MEETLOCKS Bike Tube MTB 26x1.75-2.125 Recycle Butyl Solid Brass Stem Valve Presta,2 Pcs Pack,4 Pcs Pack for Choice

I don't know what a 'Meet Locks' is, but these tubes are very, very good! Heavier than the ones from the bike shop, these have given me much more confidence in their ability to reduce flats. My relatively short commute on city streets and bridges is a mine-field of splattered pebbles, glass, metal shards and other debris. Previously... three flats in two weeks. Subsequently... none in well over a month. Highly Recommended... especially if I can limit future flats to one-a-month or less.Update 11/11/15: Front tube finally failed at the presta stem's base while doing a routine inflation. That's ten months [800 miles] of commuting without any tube-related issues. Meet Locks easily retains their five-star rating.

I installed one of these tubes on my mountain bike a few days ago and have put about 40 miles on it, so I can't say much about long term use. The tube is a bit heavier than the typical tube, I think that is a good thing. The valve stem appears to be connected to the tube much better than the tube I replaced. Recently I have had three tubes fail at the valve stem and so was looking for a better built tube. Love the bright green caps - easy to find.

These tubes have been in use for over six months. They come in a plain rap box but are a solid quality value. No slime or slick stuff jamming up your fill valve (and yes I did have the valves upright, shaken, and waited a few minutes before filling those Slime things). These are basic inner tubes and I will buy again when needed.My bike uses presta valves and the liquid filled tubes did not work for me. These work excellent and hold air very well, better than tubes I have used in the past. My mountain bike is ten years old and still rockin'.May God Bless. Hope this review helps.

Been mountain biking on these at lower pressures (30-35psi) for a while now and have had zero issues. Seem to leak slower than my more expensive tubes actually.

The first tube I received blew up very unevenly with a giant bulge in one part of the tube to the point where it wouldn't fit into my tire, so I had to buy another one. I didn't contact the manufacturer, because they were cheap enough that I didn't care about the cost, so I can't speak to how they would have handled it. The rest of the tubes worked very well.

I installed one tube on the rear wheel of my bike and inflated it up to the recommended pressure. The next day the tube had already blown out. Poor quality.

Put the 1.75-2.125 presta in a 1.95 tire. I've got a decent ride to get to the trail so I like to inflate to a high psi. Pumping this up til I can't pump anymore still leaves the tire soft. Fine on the trail but I'd prefer higher volume for the street. Wouldn't recommend for commuting or with high volume tires.

these tubes are quality and have had no problems with the valves. I like that they come with a locking nut to fit snug on the rim for better control while airing up.

Ordered a pair and one of them is fine so far, however the other one developed a leak at the stem. This is after a total of less than two hours of total ride time. Have emailed the company and received a replacement in the same week.

Ich habe den Presta 40 mm (26", 1.75-2.15) Schlauch für mein Mountainbike bestellt. Er war wohl der billigste, was ich gefunden habe. Einfach und gut verpackt, kam pünktlich und schnell an (Prime zu danken). 40 mm passt perfekt für die low profile Felge - Ventil ist nicht zu lang. Über Haltbarkeit kann ich erst nichts sagen, werde die Rezension aktualisieren, wenn was zu berichten ist. Momentan kann nur weiterempfehlen!

Genau wie beschrieben. Schlauch passt für mein Mountainbike. Wirkt robust und hoffe, dass der Schlauch auch lange hält. Im Moment ist er seit 4 Wochen in gebrauch ohne Probleme. Schlauch kommt gut verpackt an. Keine Beschädigungen und auch kein verkleben.

Kann mich den anderen Rezensionen nicht anschließen. Ich weiß nicht ob mein gelieferter Schlauch eine Ausnahme war, aber ich habe selten einen so schlechten Fahrradschlauch erlebt. In aufgeblasenem Zustand hat er unterschiedliche Durchmesser über die gesamte Länge, als ob man ein paar Reststücke zusammengefügt hätte. Werde ich jedenfalls nicht mehr kaufen.

I always have a few on inventory so as to always have them in stock .. So far thèse work very well .. Good qualité .. Recommend+++

Description clear as mud. Probably written by a foreigner. Or they just want to sell something you don't want.

good product, good price. I would shop here again.

it is the first time I bought it, but it is very good inner tube, nice package and cheaper than market

Tube sprang a huge leak right at the valve after two rides.

Funzionano bene su una ruota 26'' x 2.10, la valvola è abbastanza lunga ed è di tipo Presta. La consiglio
