SunRace Downtube Cable Stops - GLSRDTAS

Downtube bosses are small threaded mounting points located on the downtube of a bicycle frame, traditionally used for water bottle cages or cable guides.

No, the finger-adjustable covers allow for manual tightening, and the stops simply thread onto existing downtube bosses.

These are primarily designed for shifter cables when using STI levers. While they might physically hold brake cable housing, it is not their intended application and may compromise brake performance.

They are made from ball-burnished alloy with black plastic finger-adjustable covers.

These are best suited for road, gravel, or touring bikes where downtube bosses are commonly present and STI levers are used. They are generally not used on modern mountain bikes which typically have different cable routing solutions.

The SunRace Downtube Cable Stops are supplied in pairs, meaning you receive two cable stops.

While painting is possible, it may affect the finish and the function of the adjustable covers. It is not a recommended modification.

Ensure you are using a standard downtube boss. Verify the cable stop is correctly oriented. If the boss is non-standard, this product may not be compatible.

Ensure the finger-adjustable cover is tightened sufficiently to grip the cable housing. Check that the cable housing end is clean and not damaged.

Re-check cable routing for any kinks or excessive friction. Ensure housing is fully seated. Adjust cable tension at the derailleur or shifter if necessary. Confirm the correct cable stop orientation.
