I will ride my next Kilo on 27th with the new Pro Missile TT bars. Meanwhile here’s a quick comparison of the old 3T Aura and the new Pro Missile, and the reasoning why I did the change.
The biggest issue I had with the Aura was the lack of drop. In the start I compensated the too high bullhorn by pulling and bending my arms, which in turn created a full list of other issues. In short I was wasting energy and power and therefore lacking acceleration and top speed. Ok, so why do I believe I’m better off with Pro? Let’s take a look at another picture.
It does not get any clearer than this. Bullhorns of the Pro have about 65mm drop, Aura has none. The height of the arm pads in Aura is pretty easy to change with the spacer kit. Pro does not have that kind of flexibility, but then the question is should it? I used the spacer kit to get comfy, and that obviously also meant less aero. So, as in any case I need to get lower in the TT position, it does not matter much which bar I have. But for the first 200m I need to get lower. And this was the only way to do it.
There’s plenty of stems with different angles, that give a bit extra wiggle room in the setup. (As a side note: If you’re interested in how different stem lengths and angles change your setup check out the Habanero’s site on the subject.) I run the Aura bar with a 110mm stem, but the Pro’s horns are more forward so I need to shorten the stem a bit. A 90mm stem with 6 deg angle should do the job just fine.
July 26th will tell if and how the Pro Missile changed things for me.
