resistance (I have had a puncture flat with these)and climbing traction,I think I’ve defiantly found my back tire, but I’ll have to keep looking for a front tire that will perform in sand. I may use my mythos or dart front, or try a Mibro 2.25, Or a MK 2.2.

Strengths:Great traction, little resistance on asphalt, cheap too
Weaknesses:none...
Similar Products Used:Kenda something (stock on my bike)
Bike Setup:2006 Giant Rincon (canadian model)

Pretty cheap bike but does the job
Bottom Line:Bought these because my other tire was completely slick. They were much easier to install than other tires I had played with.

Since I do a lot of road with my bike I inflated them at 50 pounds and even then, they still had great traction on dirt and sand. However, while cornering, it could have been better.

At 40 pounds it was perfect, except still that cornering problem (however those are 26 x 1.96 while I was used to have 26 x 2.10), but it was almost not perceptible.

Anyone who rides in trails and on road (I personnaly do about 50/50) would like it and at about 40 bucks, it's a very good value.

Similar Products Used:Schwalbe Racing Ralph+Nobby Nic, Panaracer Dart+Smoke, Conti Explorer

Good traction even on muddy ground.(at last marathon I climbed in the Mud hills, where nearly all others had to walk with their CC-Tyres).

Duration Product Used:3 months
Price Paid: $30.00
Purchased At:Came with bike
Strengths:Good traction on hard stuff. Corners well on hard surfaces. Good wear. Pretty good in mud.
Weaknesses:Horrible on loose dirt or gravel. Refuse to turn at low speeds on even slightly loose surfaces. Squirrelly on steep descents. In loose pounded dirt they will pretty much drop into whatever groove they want whether you want them to or not.
Similar Products Used:Velociraptors
Bike Setup:Cove Handjob, xt drivetrain, Hayes HFX9's, Reba fork
Bottom Line:I had these in the 1.95's. They're pretty good as long as conditions are hard. They climbed and cornered well in hard conditions and also hooked up well in mud.

Dry loose conditions are another story. I felt downright dangerous on these in loose dirt, loose over hard, and gravel. If you happen to get the rear out of the groove and into the loose leaves or pine needles, kiss traction goodbye. On loose corners any amount of lean leads to a washout and if you try to slow down they just wont turn. In late summer with deep dust and chewed up trails they not only have no traction going up, they're just plain dangerous coming down.

If all you do is ride in mud or hard, wet conditions these probably would work great. They probably would also make a decent early season/Spring tire before trails have gotten dry and chewed up. If, however, you ride in anything loose then stay away. They aren't worn hardly at all yet but I'm getting rid of them, they're just too unpredictable.

Duration Product Used:3 months

Strengths:Little rolling resistance, light weight and relaively cheap. Seems to handle virutally the same at high pressure as medium pressure. Good for climbing dry hard pack.
Weaknesses:Performs poorly on descents. Can deflect erradically when dealing with rocks and is very unstable in loose gravel terrain - border line dangerous. Wet conditions also yield poor performance all around.
Similar Products Used:Panaracer Fire XC, Hutchinson Pythons, WTB WierWolf, etc...
Bike Setup:'04 Santa Cruz Blur
Bottom Line:As much I was enamored by this tire for it's general climbing prowess and light weight the truth is once you get 20% wear on the tire it's weaknesses become exagerated and it's to much to bear.

Descents on wet dirt will train you to keep you eyes peeled for the nearest exit off trail because if your speed gets too high that is where you are headed. Dropping into any sort of loose gravel at speed is terrifying beyond reason.

Similar Products Used:Michelin Country Trail
Bike Setup:Giant NRS-G, Rockshox Reba, Shimano XT drivetrain, Avid disc brakes.
Bottom Line:The tires are light, but that's not the point. Uphill climb is good. However, you can lose confidence going downhill. The gaps between side knobs are so far apart that any small rock or stone can cause the front tire to deflect when you hit that gap.

Tires are good only on hard packed trails. Not recommended for rough and loose trails.

Strengths:Pinch flat resistance. Durability.
Weaknesses:Probably not as fast on pavement as other tires. But then again, I never have problems keeping up with the other riders.
Similar Products Used:The tires that came with my bike - Giant branded 26x1.95
Bike Setup:Giant Iguana - pretty much stock, except the tires and Velocity Cliffhanger front rim.
Bottom Line:Got the front wheel fitted with a Serac (steel bead) after I busted the original tire in a crash. After having 6 pinch flats on the rear tire (I'm a bit of a heavyweight), I got that replaced to a Serac, too. Since then, I had one flat exactly, and I have ridden about the same distance as with the original tire. I ride in the desert a lot, which means many rock gardens and sharp stones - Many times I hear the tore getting scraped against a sharp rock and I think "there it goes", but nothing happens. Currently, I don't think I need anything more sophisticated (read "expensive") for my bike and ride.

Purchased At:LBS
Strengths:No pinch flats, good traction
Bike Setup:Santa Cruz Blur
Bottom Line:I ride east coast single track -- trails that are rocky, rooty, fairly technical, moderately packed loam (low traffic trails, so not hard packed), well drained (not much mud) and with few fast descents. These are excellent tires for this type of trail. (I'm not saying they're not good for other conditions -- I just don't know.) Traction in various conditions is good, and the pinch flat resistance is excellent. I'm 175 lbs and I often ride 25 psi without a problem. My wife is 125 lbs and she often rides less than 20 psi. Neither of us has had a flat in three seasons. I'm not saying you can slam into a rock at the end of a screaming downhill -- the trails I ride are fairly technical and so fairly slow. But there are rock gardens, random rocks and small sharp stumps galore, and the Seracs handle it all reliably. Contrast the Kendas that came with the Blur -- a stump ripped open the side wall after about three rides.

Strengths:Great climbing ability. In my local hill climb i have shaved off 8 minutes of time using these tires (from 47 mins to 39 mins). No other changes were made to my bike and, at 42 yrs old, I'm definitely not stronger! Most of the riding I do is climbing on packed single track with occasional loose rocks, 5-12% grades (If you're from Denver think Alderfer/3 Sisters, White Ranch, Bear Creek Trail, Colorado Trail). One trail (North Table Mountain) has a section that is about 18% grade with loose rock and these tires definitely lose traction in that case, whereas my Kenda Nevegal 2.35's didn't. Having said that, I can still make it up this section with my Seracs but it's tougher than my Nevegals.
Weaknesses:They lose traction climbing steep grades with loose rock. Will get twitchy in loose, rocky descents. Seem skinny for 2.1s.
Similar Products Used:You name it, I've tried em.
Bike Setup:1) 2006 Titus Moto-Lite, SRAM X-9, avid discs, fox rp3, fox talas rlc.
2) AMP Research B4, XTR, Risse Racing Genesis shock, Manitou Elite fork.
Bottom Line:If you want to shave time off your climbs in hard pack conditions, this is a great tire. Not as confident as my Kenda Nevegal 2.35s on the downhills but having said that I'm not afraid of running these hard while going down. Keep in mind that I am predominantly a cross-country rider and not a downhiller.

Bottom Line:I have to agree with the negative reviews of this tire. Maybe this a "jack of all trades master of none" tire but it performs poorly on loose, dry trails (which I mostly ride). I constantly slip in sections I never did with other tires (both on climbs and descents). I agree with the reviewer who said they can be dangerous under certain cicumstances. They are OK in mud. You can do better if you are looking for an all around tire.

Weaknesses:Low volume, does not handle rough stuff well
Similar Products Used:Lots
Bike Setup:Specialized Epic Pro
Bottom Line:I really wanted to like these tires. They rolled so well and climbed great. On the first ride I cut almost 10 minutes off one of my usual eight mile climbs. The problem came on the downhill when the trail got rough with rocks and ruts. The tire does not absorb bumps well. Even on my full suspension, the tires felt like they were bouncing off rocks instead of rolling over them. I tried different air pressures, shocks settings etc., but could never feel comforatable or in control like I had with higher volume tires. If the trail is smooth and buff, this is a great tire. If you have rocks on your trails, you might want to try something else.

Strengths:This tire is an all around trail tire; it performs fairly well on easy single tracks.
Weaknesses:Being an all around tire means great at nothing. High rolling resistence on pavement compared to other MTB tires I'd ridden. Weak traction on average climbs and loose stuff during descent. Obsolutely refused to steer during downhill (scary!!!)

Bottom Line:This tire is an all around tire that you can take it to anywhere. It has good puncture resistence; never had a problem over 100 miles. However, it has higher rolling resistence on pavement compared to other MTB tires I'd tried. It performs poorly on loose gravel. I'd experienced numerous skidding on average climbs. It won't steer on high speed descents-watch out!!! (Panaracer Dark/Smoke combo performed better.)

Even when you can get them to break loose they recover when your bike shifts direction or momentum. Very good traction in everything except loose rocks on steep uphill. Not as quick a bite as Raptors on front but better for speed and agility and going uphill. Will handle just about all you can toss their way. They look wider when you are seated than from side on, just the way the tread spreads out on the sides I guess. Use in reverse tread pattern on the rear. At 185 lbs I find them best off-road at 38-40 psi for good grip and no flats.

Bottom Line:I bought these on eBay for $20 just to try them out and was pretty happy with them. They are durable, wear fairly slowly, and perfored well in every condition that I tried them in. However, for almost every type of terrain, I prefer the Kenda Nevegal and Specialized Roll-X tires. However, the IRC's are fairly easy to find on-line at a pretty cheap price so they're worth a look.

Purchased At:Cambria's - then shipped to Oz
Strengths:This is a follow up from my original post 18+ months ago (refer below), and I still love these tyres! Only difference is that I now use the 2.1's (my previous review was on the 1.95's). Despite the additional rotating weight, the extra few grams in the 2.1's barely seem noticable (580gm vs 525gm) and has not added to the time it takes me to complete my favourite loop. I am yet to pinch flat with the 2.1's, probably testimony to the larger air volume (in 18 months of using the 1.95's, I probably pinch-flatted 2 times).

It is also worth mentioning that during summer time, local trail surfaces feel like you're riding on ball-bearings (aptly named, "pea-gravel"). Despite a couple of Summers in these conditions, these tyres continue to do themselves proud.
Weaknesses:Getting them in Australia (waited a couple of months to be told by LBS that they are no longer imported into Oz by the IRC Distributor (which hardly qualifies him as a Distributor does it!??). Placed an order via the net with Cambria and they were delivered to my front door less than one week later (and the 'postage inclusive' price to Oz was actually cheaper than the MSRP I paid for my first few pairs bought locally - damn!).
Bike Setup:Giant NRS1 - stock, apart from shimano rims.
Bottom Line:As long as IRC keeps making them, I plan to keep using them - very happy with the way these tyres suit local conditions. I have placed an order for a custom 2005 Titus Racer X100 (expect to pick bike up from the Norcal ~ April/May '05) and that bike will also be shod with these tyres - enough said.

Strengths:Light

Great climbing, braking and cornering traction
Weaknesses:Doesn't shed mud especially well, but no worse than average.

Climbing and braking on wet roots is average.

Minor lug squirm on grippy hardpack, but traction remains excellent.
Similar Products Used:I currently have 20 tires in my garage and all of them are still in service. There are plenty more that have come and gone.
Bike Setup:Titus QuasiMoto set up for long-travel cross-country (under 30 lbs., narrow rims).
Bottom Line:The Serac has the traction of classic all-around tires like the Panaracer Fire, but the low rolling resistance of a race tire - actually, there are "all-around" tires with far less traction and "race" tires with more rolling resistance. These are the tires I choose when I'm unsure of what I'll encounter. They're always a good choice, sometimes the perfect choice, and never a bad choice.

Considering the Serac's light weight and low rolling resistance, climbing and braking traction are mostly excellent, but drop down to "average" on wet roots; a more paddlewheelesque tread pattern would be better for this, but would almost certainly have more rolling resistance. Cornering traction is superb. There's a little lug squirm when the bike is really leaned over on high-traction hardpack, but it doesn't get scary.

There are lighter tires, faster tires, and tires with more traction, but I haven't found any that score so highly in every category. From what I've seen, the Serac is the new standard in all-around tires with a bias toward light weight and low rolling resistance.

Similar Products Used:Mythos, Dart/Smoke, Ritcheys, several others
Bike Setup:'01 iDrive, Manitou Six Deluxe, 2.1 Seracs, LX/XT mix, '04 firex SL, etc. etc. etc.
Bottom Line:I thought I'd found THE tire with the Mythos. Unfortunately, the sidewall developed a split (I think my homemade stans ate the thing) and I was forced to try something else. The Mythos fronts were OK, but never inspired confidence, while the rears climbed pretty well in wet, rocky connecticut. When I tried these, I was skeptical. With the small, angular knobs and the un-conventional(for me) non-directional use, I figured why not.

Was I surprised at how well these things perform. They outperformed the Mythos in every category except in loose sand or sand over hardpack. I can consistently out-climb my buddies and they can never figure it out. Of course, I DO have the best climbing technique ever witnessed on a bicycle....NOT. But, they all think big knobs are better, so they lose out.

They work well climbing wet babyheads, wet roots and granite outcroppings as well as loose dirt and hardpack. I've NEVER had a flat with these (running tubes) and I'm 6'1" 190lbs. I also love that I can just swap tires front to rear. I was getting tired of buying one rear tire at a time. Oh yeah, I didn't think I'd like the red sidwall, but I love it now. It looks old school.

Thanks IRC. These things rock.

5/5 for the value I got. I think my price was just introductory as I haven't seen these less than 35 bux for a while.

Strengths:Durability. Knobs stay on & they are reasonably flat-resistant. Decent climbing traction.
Weaknesses:Everything else. Tire breaks loose unpredictably when scrubbing speed on downhills & trying to set-up for technical sections. Absolutely refuses to corner on anything but hard-pack at low speed. Washes-out when conditions get the least bit loose or when riding at speed. I find myself constantly having to weight the front end when cornering, and leaning into corners inevitably results in taking soil samples.
Similar Products Used:Panaracer Fire XC 2.1, Bontrager Jones, various Specialized tires, Continental Vertical & Survival
Bike Setup:KHS FXT Pro, 4" front & rear, hydraulic discs, Shimano variety-pack
Bottom Line:These tires are dangerous!!! I have taken more spills on these death-traps in the last 2+ months than I did all last season on Panaracers. Decided to try them in lieu of Panaracers because I had been getting alot of puncture flats. Still got flats, & now my bike handles lousy!!! I am running Stan's NoTubes now, so flats are no longer an issue. I'll be going back to Panaracers... Either the Fire XC, or the new Cinders. Bottom Line: If the only choice I had was to run these or slicks, I would use 'em, but there are plenty of good tires out there, so I'm going to take these ( almost new ) tires off my bike, drop another 60 bucks on tires & ten bucks for some more Stan's sealant. They are THAT BAD; a complete waste of money. They are DANGEROUS for riding anything but the tamest of trails at walking pace, and I would not recommend them to anyone.

Bottom Line:I borrowed these tires from Youthcycing.com president Jeff Buerman at the Norba at Snowshoe, WV. It was muddy as hell and very rooted, alas I didnt have with me any mud tire that could handle the roots as well (all were 1.7's that i brought). Tried these, havent wanted to give them back. They are phenominal tires, they work in conditions ranging from West Vigrinia mudd and roots (slimey), to Southwest Michigan sand, to Durango loose over hardpack. I run them as tubeless on my Crossmax Sl ust wheels with Stans tire sealant (great stuff) and have never had a problem running them at 25-30psi. I run them back and front with great results. One great tire for any one riding cross country in Michigan, or anyone riding were there is not a huge amount of hard pack, great for racers with ust and stans (super light tubeless tire).

Bottom Line:Immediatlly noticed the lower rolling resistance after 3+ years on the Mythos. Hooks up as well, better, in hard fast turns. Equal grip climbing in loose rocks, limestone outcroppings. Slightly less stability in loose sand. Seems sensitive to front wheel weighting - more so than Mythos - for directional control in sand - but equal traction - if there is such a thing (sand). Did notice the "feel" of loading the side knobs - in hard fast turns. Difference than Mythos, as bike "rises" up on the knobs - but hooks up really well when into lean / banking. Great on hard technical, easy and fast on hardpack. Watch wet roots. Somewhat more slippery - obviously from closer center tread knobs - compared to Mythos. Really happy with change, and, an IRC fan - from experience.

It handled hard pack, loose rocks, roots, rock gardens, and sand with ease. The tire was predictable in that you could feel how it was tracking. I was able to climb better (I originally thought this might be due to better skill, but then realized that I have none and it had to be the tire!). Since the trail conditions were dry I can't say how it will perform in mud, wet roots or wet rocks, but I'm looking forward to finding out.

Bottom Line:I have the Serac XC 1.95's on both wheels and have now loggeed in about 300 miles on these.

The front tire hooks up really well, a tad better than the back tire. I have ridden them over most conditions and they really hooked up nicely except for on sand...they got really squirly on that. (Big surprise...what doesn't.) They shed mud pretty well considering how tightly spaced the lugs are. (Although not as well as my old conti traction pros.) Bottom line is that these are really good tires and my confidence gets boosted every time I ride on them. I keep the pressure at around 45-48 psi and use ultra-light tubes. So far, no pinch flats, snake bites, or air pressure loss. Bottom line is that you won't go wrong with these tires.

Bottom Line:My dealer was well stocked with IRC. I can't speak from personal experience-but after reading enough negative reviews here of the Mythos and Notos and cornering/washouts (hate that) decided to try the Seracs instead.

Best tire I've ever ridden. Tracks fast and true. Climbs like a monkey too.

I've found its great with:
-rocks
-roots
-gravel
-grass
-pavement (for a xc tire)
-cobblestones
-packed sand

For me it corners with precision and control. I've never been more assured while cornering. (So unlike the Team Controls my bike came with.)

But I can't really speak for mud yet. And I won't worry about snow (i ain't interested).

I've washed out one time-but I was asking for it. I was trail riding in a forest which was an ancient beach (really). So a particular berm I took too fast was essentialy a small, deep sand pit. Before I knew it-out she went.
But I would be surprized if there is a tire out there that can handle deep beach sand (at speed).

Its a keeper.

They run down singletrack nicely, but slip a bit climbing over roots and rocks (dry roots, even). Perhaps because they are made with low rolling resistance. They slip and break loose in a fast turn fairly predictably, but a bit sooner than I would like. I would break it down this way;
climbing: 5
rolling on pavement: 5 (for a knobby)
general single track: 4
