Inviscid Design Speedfil hydration system gear reviews

My wife has been looking for this for her 48" P3 after seeing this on another bike at a local race. I have purchased enough junky upgrades in the that don't add any speed or comfort and end up in my junk closet. I wanted to see this in person so I wouldn't add more stuff to the closet. I found the booth at the Chicago Expo and the guys there offered to install the bottles at a discount. I ended up getting 2, one for my wife and one for me. We used them in the triathlon and they worked great. I blew my rear tire 6 mile into the bike ride but based on my own recording I was headed for a PR. The bottles have been great on 3+ hour rides and are easy to refill on the fly.

This is a must-have product if you race and have ever fumbled with water bottles - or skipped drinking because of the bother. I stay MUCH better hydrated during races with Speedfil.
