Avenir Thorn Resistant Tube 700x18-25c Review

Average Reviews:

(More customer reviews)These are heavy duty tubes. I did not expect them to be as thick as they are and I mean they are thick. I installed these tubes on two of my bikes so far but haven't had a chance to go for a long ride yet. But I didn't have any problems with installation. I removed the original tubes and installed these and I used one of the ORIGINAL tubes as a spare in case I do have a flat. I would not use one of these as a spare as they are about the weight of three regular tubes combined.

I have a Burley trailer that uses 20x1.75 tubes and even ordered tubes for it as I don't want any flats. And even if I do these are so thick that I could probably run the tires flat and still keep going.
I was leary about ordering these at first but at this time I am very please with this product. Just take your time and make sure that the tire seats itself properly on the rim and I would recommend these to others and I will also update my review of them after I get some miles on these tubes.
Since these tubes are so thick and heavy it might take some more effort to pedal because of the rotational force that is involved. I don't think I would use these on my road bike because of that. But for the commuter bike that I plan on riding to work (7 miles one way) or the bike for pulling by trailer it won't matter that much to me. I don't want to fix a flat. If you are planning on riding a long distance (10 to 20 miles or more) stay with the lighter tubes and just carry a spare tube in case you have a flat. It will take more effort to pedal but you won't be fixing flats all the time.UPDATE....I had these for five months and the problem that I have had was that the brass is not sealed to the rubber as it should and the air is leaking out around it. I don't know of anyway to seal this so the tube is trashed. This is the first time that I have had any problems with the filler valves messing up.

Schwinn SelfSeal Tube (27-Inch x 1.25) Review

Average Reviews:

(More customer reviews)A self-sealing tube sounds like a good idea, but the blue goop inside the tube only protects the part of the tube behind the tire tread, I think because of centrifugal force. So any thorn or other hazard hitting the sidewall is not protected against. This in itself is not bad since without a sealant there would be no protection. Second, I try to balance my bike wheels, but the goop inside seems to flow inside the tube so that the tire might be in balance in one position and out in another. Third, When riding, I sense the wheel wobbling and theorize it may be the goop inside. (Getting regular tubes helped this.) Fourth, if air seeps out of the valve stem--as it may when you remove the tire pump fitting, the goop flows back through the valve core and seals the valve. When I finally decided I had had it with the tubes, the only way I could get the air out of one so I could remove the tire was to break off the stem. When I removed the valve core from the other tube, the air came out so I could remove the wheel. Then I squeezed at least an eighth of a cup of blue goop out. My new tubes are basic model at under $4. Easy to fill with air, and I carry a patch kit which you need anyway.

Slime Smart Tube Schrader Valve Bicycle Tube (24 x 1.75-2.125) Review

Average Reviews:

(More customer reviews)The Slime tube sealant, i.e. the green goop that comes in bottles, works. These slime tires are a gimmick; they only succeed in making a mess.
I replaced 3 old flat bike tubes with these slime tubes, and each and every one was flat within a month.
I should be more specific: These tubes are okay for a street bike because there is very little debri on a street capable of puncturing a tire, thus the slime never sees the light of day. For a mountain bike these things are a disaster. Actually, they go flat more readily than a normal tire tube, likely because the tubes themselves are cheaply made.Road bikes should find these tubes 'suitable', barely, and only because they don't encounter punctures as often. I don't recommend them. Get a bottle of the Slime sealant and pair that with a strong, well made tube.

Avenir Thorn-Resistant Schrader Valve Tube (24 x 1.95-2.125) Review

Average Reviews:

(More customer reviews)Have always had problems with my sons bike tires holding air. I replaced his tubes with these because they are thicker walled and should in theory slow down air loss. So far, so good. Been about a month now since initially airing them up and the tires feel almost as firm as they did at the beginning. I checked the old tubes for air leaks and they didn't have any, they just would not hold air pressure adequately and
had to be aired up often.

Mr. Tuffy Bicycle Tire Liner Review

Average Reviews:

(More customer reviews)I live in New Mexico and we have some nasty thorns on our trails. So far the Tuffy's alone have kept me from constantly repairing inner-tubes. I highly recommend.
UPDATE (May 28, 2009): 40+ Hours of trail time and not a single flat. I have also put these in my wife's tires too. Great investment for those who are willing to sacrifice a little bit of extra weight for more ride time and overall enjoyment. A little bit of advice on installation, I used some Permatex weatherstripping adhesive to hold the liner in the tire for easier installation.

Michelin Airstop C2 Butyl MTB Bike Tube ((26 x 1.1/1.5) Review

Average Reviews:

(More customer reviews)I tried the Avenir tube with nothing but nightmare results. This tube it the best on I have found of this type. I biked almost 6,000 miles in rural Maine last year. Flats are such a hassle in the middle of nowhere, especially in the bad weather or winter. Avenir tubes have stem problems, these don't. What a differnce that can make on a distance ride.

I have never had flat tire on the back tire since then; while I had to patch my front tube two times.
I am going to buy another one for my front tire.
WARNING:: If you relieve the air from the tube, beware that the green slime may leak out with the air.
