Question: TT bar angle impact on front hydration system
Quote | Reply
Question:
Anyone running a 15 degree TT bar angle? If so, what are you using or recommend for between-the-arm front hydration system?

Doing a lot of indoor Zwifting, and realized without the outdoor stimulus how tense my upper body gets while in aero. I got professionally fitted for my Cervelo P3X when I first purchased the bike, and the TT bars were set at 10 degrees. After watching the GTN episode on “What is the Best TT Bar Angle for Cycling?”, I decided to try 15 degrees, which Silverstone Sports Engineering recommended was best for most riders.

I am finding that 15 degrees is MUCH more comfortable for me, and allows my upper body to be more relaxed while in aero. But the consequence is that due to the angle, my front hydration systems (XLab torpedo and Profile Design FC) can only be filled to about half the capacity they are intended to carry—solution leaks out of the fill port due to the tilt, and becomes more pronounced with sloshing. And it is difficult to gauge exactly when to stop filling while on the road—even a slight miscalculation in filling the tilted setup results in drizzling of rust-causing electrolyte-laden solution all over my cockpit while riding over small bumps.

Anyone else having this problem? 15 degrees TT bar angle has got to be pretty common, and the designers of front hydration systems seemed to assume near-level TT bars for everyone. Last resort for me is to go to a simple between the arm bottle, but I really like to sip on a straw while in aero. Any suggestions?

Profile Design working on solutions for this. An adaptor specific to certain PD products will be out next year as a running change (no, I don't know when). Making a universal adaptor that isn't priced excessively high is proving to be a challenge.

I discussed the same issue in this post.

Vision DS1 bottle all the way made for anged bars with the fill point at the top.

One option might be the Speedfil A2 in a BTA cage: https://www.amazon.com/...2155566381&psc=1

The filling port is up near the top end of the bottle, the bottle is clear so you can easily see the fill level, and you can swap it out for a regular BTA bottle if you choose to. The main drawback is it is a bit of a dated system.
