Redline Techmatic USA BB Set

If you are familiar with the Redline Flight Crank, you probably know what a Techmatic Bottom Bracket is. The Techmatic wasn’t just a solution for the installation of the Redline 401 Flight Crank, it was a piece of precision engineering worthy of Redline’s reputation

Using the original Redline blueprints, drawn by Linn Kastan draftsman, Duke Romero, Redline manufactured the Tecmatic BB cups and packaged them with a teflon-sealed bearing from IJK Japan, just like the 1980s version.
