I use these bottles on my road bike and gravel bike. If you have used the previous Podium bottle, it's easier to just tell you what's different. A big plus is the new nozzle. It's higher volume and works great. It takes more effort to move the nozzle from the locked to the open position, but that's a minor inconvenience. The other change CAN be a problem. This Podium is slightly smaller in diameter than the old Podium. The old Podium fit snugly within my carbon bottle cages - sometimes a bit too snug. I sometimes had to wrestle it out of the cage, but at least I never ever had to worry about it bouncing out. The new Podium is very easy to get in and out of the cage, but it can be susceptible to bouncing out if you hit very large sharp-edged bumps.
I've had a couple of the previous versions of the podium bottle. For my purposes this one is the best so far. It's softermore supple and fluids flow from the valve more smoothly. However, the updated locking closure is less refined as it is stiffer and less ergonomic (sharper edges and less surface area), making it more difficult to open while ridingI make sure I open it before I'm riding seriously. FYI the black is glossy the pic makes it look like a matte or satin finish.
