In case you were wondering what shape the latest team frame would take, here it is. As of this year of 2019 I think I have a winning combo of new features. Yes, I have built others like this earlier but only a few so far- probably only 4-5 at this time.
The top tube has been ovalized in two planes with one section being flattened for more comfort when shouldering. I'm pretty late in the game adding this feature but I had to find suitable tubes before I could pull it off. it will now be a standard feature on the race frames.
Another feature is actually the absence of an old one- the seat stay bridge is gone- at the top of the seat stays there is a small plate gussett to strengthen the area where the stays meet the seat tube. More stress is put on this area with the removal of the bridge so this plate at the top of the stays disperses that stress and adds a little stiffness to the rear triangle. Finally , the flat mount brake with internal down tube routing is something I have been switching to in the last 6 months . The result is the sleekest version of the team frame yet.
