I really had a good time setting up my bike for this (like so many here on ST, I'm into bikes). Here's what I did....
I took my cross bike and put on a
Red Shift seat post and mounted a Cobb V-flow saddle on top. The post allowed me to ride at 74 degree seat angle for the technical bits when I was on the hoods and drops and then you can shift it (on the fly) to be 78 degree. You can jump back and forth from steep to shallow while you ride. When it was steep I could settled into a super comfy aero position on my undermount aerobars - Profile pads and Zipp super curvy extensions (they've very similar to Mat Steinmetz' 51 Speedshop bars). it's funny because the shallow position was DEAD ON my cross coordinates and the TT position was almost identical to my tri bike save that my pads on my tri race bike are ~12cm in drop and my Wilderman bike as more like ~9cm in drop.
I ride a noseless Cobb 55 on my TT bike but wanted more cush and more nose as you have to be all over the machine through some of the tricky bits of the course.
I also ran a 1x11 set up and tried to get down to a 36tooth front but couldn't secure that ring before the race so I ran a 40 tooth front with an 11x32 cassette and it was just barely enough - many would I have loved a 36x30 for some of the steep pitches and long climbs.
I also used the new Enve 4.5 disc brake wheels with a tubless 36mm wide tire. Spot on! Could not have chosen a better set up. 112+ miles of wild and nary a flat.
