Keep your internally routed frame pristine, quiet, and completely shielded from the elements. The Jagwire Closed Type Frame Plug is a high-grade workshop solution engineered specifically for modern bicycles featuring internal cable routing channels. When modifying your cockpit layout, switching to a wireless electronic drivetrain, or converting your setup to a 1x configuration, original routing access holes are frequently left wide open, creating an entryway for moisture and debris.
Crafted from a durable, high-density rubber compound, this plug is precision-moulded to press securely into standard round frame entry and exit ports measuring exactly 8.0mm in diameter. Because it is a fully enclosed "Closed Type" grommet, it creates a completely airtight and watertight barrier across the open hole. This protects your internal bottom bracket shell, bearings, and electronic components from water ingress during wet winter commutes, muddy trail rides, or routine bicycle washing, while delivering a clean, professional finish.
Enclosed Closed-Type Design: Engineered without an internal cable exit pass-through to perfectly blank off and seal completely unused routing holes.
8.0mm Round Port Architecture: Flexible rubber construction expands slightly to deliver a snug, compression-locked fit inside standard 8.0mm frame ports.
OEM-Quality Construction: Manufactured from industrial-grade rubber that resists cracking, stretching, and breakdown caused by UV exposure or degreasers.
Moisture and Dirt Protection: Seals the inner tubes from rain, mud, washing spray, and road grit, preventing internal frame corrosion.
Streamlined Low-Profile Fit: Sits flush against the frame tube walls to maintain a clean aesthetic and prevent snags on clothing.
Position on Bicycle: Frame tubes (Down tube, top tube, chainstays)
Installation: Press-fit push insertion
Material: Weather-resistant synthetic rubber
Plug Profile Type: Closed / Blind / Blanking grommet
Port Hole Shape Compatibility: Round
Port Diameter Range: 8.0mm
Removable: Yes
Wireless Drivetrain Upgrades: Perfect if you have upgraded to a wireless electronic shifting system and need to completely block off the old, empty mechanical cable entry holes.
Custom Customised Bike Builds: Ideal for bicycle mechanics and home workshop builders who want to give a refurbished or repainted frame a factory-fresh finish.
All-Weather Year-Round Riders: Great for mountain bikers and gravel riders who frequently ride through deep puddles, mud, and water crossings and want to shield their internal frame tubes.
Active Cable Passing Needs: Because this is an entirely solid, closed blanking plug, it cannot be used to guide live gear cables, hydraulic hoses, or electronic wires through the frame.
Small 6.0mm Frame Ports: This plug is strictly sized for 8.0mm ports; it will be far too large to fit into the smaller 6.0mm or 6.3mm routing ports found on many frames.
Because these rubber plugs are designed to fit incredibly snugly to keep water out, they can sometimes be stubborn to push fully flush into a tight 8.0mm frame port. Rub a tiny drop of liquid isopropyl alcohol (rubbing alcohol) around the ribbed neck of the plug before pressing it home. The alcohol acts as a slippery lubricant to slide the plug in effortlessly, and then evaporates completely within minutes, leaving the rubber securely locked and sealed in place without slipping!
