The Seat Tube

I have been stuggling with seat tube issues on my second and third build. The tubes are warping quite a bit and reaming has been hell for a variety of reasons.

I had hoped to rectify this by constructing a tube from NOVA Cr-Mo OS Road Down Tube 31.7 X 650mm X 8/5/8 ($15.00) Welded to a 1.125" OD, 27.2 mm ID Insert.

This was way too heavy. It also threw off an estetic scale for the frame.

Then I decided to go to a NOVA CrMo EXTERNALY BUTTED SEAT TUBE 28.6 x 0.9/0.6/1.2 x 460mm ($13.80) and machine the end down to 1.125" to save a little weight and add a trick look to the tube.
