The Blue Lug Downtube Shift Boss Cover is a small finishing detail designed to neatly cover unused downtube shifter mounts. Created by Blue Lug, it’s a simple solution for keeping your frame looking clean when running alternative drivetrain setups.
The shape is designed to match nicely with common Shimano and Dia-Compe cable stop hardware, helping maintain a tidy and cohesive look on the frame. It’s especially useful when converting bikes such as the Surly Straggler or Cross-Check to a 1x drivetrain or when building a single speed setup.
By covering exposed shift bosses, these caps help complete the overall appearance of your build while keeping things minimal and functional.
