These are nice tubes. Heavier than what I would consider racing tubes but I'm not a racer just a casual rider wanting durability and not necessarily light weight. I like the length of the valve stems. Perfect tube for me and will be ordering more for the future.
I trust this tube to do its job more than competing ones. The valve stem is top notch and holds pressure longer than others. I like the removable valve core so I can use a valve extender. You can expect to pay a dollar more per tube than for competitor's tubes. And 60mm valve stem length is fully that. A competitor's 60mm did not extend through my 52mm rims enough to get a pump head on it.
These tubes always prove to be reliable and lightweight. I would recommend something thickerheftier for rough roads or serious commuting, but that's only because that use isn't really what these tubes are intended for.
I used to buy the cheapest tubes but after buying these a few years ago I never looked back. For my type of road riding (back country road), they hold up better than what I used in the past. I highly recommend these tubes over others.
I purchased the long stem tubes. The tubes are high quality and fit well into the well of the tire. The valve insert will come out if your pump grips it as mine did. I finally put an adapter on the valve stem and that seemed to do the trick - not ideal if you have to change a flat on the side of the road.
