The Gear West Aero Bottle: How-to

So to give you a little backround on the ‘Gear West Aero Bottle’, it all starts appx. 4 years ago with the Vision Drinkmore cage (pictured below)
VISION-DRINKMORE

The cage fit between your aerobars, with a normal water bottle fitting in horizontally between your arms.   It was a great concept, as you could get a normal water bottle within inches of your hands and mouth.  Making it very easy to grab and use, as well as making it ideal for bottle exchange stations in races.  (As an aside, David Thompson actually claims that he came up with a crude version of this in 2002 for the Pigman Half Ironman which involved a couple rubber bands, but I digress…)  When Gear West Bike and Tri went to the MIT wind tunnel in 2007 and 2008, we tested this bottle configuration compared to a traditional aerobottle (Profile Aerodrink), as well as many other hydration configurations and this came out on top, causing ZERO additional drag (David actually thinks it slightly improves aerodynamics, fostering a smoother airflow).   Gear West Bike and Tri spread the word fast and in 2007 and 2008 you could find many of the GW athletes and customers coming out to races with these on their bikes.  There was one problem with the Vision Drinkmore, they ejected bottles worse than any cage I’ve ever seen (I had a personal bottle eject rate of appx. 50%).  Not good when you’re depending on the hydration in long races. 

That brings us to the Gear West Aero Bottle.  Kevin and David came up with the idea of mounting a side entry cage in the same configuration as the Drinkmore cage, thus providing the same aero-benefit (Zero drag), but giving the bottle much more ejection prevention.   

Here’s how you can make your own:

Materials needed: 
Side Entry Cage (carbon $50 -$60 or aluminum $15)
Old bike tube or tubular tire (free)
Electrical tape ($3 a roll)
4 zip ties (free if you ask us nicely)
Total cost: $18-$78

Step 1.  Position the cage in between the aerobars open-end up so that the bottom of the cage is as close to your stem as possible and visually take note on the bars where you will need to position the ‘tube-wrap’.  
Step 2.  Cut the tube or tubular tire down to 2 strips, each 6-8 inches in length and wrap them around the bar in the 2 areas you visually marked, wrapping it with electrical tape to keep them solidly in place.   The amount of wrapping you put on the bar will depend on how much space you ahve between your aerobars (see image below) 
Step 3.  Put the cage in place and use the 4 zip ties to secure the cage to the bars at the four corners of the cage.

Boom.  No bottle ejection, zero drag, easy to stay hydrated.

  1. Great idea. I have the Vision setup already, once I was shown the idea with the rubberbands on the end, I think David told me about it, I stopped having the bottle ejection issue. All have to do is remember to keep fresh rubberbands around

  2. Instead of electrical tape you should try the teflon tape, it is waterproof and seals upon it self, we use it to keep water out of electircal connections outside, works great!
