Not much to say, it is a bicycle tube. It is not puncture proof and won't prevent a pinch flat if you don't install it properly. All that being said, it is a very good tube and a good value for the money. I carry an extra one and when I get a flat I check to make sure what caused it is still not in the tire, put the new tube in, inflate it and continue with my ride. I have NEVER had a problem with one of these that was quality related so that's a big plus to me.
ride six days a week, near the 10k club in annual miles. predominate three bike selection with competitive fit profile. Increasing interest in occasional gravel routes.
air loss is about 3% per day
longer stems, (48mm), unless gently handled on air fill, have more valve problems (bend or break)
more problems, minor presta valve bendingoccasional break, with 23 verse 2528 tubes. Why?
flat occurrence is minimal for initial 2.7k - 3k miles. Buy on deal and just change the tubes out.
flats consistent across several tire brands, though tubes with my Michelin 25c tires are flatting more
Pleasantly very surprised, but after new Pro4 Endurance on the back and Power tires on the front, and using these tubes, I haven't had my usual flat every 2-3 weeks. These have changed my mind about all tubes being the same. Apparently not. Very impressed.
Conti's products are fabulous, so of course I was going to get their tubes. I was shopping around and then found that my local Western had the best prices. I bought extras and I haven't had a blowout in a while, but when I do I'll be prepared!!
These Conti inner tubes are as reliable as any brand and are available in 60mm stem length. Not all 60mm stems are as long as these. For instance, I bought a 60mm OTC Bontrager inner tube at my LBS, but the stem was too short for my 52mm rim height wheels. So I was unable to get a tire pump on the stem to pump up the tire. Additionally, I am happy that the Conti has a removable core, which allows it to be removed and inserted in a stem extender. The Conti inner tubes seem to hold air well and need very little topping off after two days. But, they will flat just like any other inner tube.
