I'm building my bike in sub-assemblies and have the dt-ht bit done... but it's 59.6 degrees instead of 59.2 degrees. In theory, I know I insert some thicker wall tubing down the down tube and head tube and then crank. In practice, I've already sunk some water bottle bolts through the down tube. I decided to give it a shot anyway, and braced the head tube with a scrap piece of tubing and really put some weight on it... and it seemed to move a bit, but when I checked it a few minutes later, it was right back at 59.6. So... do I just push harder? Am I hosed?
I have another set of tubes/lugs coming, but I'm hoping that they're for bike #2 ;-)
