I bought the Continental 1.752.5 MTB 26 tubes with the Presta valves to install with my Michelin Country Rock 26 1.75 tires that I bought at WesternBikeWorks. I store my bike in my home, but I haven't had to add air in the tires for 3 weeks and the pressure is still the same. With my old tubes, I had to add air weekly. These tubes have exceeded my expectations. Will buy again!
I had been running Slime in all my bike tires for over 6 yrs, recently had a flat and changing the flat, there was al this watery green fluid (Exhausted Slime) Slime has a useful life of 2 yrs, had to change all my tubes, since all have 6 yr old Slime. Outside of that one flat never had a problem with Continental tubes - knock on wood

Can't really review the tubes other than to say I received one that was defective and Western Bikeworks sent a new tube out right away. Excellent customer service. Looking forward to doing business again. Suspect that the tubes will work great. 5 stars for the bike shop....and if I don't edit the review at a later time, assume 5 stars for the tubes also.
The Continental TourMTB 26 Tube has been amazing. Has held air for months now and no need to pump them up again. I have been storing my bike in my home so I'm sure that helps, but my old tubes required refill after a week. These tubes are much better. I've been riding on pavement and on gravel roads and no punctures or problems.
These tubes are made very well and I have not had any issues with them unlike other brands. It is really handy they come with a small nut to screw down around the value stem to help it in place. It is a big help when trying to inflate a tire.
These are quality inexpensive tubes. The valve stem is threaded all the way to the base and there is a nut that goes over the threads. This gives you the ability to secure the valve stem in place making installation incredibly easy.
