NEW INVENTORY OCTOBER 2023 Redline Tecmatic Bottom Bracket

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, we manufacture the Tecmatic BB cups in California and and package them with a teflon-sealed bearing from IJK Japan, just like the 1980s version.

Included -

2 x Aluminum Cups

2 x Threaded spindle nuts

2 x Redline Decals

2 x Sealed IJK Bearings.
