About the saddle height.. The picture was taken while I was coasting down hill and not really pedalling. I'll try to take some better pictures soon. I think I scoot forward on the saddle when I'm really riding and my legs feel cramped in there. My arms and back are looking ok, but they probably look better now that I've adjusted the stem and put the pads on the armrests.
I don't know what my best 40k tt time is. For 20-30 minute intervals I can do almost 300 watts on my road bike. I'm 60kg. I hope I don't lose too many watts in a tt position but I will find out soon. I don't yet have an aero helmet but I won't be doing any tt races until next year. The season is ending and I want to practice more on the tt bike before I do a race.
Tillquist: There is no bottom bracket really. There are pressfit bearings in the frame with an axel pressed into them. The axel has no shoulder so you can move it to adjust the chainline a little. You put spacers between the axel and the cranks to prevent it from moving once it is in place. The headset is also very special and does not require preloading.
The bike was somewhat daunting to build. I spent several days and had the help of carbonfiberone at many stages. He drilled and tapped the frame today so I could mount a bottle cage for longer tts and training rides. I got an arundel chrono aero bottle that is supposed to improve the aerodynamics a little even.
I still have to further cut the extensions and paint the fork before it is totally done.
The ride is incredible. It feels more stable at high speeds. I took it up to 35 mph (56kph) and it felt great, like it should always go this fast.
The bars are very comfortable out of the saddle if you hold them right. The frame is very stiff and is unlike anything I've experienced when standing. In the aero position I still have some work to do to get more comfortable and see where my power output is. After the first 10 miles I felt very confident on the bike and am impressed by the handling.
It just looks so much more incredible in person than in the pictures. When I ride it I feel like I'm on a fighter jet more than a bicycle. The bars especially look very agressive and are also rock solid. The whole bike has a very solid, slightly overbuilt feel to it, like you can't break it.
More pictures after my roommate with ugly furniture and a nice camera wakes up, and hopefully soon I'll know my speed at threshold.
