In the next week or so I am going to purchasing and building up my first TT bike and am looking for some suggestions for the build. The bike is going to be the ridley Dean, wheels are good (Zipp disc rear with reynolds SDV66 front as it's what I already have), as is the component group for the most part (shimano dura ace/ultegra/105 mismatch, though am debating trying out the sram stuff). Cranks may be something else if there is a reason to change from the standard shimano ultegra that would match the rest of the group.
The cockpit is what I'm having the hardest time with. Adjustability is the number one priority because I assume I'm going to be playing with the position for a while until I have it dialed in. The oval concept would be what match the bike, but I've heard good things about the vision stuff too and I really like the way it looks or I could go with profile which I can get a great deal on. Oval is definitely more expenisve, not sure if it's any better though, vision looks the best, profile is the cheapest. Straight bar or a slight S bend preferably. I know seats for road riding are very personal, but I was wondering if there are any general recommendations for a good TT seat out there as well. Anything else that I need to know for the first build up would be appreciated as well.
