Who Is This For?

If you know a bike mechanic that’s been around for a while, you may notice that they sometimes get a little nostalgic for 9-speed drivetrains.  9-speed is super versatile, easy to adjust, and tolerant of all kinds of abuse.  R9 embodies that versatility and durability.  With a wide variety of shifter, derailleur, and cassette options, you can use R9 to set up a road bike almost any way that you want.  It also slots in easily as a replacement parts if your existing drivetrain wears out or breaks.  It’s not fancy, but sometimes normal is exactly what you’re looking for.
