The 2-person Triumph Deck Rider Towable Tube is built for speed and occasional flight off the wake! The low-profile design of these deck tubes makes them easy to board, while the soft EVA foam body pads provide a comfortable nonchafing ride. Double-webbing foam handles with neoprene knuckle pads are extremely easy to hold. Lightning valve inflates/deflates 57% faster than standard Boston valve. 340-lb. weight capacity. 70" diameter. One-year warranty. The Lightning Valve is similar to the Boston Valve except that it is attached to the towable, so there are no parts to keep up with or lose. The wider opening inflates and deflates 57% faster than the Boston Valve. An interior flap prevents air from escaping, even if the cap is not in place. Inside diameter of the valve measures 30mm. Overton’s recommends purchasing one of our Inflator/Deflator pumps (items #109694, #109532, or #109572) that come with an adapter sized to fit the new Lightning valve.
