Small tubes, big performance.
The FLAER Di2 Tubing Kit takes advantage of the streamlined designs of both Shimano's electronic drivetrain as well as their Revo Via to provide their power-improving lubrication to your drivetrain. These low-profile tubes integrate perfectly with a bike running Di2, providing the same flow rate of the larger stock tubes yet in a sleeker design.
Keep things running smoothly on your road, mountain, or commuter bike.
When to use grease, lubes, and solvents on bicycle parts.
