Contemporary version of the old Campy Aero bottle and cage. Great piece for your TT bike.
Good areo design but the bottle will not stay in the cage even on smooth pavement. Would not recommend it.
Mine ejected the bottle while riding over a frost heave on the state championship time trial course. I'm considering adding velcro to the cage and bottle.
Pros: Low aero profile
Cons: Ejector bottle!
Why buy an aero bottle? That would be to cut wind resistance when racing. When you race you want to swallow as much liquid as you can then return your bottle. Every time I use this bottle it frustrates the hell out of me because of the terrible flow rate. It takes forever to empty this bottle and a minute or two just to get a good gulp.This is one of the worst designs of a bottles cap I have ever used. It does fit well in the cage and is easy to remove and replace. If you want an aero bottle get a Specialized aero bottle and leave this junk on the shelf.
Great system. So why carry two on the frame? The second bottle fits perfectly in a jersey pocket. I freeze mine before the ride and then swap them out when I empty the one on the frame....and my core stay cooler, just a little longer.
Cage and bottle are solid and well constructed.
Cons: The flow rate through the nozzle is not great. You have to suck and squeeze the bottle to get flow. It can be tricky to get the bottle back into the cage without looking it in which is time away from looking forward.
Pluses: A gripply surface, a pretty watertight cap and a translucent bottle so you can see the fluid level. The flow rate is likely only an issue in a race but thats why Im looking at alternatives.
Great product but if you have a small frame you can only fit one on and it becomes pointless unless you ride less than 20 miles or cooler weather. It does make the frame more aero though. Great for a down tube of a time trial bike where you have two bottles behind the seat and this one on the frame.
Cheapest way to make your bike faster. Years ago when Shimano introduced an aero gruppo, their wind tunnel tests said that the aero water bottle made more of a difference than all the other aero components combined -- and was the cheapest item. My only complaint is that I can only fit one water bottle on the bike, instead of two round bottles.
