Anyone have any feedback regarding the fit?

Only the tubular got wider. The 19mm matches up very tight on the front of the 808 clincher. Jonnyo used to run that setup. It's slick. You *are* running a 19mm tire up front, which I personally would not want to do for an Ironman. That's just a very narrow tire.

After looking at the new Crr data over the weekend, the new Bonty R4 Aero (?) is 22 mm wide, which will probably be my preference if I can get ahold of one before June, but the 19mm Aero TT is/was my back-up plan.

Do you think the 21mm Zipp Tangente is a better option for the front? I assume you say you would not want one due to the ride quality, right? For what it's worth, I am planning on the Specialized S-Work Open Mondo 23mm for the rear.

i was running a 23mm...not a 19... and would not change a thing... 23 all the way, i simply dont care about any lose in aerodynamic for the gain i have in comfort and i simply feel lot better on the wider tire..

i also ran the 21 and it was good but not as nice as the 23....

Yes, for ride quality. I've run a 21 in the front (and ran on in Abu Dhabi) without issue. You just need more psi (I run 125-130 in the front if I run a 21). With all the weight on the front in a TT position, a 19mm tire for Ironman is just a bad idea, IMO.

Interesting point. Since I weight more than you (currently 170 lbs, hopefully 165 at race time) I would need similar it no more pressure, so it sounds like at least a 21, but would a 23 be better? What do you think about the Zipp as a front (21 or 23), or the Specialized Open Mondo (23)?

Thanks for your feedback.

I've used the Zipp tires with good success. I've not used the Mondo, but I think it's also a very good tire. The Zipp *should* have better aerodynamics, but I'm not sure by how much. I doubt you could go wrong with either one.
