【A】TANGE Track frame /530/540/Rear120

Though concrete details are scarce, some educated guesses can be made based on the head tube badge—this frame is likely made by TANGE. The material is aluminum, which is a bit of a departure considering the word PRESTIGE is integrated into the design. While PRESTIGE is more famously known as TANGE’s high-end chromoly tubing, this one appears to take inspiration from that legacy.

It’s possible this frame was built as a training model for track racing. The fork, top tube, and down tube are all aero-shaped, giving it a fast, aggressive look. And that name—infinity—has a nice ring to it, doesn’t it?

Interestingly, the top tube has a pursuit geometry, with a slight downward angle of about 2.5° as measured with a level.

Note: A seat clamp is not included. The seatpost diameter is 27.2mm, so please be sure to have the correct size ready for your build.
