$8.00 | | Strengths: | Great resistance to cactus and thorns in general | | Weaknesses: | Seam splits | | Similar Products Used: | Slime tubes and nearly any self sealing tube brand | | Bike Setup: | 07 epic with bb7 discs, xc race bars... rest is stock for now... | | Bottom Line: | These tubes are good at times and horrible at other times. The inner valve locking mechanism on the presta tubes are horrible. Even when tightened they do not stay tight and at times unscrew completely from within the valve stem. Very Very good resistence to flats from cactus or thorns. You might lose a little pressure but just pump up back at home and it usually holds. USUALLY.... I just bought about 4 new tubes of this type and the first two I installed SPLIT AT THE SEAMS(as afformentioned by other riders). I mean one is ok, but two... From that batch I had one more split at a different seam. Of course the shop was quick to give me new tubes, but why bother. I won't buy any more specialized self sealing tubes. These are subpar except for the very few tubes that perform exceptionally. 1 chili for value due to the fact its costing someone to replace all those returned tubes. Overall you might get a good tube, but you might get a tube splitting at the seams. | Value Rating: Overall Rating: |

$7.00 | | Strengths: | None, unknown.
| | Weaknesses: | Bad valves: can't fill it with air. Bad sealant: can't let air out. Heavy. | | Bottom Line: | Since the diameter of the presta valve is so large it wouldn't go into my pump. This might not have been such a problem if there were any threading for a retainer nut to hold the valve to the rim. But Specialized went with the cheapest possible valves instead -- no threading, no retainer.
I have a very common floor pump by Wrench Force and, after messing with it for 20 minutes I was able to get a tiny bit of air in, but it was leaking air from the pump/valve connection since most of the valve was inside the tire area. I even tried pushing from the other side but it wouldn't go in. Are these "specialized" presta valves? Do they only work with a "specialized" pump?
Also, don't plan on letting air out, all you get is slime out of the valve. I noticed this when trying to put them back in the box to return them to the store. I even held the valves upward and away from the rest of the tube. Nothing but slime came out.

Goop leaked out of several of the punctures from both sites. I thought I had a sure flat, but they sealed right away. I have since ridden well over a hundred miles on them, including a 24hr desert ride. They are still holding up with only needing 20lb of air once a week. I have already bought another set of tubes, but am now wondering if I will ever need them. Try these tubes if you ride in the desert with cactus or sand burrs. | Value Rating: Overall Rating: |

I have had to replace several Airlock tubes over the past six months or so. One day the LBS was out, so I bought the blackburn tube ($10!) with self sealing liquid. I've been riding on it for a month without a single flat. The airlocks don't make it that long. I think it may be that the airlocks liquid is just too runny.

$8.00 | | Purchased At: | Online | | Strengths: | The tubes worked exactly as advertised. I received a large puncture from a sharp rock while travling downhill. Not only did the tube not blow but it leaked slowly allowing me plenty of time to get to the bottom of the hill and re-inflate the tire. Re-inflating the tube was a snap, there was not any problem re-inflating the tube. Once re-inflated I was able to ride the bike as fast as I could pedal another two miles home. | | Weaknesses: | None observed. | | Similar Products Used: | None, this is the first tube of its kind I have tried. | | Bike Setup: | Thirteen year old Schwinn Frontier hard tail with low-end Shimano components, brand new Specialized MTB tires. | | Bottom Line: | I will buy two more of these tubes.

Seals rather slowly | | Similar Products Used: | Slime tubes, heavy duty tubes(these are over a pound per tube!!!!!!) | | Bike Setup: | XC bike. sun cr-18 rims. regular rim tape. panaracer fire xc pros | | Bottom Line: | Durability. I have gone over glass and thorns on almost 1 out of every 2 rides I do. These tubes get punctured all the time, but that good sealant stuff works really well. Problem is that now, after several months of severe riding, all the sealant is gone!!! So now my front tire is flat. I used to be able to pump up a flat tire with these tubes and the sealant would have had enough time to seal, but since I'm outta sealant, I need another tube. Still, one of the best durability tubes out there. The only one that comes close to puncture resistance are slime tubes or the heavy ones. | Value Rating: Overall Rating: |

$8.00 | | Purchased At: | Specialized.com | | Strengths: | Seals your tires! Saves you money. | | Weaknesses: | Weight and it COULD seal faster. | | Bike Setup: | 2001 Stuntjumper M4, Judy SL fork, XTR guts, Mavic 517 rims | | Bottom Line: | I was tired of getting flats nearly every day, and since these got better reviews than slime tubes, I decided to give them a try. The first day I used them, I got a huge thorn in my tire, and the tube got somewhat flat. I stopped, took the thorn out, and let the sealant do it's work. I then pumped it full of air and WOW! It worked! There was a little balance problem after that due to the sealant gumming up in that one area, but after about 5 minutes of riding the problem was gone. Towards the end of the ride, I must've run through a thorn patch and got about 10 thorns in each tire :( I took them all out, and pumped it full of air, and it worked again! I rode them the second day (yesterday) and it went through the whole ride without losing any air at all. I'm extremely happy with these tubes, and they have already paid for themselves in that I don't have to buy tubes anymore. And another good thing is that I don't have to carry a damn bag on my seat for a spare tube anymore! I highly recommend these tubes to anyone who is tired of getting flats. | Value Rating: Overall Rating: |

Causes some wheel balance issues, but who cares. | | Similar Products Used: | Cheng Shin | | Bike Setup: | Bontranger Rims and Jones Tires | | Bottom Line: | I know that I've listed more weaknesses than actual strengths, but the biggest reason I love this tire is because it can stop a leak. I've had several tube punctures on the trail, but I haven't had one yet that this tube hasn't self sealed. The reason that I'm giving the tubes only four flamin' chilis is cause of its ability to gum up the stem (not all of the time, but it can happen); this can be irritating on the trail when trying to pump up a tube that has sprung a leak but sealed itself before going completely flat. I still recommend this tube however. | Value Rating: Overall Rating: |

Got a flat on a ride and found a huge hole in the tube. No problem, I pulled a new Airlock out and when I put a little air in the sealant came gushing out. It looked like a cum shot in a porn flick. I had sealant on my shorts, legs and, shoes. Well, after a 3 mile walk back to my car, I took it back to my LBS and they said "too bad" and I bought another one. Next day, out for a ride and on the second lap of a fun course, the new Airlock blew. Fortunately, the walk back to my car was much shorter this time but while I was walking back I decided to never to risk buying another Airlock.

$10.00 | | Purchased At: | LBS | | Strengths: | Peace of mind. The feeling that carrying a patch kit and a pump makes you overprepared. Major reduction in tire-based interruptions while riding. | | Weaknesses: | They are heavy and adversely affect wheel balance. No threading on the valve stem so they can not be locked in position on the rim. | | Similar Products Used: | Cheng Shin, Regular Specialized, Air-B (what a joke!) | | Bike Setup: | Ancient beater | | Bottom Line: | I would recommend these for anybody who does not enjoy patching/swapping tubes (have I left anybody out?) There are lighter tubes out there, and there are tubeless alternatives that may help with pinch flats, but I have yet to use a product that so completely eliminates one of the major time-wasting pain in the ass activities that so many cyclists have come to accept as a normal part of riding. Sure they are heavy, and even though the balance problem is noticable on the stand the only time it became noticable on the bike was above 40 mph. Riding around here in Stockholm in below-freezing temperatures has caused me to wonder about the freezing point of the sealant, but I have not had any pressure loss episodes, so this remains a mystery. After many years of trouble-free use I finally had a presta valve stick in the closed position on one of these. I can't find a Specialized distributor here, so I am trying out a Wrench Force self sealing tube as a replacement. I am fully prepared to be disappointed, the air-locks are a hard act to follow! | Value Rating: Overall Rating: |

Hold air for months even when full of wholes. | | Weaknesses: | Heavier weight than regular tubes about 100g per tube. | | Similar Products Used: | Generic latex tubes, ultra-light... can't remember them all. | | Bike Setup: | '92 Litespeed with Ti components, RockShox Indy. | | Bottom Line: | I first purchased these tubes after a friend and I were riding and hit the first patch of goathead thorns we had ever encountered in our lives. We both had 12 to 14 holes in each tube, our tires went flat at the same instant. The next day we went out and purchased Airlock tubes which in those days had a 6 month replacement guarantee. Immediately we rode to the same trail and rode through the same patch of goathead thorns. Nothing happened. Viva la Airlock tubes. Recently an Airlock tube with over 4 years of life in it gave up the ghost. When I took it out and examined it closely, there were more than 19 holes in it. 19 holes!! And even at that point I really only had to pump it up 10 lbs or so every 3 weeks. Better than a brand new regular tube. That's why I chose to use them on the new Santa Cruz Superlight I built up recently. Yes, it adds rolling resistance in the most critical part of the bike, but whenever I see those fields of star thistles before me, I can grin and charge ahead while my friends tremble and hold back. Small price to pay for peace of mind. However they WILL NOT seal a serious 1 inch long snake bite flat. That is too much. | Value Rating: Overall Rating: |

I used to get flats about once every three weeks, I haven't had one for over a year every since I purchased these tubes! Also pressure run-down has almost dissappeared. | | Weaknesses: | A bit heavy, and when new, they don't balance as well due to the amount of inner sealant. | | Similar Products Used: | Normal Tubes | | Bike Setup: | 2000 Gary Fisher Hardtail w/ lots of Bontrager. | | Bottom Line: | You cannot go wrong with these tubes. I only wish I had know of their existance sooner. Their moderately heavier weight is nothing compared to the piece of mind of using them(I stopped carrying the spare tube in my Camelbak). Also, as a side benefit, my tire pressure only goes down about 3 psi. a week, and that's with hard daily trail riding. | Value Rating: Overall Rating: |
