These 4.2mm SRAM Frame Plug refills are a workshop staple for any build involving internal cable routing or a conversion to a 1x or wireless drivetrain. Unused cable ports left open in a frame attract dirt and moisture, can cause rattles, and leave the frame interior exposed to corrosion — a simple plug fixes all of that instantly. This refill pack of 25 keeps your tacklebox stocked so you're never caught short mid-build.

Each plug snaps securely into the port with a flush, factory-finished appearance. The 4.2mm size covers the smaller cable entry ports commonly found on modern full-suspension and hardtail frames, particularly front derailleur cable ports on bikes converted to 1x, or dropper post ports on frames without a dropper installed.
