Schwalbe(シュワルベ) 【正規品】 26×1.50/2.50用チューブ 仏式 40㎜バルブ 13SV

I commute to work 22 miles by bicycle, ride a tandem with my wife on the weekends, go cycle touring, and try to do everything else by bicycle also. Because of this I have several different bikes and some of my bikes even have more than one wheel set so I need a lot of tubes and tires. My wife wanted to ride her mountain bike in comfort on paved and hard packed trails so I purchased these 40mm Presta/French (26 x 1.5-2.5 - 40mm Presta - SV13) Schwalbe bicycle tubes so I wouldn't have to pump her tires before every ride anymore and I installed them in a pair of Schwalbe Marathon Supreme tires Schwalbe Marathon Supreme HS 382 Touring Road Bike Tire (26x2.0, Triple Nano Triple Nano Folding, Reflex) so I wouldn't have to repair any flat tires. I also had to buy a pair of Stem Savers VALVE STEM SAVER WOB ALY 1pr so I could use these Presta tubes in her old Schrader rims and now I only need to have one style of pump for all of our tires and Presta valves are said to leak less air than Schrader valves. I can now go about 2 or 3 times longer between pumping up her tires than I could with the cheap tubes that she was using before. Schwalbe tubes hold air pressure better than any other tube that I have tried. I have tried a lot of different tube brands and I have tried almost every brand of tube that fits a 700x37 tire because that is what I run on both my tandem, touring, and commuter bikes, and I used to get a lot of flats because of where I rode and the tires I was using. I also went through a lot of tubes simply because I always replace the tubes instead of patching just for safety because I love high speed descents. I decided to try Schwalbe tubes after reading reviews that they hold air better than other brands and I have been very pleased with their performance in that category. I can easily go several weeks without pumping up the tires on my commuter bike but I do give the tires a test squeeze before each ride. I love the tubes instruction sheet where it shows that you should pump your tires once every 30 days. I have actually gone 30 days without pumping my commuter bike's tires (I call it the 30 day challenge and I did it just to earn the badge of honor) and the tires were noticeably softer but still rideable after an entire month during which I rode about 24 days of pump free riding. Wow!I can not comment on their flat resistance because I had just switched most of my bikes tires to Schwalbe Marathon Supreme tires before I switched to Schwalbe tubes and have not had a single flat since switching to the Schwalbe tires about 3 years ago. I admit that I am very lazy when it comes to tire repair. While my friends ride lighter tires and tubes so that they can ride faster, ironically they never leave me behind, they mostly just stay in practice and constantly improve their flat repairing speed and skills. I would rather ride on slightly heavier tubes and tires in order to avoid repairing flats.Do you really want to pump your tires before every ride? Do you really want to repair a flat in the rain, snow, sleet, hail, or blazing summer sun? Then put Schwalbe tubes in a pair of Schwalbe Marathon Supreme tires and you will no longer pump your tires before every ride nor will you have to stop to repair flats anymore.

These tubes work well and hold air as well as any bike tube I have purchased.

This brand has worked well in the past.

Fit is exact, True-To-Size ... Presta Valve plenty long, easy to access for inputting air ... Tread is as expected .... Rides nice, no issues .... Recommend.

Good tube with presta valve.

Built a DJ bike, decided to run some Schwalbe Table Tops, and figured I’d throw some matching Schwalbe tubes in there. Not too concerned about saving the weight and running tubeless, bc I never run low pressures on tracks. Presta valve stems look a bit long, so I may look for shorter ones in the future. So far, tubes are holding up to all my shenanigans.

I've used another brand that, inexplicably, seemed delicate compared to the resilience of these. These, however, seem tough. The last thing you want is to be in the middle of nowhere with a flat tire, and your one and only spare keeps springing new holes, even after patching it. Not only are tubes susceptible to obvious road hazards, but you could very well damage them while they are in storage, or even while installing the spare (by getting them caught in the rim, for example).

I bought 4 SCHWALBE Bicycle Tubes with 40mm Presta Valve, 26 x 1.5-2.5-Inch.One of the four went flat overnight due to a poor vulcanization weld -- where the small oval of rubber around the valve stem is attached to the tube. It was a pretty obvious leak so it looks like quality control is limited. Make sure to check out your tubes before the 30 day return policy is over.

Wie gewohnt gute Qualität von Schwalbe. Gerne wieder.
