True. Mine is a standard double 39/25. Yes, it's a bear at 19-21%, but I can still get it to go.
Most people around here setup their TT bikes with compact cranks, and honestly, even though I'm no slouch on the bike, I'd be fine with a compact crank as well even on a flat course. It's not like I'm pushing 300+ average watts for my races.

PS: jmX, you say you add aerobars for certain days to your Roubaix. Do you remove them for other days? Do you leave the mounting clamps in place? Curious what your practice is.
Lastly, what kind of handlebar do you have on your 56 Roubaix that allows attachment of a clip on aerobar? If I want to try this as an experiment I would have to change out my FSA Kwing handlebar which will not accept a clip on due to the bulbous flat shape of the bar near the stem. Thanks

I use a standard road bar...Ritchey superlogic II I think, which specifically states it works with clip-ons.
A pic of the endurance setup on the 56.5cm Roubaix - pre-Di2 (from an odd angle, sorry)
And one of the TT position on the much less attractive Shiv (water stored in the downtube, as well as between the aerobars):

Beautiful bikes jmX and thanks for the review. We are likely the same size. Quite a long seat post on your 56 Roubaix which btw is quite a steed...very nice bike and congrats on owning it.
Looks like you have a Thomson setback post on the bike which have a very modest 16mm setback so a good candidate to work with aero bars. Further I believe the 56 Roubaix has a 73.25 deg sta which is also more upright for example than the 73.0 deg sta on the size 58 Roubaix. So your more open hip angle due to modest saddle setback will work nicely for your level of drop.
Thanks again.

I leave the bars on probably 75% of the time, only switching a few times a year and leaving it setup that way for weeks or months at a time. They only weigh 380g or so, so it's not a big deal to leave 'em on. One thing nice about Di2 is that I can have shifters on my aerobars and it's still simple to remove them since the wires plug in at the stem.

As I migrate closer to a full on tt position on my road bike, my power output has
Increased, avg speeds have gone up, comfort is wonderful, and i can still do everything else a guy on a regular triangle can do. Personally, im very flexible, and I am a heck of a lot more comfy on my shoulders than my wrists, plus im much faster. My next bike is gonna be a bastardized tt/tri frame.
I, however, have no interest in uci legalities. I only care about the fastest setup.

I like to use the clip-ons my my allez when I am doing a TT or training for one, but the steering is super-twitchy. I have not had a chance to ride a real tri or tt bike, but I have had to quickly swerve to avoid dogs and such, and it is a near crash and a heart-rate spike every time. I know the shorter wheel base of the road bike is probably to blame in theory, but I have no idea how much that holds up in practice. Would these last second maneuvers be safer on a TT bike, or is it just par for the course on any aerobar setup?
FWIW, my set-up is measured for the best position on seat hight, shoulder angle, drop, and setback. It feels great on the trainer. I just can barely steer the damned thing. If I try to move the hand position back, I feel too scrunched up.
