I am trying to decide on the best drink system for an Ironman.
To my mind you have a number choices all of which claim to save time which is equally nearly always disputed by one person or another. The systems are:
1. Standard twin bottles on a frame tube, claimed to save you time with a round tubed bike, but to cost time with an aero tubed bike. (What about the old Campag aero bottles? If I were Campy I would reintroduce them to fit a standard cage and sponsor an Ironman event! It wouldn't take long for everybody to start using them).
2. Bottles behind the seat, claimed to save time especially if low down, disputed and quoted as costing 3 mins in drag (aside from reaching or the bottle!) over 112 miles.
3. Front mounted systems, some say they are fast some say they are slow especially due to the drag from the straw. I seem to remember a profile front mounted drink system being banned, was it due to an unfair aero advantage?
4. Camel back, very fast due to aero shape but to hard to fill on the fly and too heavy to carry all you require for 5 hours of cycling.
5. Concealed systems, such as in the CAT bikes with an internal bladder, and that straw again.
6. Never reach systems, reported as saving two minutes over an Ironman, but damn ugly.
The ideal system may not even exist I am just interested to hear your points of view.
