Description

This rail is designed for areas on your bike without standard mounting points. As part of the B-RAIL System, it lets you quickly swap accessories—making it easy to adapt your setup for any ride.

 

The best installation method is to use double-sided foam tape first — I recommend using two pieces sized 20 × 40 mm (NB004 from the Bambu store). Before applying the tape, make sure to clean the surfaces thoroughly for maximum adhesion.

 

Once the rail is in place, add at least two zip ties through the provided slots to clamp down the rail.

 

Several versions of this part are available to fit different tube shapes and geometries. Please check the images to see all variations and choose the one that best matches your bike before printing.

 

For a complete list of compatible accessories, visit the Official B-RAIL Mounting Rail page.

 

Enjoy your new No-Screw Rail for the B-RAIL System! 🚴

 

P.S. We’re continuously improving the B-RAIL ecosystem! If you have ideas or suggestions for new accessories, feel free to share them in the comments.
