Maxxis Ultralight Presta Road Tube
Maxxis ultralight tubes are the standard in performance inner tubes for racing and training. Ultralight tubes are .6mm thin for weight consideration without loss of performance.
I have this on my front wheel, and it works great. Have put a little over 500 miles on this tube and I only reinflate 2x-3x a week (ride 5x a week). Its a little bit pricey, but hey, it's already paid for itself in terms of all the mileage put on it.
Running inside Maxxis Re-fuse tires. Tube is lightweight and cheap priced. Good pair for riding on LA's harsh streets!!
I've never had an issue with tubes and these are no exception. They work as expected. For me, I tend to like non-threaded tubes for ease of pumping, but for special events I like to use light-weight tubes. These delivered.
