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.
What can you say about a tube, it's light, worked great. Keep it as a lightweight spare carried on my bike.
This is my third tube and won't be my last. These tubes are very light and fairly puncture resistant. The presta valves are built well and fixed to the tube better than other brands. I've always had issues with valves splitting from the tubes with other brands but as usual Maxxis performs. Great product and great price, thanks Pricepoint!
