Ok, so I'm familiar with the whole
Slowtwitch school of waterbottle placement.
My question, for the chattering classes of BikeForums, is this:
Given that the downtube on my TT bike is quite aero (06 Spec Transition), the logical place to put a waterbottle is the seat tube. Ok. Easy enough. I'm used to having a waterbottle there, as that's where it is on my road bike.
For the purposes of this discussion, we are ignoring a Profile Design bottle up front or behind-seat bottles.
However, would it be more aero to have an 'aero' waterbottle there (such as
Planet-X/
Profile/
Arundel,
Specialized,
Bontrager, et al.) or a regular one. The width of the regular one essentially shields the FD clamp and some of the seat stays. The 'aero' one is... well... 'aero.'
As I haven't got a wind tunnel in my garage, what are the thoughts of the masses?
Now I wonder about rigging up something to hold an 'aero' bottle such as those linked above right in front of the head tube, a la Profile bottles, but narrower...
