Perfect fit. Comes with instructions. Lasts a long time. Took about 20 minutes to remove old inner tube and get back on the road with beginners experience.

I have bought 4 of these tubes this summer and found that three of them had valve stem separation at low millage. I'm tired of walking my bike more than riding it. Definitely have some product quality issues!!Brontrager 26 x 1.75-2.125Part# 230622210811

Literally have gone through 5 tubes in a month. Each tube either failed at the valve stem or the seam. Verified tube was correctly installed and nothing in tire or rim that would cause a flat. While putting the flat tubes under water, can visually see leaks at seam and at valve stem area. These tubes are expensive and of poor quality. No quality control at all. Will not buy bontrager tubes again.

Went through three tubes in three weeks. Two of the tubes had valve stem issues. The third one had a thin wall. No puncture. I think it was a blemish.
Theses are great lightweight tubes. Not as light as some other brands but not far off. I've had more punctures with these tubes than with the heavier ones but no more than other lightweight tubes. If you are looking to save some rotational weight and don't mind the added risk of flats, these are for you.
I have a Madone SL7 and plenty of Bontrager components, all of which I love. Unfortunately I cannot say the same for these tubes. In years of cycling they are the worst I've used and are among the most expensive butyl tubes I have ever purchased. The first point of frustration is with the valve itself. The rubber stopper at the bottom of the valve core is so finicky that unless I really cranked down on the valve the tube would slowly release air. With every other brand I've owned the air pressure itself was enough to close the valve again. Valve issues aside, after less than 400 miles of riding on my standard weeknight route and I had a blowout. I didn't hit a pothole, and there was no debris - the tire itself was not compromised in any way. I was running the tube ... MoreI have a Madone SL7 and plenty of Bontrager components, all of which I love. Unfortunately I cannot say the same for these tubes.

I didn't hit a pothole, and there was no debris - the tire itself was not compromised in any way. I was running the tube at 70 PSI in a 28 mm tire, so pressure was not an issue. I'll be sticking with my Q-Tubes for now, which have proven to be far more durable for half the price.
Problems with removable stems. If they are not tight, they leak. Worse is the stem can come out and stick in a CO2 type filler. Nearly impossible to fix the filler on the road. Plan on having spare tubes plus alternate way of filling OR walking home. One stem came out just talking off the cap. Removed the stem on the other seven with my fingers. Put lock-tight on the threads and reassemble firmly. Appears to be the new normal on bicycle tubes.
The tube was the proper size for what I needed, but I didn't use it. I was a bicycle escort for the Disabled Division of the Detroit Free Press Marathon. We were asked to have both a 650 and 700 tube with us if our rider got a flat on the course. We didn't need the tube.
Bontrager box, kenda tube inside.I purchased two bontrager tubes from rei only to get home and discover one of the boxes contained a cheap kenda tube with a short valve stem.I opened the other box to double check, and that one contained a bontrager tube with 60mm valve stem inside.
Fits well and is easy to get onto the rim. Puncture protection is better than I expected, going over many thorns.
