Where are you putting your blip box?
And are any of you guys running rotor cranks?
What's your CdA?
I'm thinking about swapping out the Ultegra 50/34 crank for either a 50 or a 52 1X aero crank, preferably with a power meter. As a flatlander without a whole lot of watts to burn I use a 12/25 rear cassette and I find myself using the 50 x 16 in flat. neutral conditions which would give me plenty of room to gear up or down as need be. Using a 52 would mean moving up to a bigger rear sprocket which would change the chain alignment, perhaps for the better?
So any of you folks have an opinion on a specific piece of equipment that might work?
52x17 (middle sprocket 12/25) at a FDR of 3.058 @ 90rpm yields 21.60mph
50x17(middle sprocket 12/25) at a FDR of 2.941 @ 90rpm yields 20.77 mph
Realistically I'm going to average 20.0 to 21.5 at best on a 56 mile course (which for my AG isn't so bad)
Thanks in advance for your help...

I have 2 holders in my frame but they create a lot of drag and reaching down to get them I come out of aero position, looking for rear holder behind the seat or something for the aero bar? I got a 2018 sc and then whole front end is integrated and I am unsure if anything fits there.
The XLABS Torpedo will fit there, although depending on how things are setup you may need to use the Bontrager mounting bracket to hook the torpedo setup up to. I had mine attached without but wanted it positioned a little different, so had to add the Bontrager mounting bracket.
Have a 2 bottle behind the seat when needed.
Youâ€™d need a SC stem, riser, basebar, and extension. Thereâ€™s also hardware (bolts, etc) that would prob be best ordered through dealer. But the big items should be somewhat easy to source on your own.
Then building it up isnâ€™t that bad if youâ€™re comfortable wrenching.
Good luck finding a SC basebar. Not saying they cannot be found, but only part I could not find a few months ago that I needed to fix the bike. Had to go to a dealer.

If the bike you bought is 600 OCLV its a 2017 or older 9 series frame.
In a large the says with the far stem you can reach 584 but.........if you use the trek extensions and Max out the pad reach you really can't have normal sized for arms. There extensions are not long enough by a long shot. So you change to plug that let's you run what extensions you want but you the loose 2.5 cm of capable reach. So now from a Max of 584 to 560....
And if you stay with there extensions and Max the pad reach to 584 you need dwarf fore arms....
GREAT THINKING TREK!
I am not sure if this has been posted or not somewhere in this long thread but I figured I would post it now. I see a lot of questions about the mono-plug in and its fit and comparison so I figured I would type up a little post and give some photos with it.
The biggest question of all - the mono plug in is 1 inch shorter than the standard mono bar that is provided (My example is the Long Ski-tip) on the G2 SC for the armpad mounting holes.
However, I stated this in another thread and verified this yesterday that in real world application you can get more "reach" out of the plug-in than you can a standard bar.
I ride a Medium SC, Trek states that a Medium can have a reach of up to 56cm (I measured 57cm on my bike to the center of the pad at maximum reach) - However when you calculate my forearm and hand into the equation I can ONLY get a maximum of 51.5cm, it is not physically possible to reach any further than that.
You add the mono plug in to the bike and although it is "shorter" I can run the center of the armpad to 54.5cm - so when adding whatever extensions I want and making them to the length I require I have gained 3cm of reach over the standard mono bar!
Here are some photos of the bars;
The bars right next to each other
The bars stacked on top of each other and bolt holes line up
The bars next to each other and holes
The standard mono bolt hole to bolt hole length
The standard mono bolt hole to ski-tip length
ANY mono bar with grub screw back (hindering reach)
Any mono bar with grub screw forward (allowing for maximum reach)
The standard mono bar with "longest" reach possible (in my case)
Any mono bar set up for maximum reach possible (bridge flipped, bar slide as far forward, pads forward maximum)
The Standard Mono bar with "longest" reach possible and my arm (my elbow bone right behind end of pad)
I hope this helps with some of the questions that have been on and off this forum about this bike!
Distance between pad wing mounting holes on the mono aero bar (both regular and plug-in) - 22.5mm
Off set between the pad wing orientation - 30 mm
Pad holders mounting holes - 15 mm x and y
Question on the set screw. The role of the set screw or the grub screw is to take some pressure of the rocker (/ cradle / whatever that piece is called ) bolts when using tilt. I remember a bunch of people complaining here that they were constantly shearing their bolts when using tilt... it's because they were not using the set screw correctly i.e. you should set it so it touches the mono spacer.
I'm not sure but maybe reversing that piece negates the purpose of the set screw and could cause some issues to those that use the tilt mechanism.
