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.
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!
