So I'm heading interstate for a four-stage race in mid April, the first stage of which is a less than flat TT:
The course is completely non-technical - no corners and it's a straight shot, so no turnaround.
I've been thinking about this for a while, but can't decide on whether to use the TT bike or the road bike for the course. The TT bike would obviously be a bit of a pain on the uphill section, but do you think the gain in speed on the downhill section would mean the TT bike would be faster overall?

I'm wrestling with a similar question, but the uphill isn't nearly as long, and is more steep.
For 2.4% that stays a reasonably constant grade, I'd probably go with the TT bike.
I would think you'd be able to stay in the aerobars for 2.4% shouldn't you? That, coupled with the downhill and non-technical, would lead me to use the TT bike.

I was watching highlights from some Australian Tour from last year on WCSN, and they had something similar to this problem. 99% of the guys rode their normal road bikes with clip on areo bars and a disc wheel.

I'm thinking clip on aero bars.

Full on TT bike.
2.4% grade for 7k is no big deal and the incline is shallow enough that the speeds should be high enough for you to get gains from all the TT gear no matter the length of the climb.

Unless your power output is going to be around 150 watts, TT bike the whole way.

As long as the decent isn't at all narly and you're not like me (I can't descend to save my life on a TT bike), then +1 to TT bike.
If it was the uphill alone, the TT bike for sure would be faster.
More marketing than science, but it gets the point across:

TT bike, no question

Awesome, thanks guys :)
FWIW, I'll be putting out around 375W over the course of the TT, so I think you're right about 2.4% not being too much of a big deal.
