the TT bike is back

Finally finished building my Cervelo P3C time trial (TT) bike after being on hiatus for nearly 5 months. I got new basebar, shifters and rear derailleur for the bike. The basebar is a flat black VisionTech integrated. The shifting is now being provided by SRAM- their carbon A900 bar-end shifters and a SRAM rear derailleur. A new saddle- Fi'z'ik Arione Tri2

Upon building the bike and tuning the shifting on the repair stand, I was having trouble getting the shifting to fall correctly into each gear. I switched the housing and cable to SRAM specific and the problems continued. However, when riding and shifting, I found that it was actually tuned correctly, but the indexing is sensitive on the shifters. Much different than shimano.

Did a 40 mile ride with the bike and my legs were feeling great. I am finding that my position isn't comfortable. This is further worsened by the narrow position of the aerobar extensions. Because the aero setup is intergrated, the width of the aerobar extensions are not adjustable. Also the new saddle puts me in a lower saddle height from center bottom bracket totally changing my position. I will most likely need to make a trip up to Atlanta for Mike to take a look at my position on the bike.

I'm just going to train and play trial and error on the position in hopes to not cause a potential knee injury and build on steady tempo training.
