Tacx, Shanti, Bottle, 750ml, Fluo Yellow

I like large bottles on the bike, whether it is a single or tandem. For years I used Zephal Magnum 32oz bottles. They have a gasket and did not leak. Now they are out of production, but the gasket eventually breaks down, and even if the gasket does not lose its integrity, the water nozzle, after being pushed up and down for thousands of drinks, begins to leak. The Tacx is only 750ml, but its unique mechanism has been leakproof. When the top is twisted, nothing comes out. Untwist it, put it in a bottle cage, and you just squeeze to drink, with no leakage. What a relief to not to have to clean that sticky residue off after each ride.
