Iï¿½ve used Schwalbe tubes for reliable commuting, but the 60mm valve versions have hard to cone by. This tube from Continental seems to be a good substitute. So far the tubes I have installed have been reliable and hold air really well.
These tubes are heavier than the standard Michelin tubes I'd been using on my Jamis Supernova with Clement Xplor Ush tires, but they don't feel as heavy or 'weighty' as the Kenda Thornproofs I used for a while on my Miyata 610 with Gatorskins. The Kendas felt like they were partially filled with sand, but these Continentals roll just fine. Glad for the upgrade at a reasonable price. One star withheld because the tubes're new and who knows how they will hold up over time.
This tube works great for cross or adventure bikes with wide tires 32-42 mm. The tube is supple enough but it also thicker rubber than a road tube as it should be. I have been running these on 2 cross bikes and have not had any issues.
the tube itself is a little on the heavy side but considering I make it heavier by squirting an oz of stans in it i feel i shouldn't complain. being able to remove the valve core and add sealant was the my whole reason for getting this tube and it has held up well. no flats yet and that with running through a goat head patch.
The tube developed leak at the seam several miles into new ride. Checked the item, it has a leak at the seam where the radial and axial seams meet. Even though I realize that problems happen, this seems to be a design issue and might happen fairly often. I used the tune less than an hour. Is there any type of warranty? This is disappointing. I might go back to my old Tufo's.
I ride 50-75 miles a week. I have never had a problem with Conti's. I should have looked for a shorter Presta valve as the 60mm tends to be a bit out of balance. But at 72 years of age and my skill level 18 mph on hilly roads I never notice the wheels being out of balance. If I was a real racer I'm sure it would make a difference.
Conti generally makes tough products, if not always the lightest. This tube follows in that mold, as it's thicker than a regular tube, but I've also been able to get away with considerable abuse, running as low as 25 psi on some courses without damage.
It's difficult to get too excited about a bike tube but this tube is nicely constructed and has an extended threaded stem. It works perfectly with my fatty Gatorskins and I'm pretty confident the only time I'll see them again is when my tires wear out.
