Jagwire unisex Foam Inner Sleeve for Internal Hoses, 10 m Roll — Black, 10mm OD, Noise-Reducing Protection

Jagwire's 10 m foam inner sleeve provides a quiet, low-friction lining for internal brake and derailleur hoses inside modern bicycle frames.

Designed to line internal cable channels, this supple black foam sheath reduces rattling and wear where hoses and cables pass through frame cavities. At an outer diameter of 10 mm it accepts common 4 mm and 5 mm hose sizes, and the rollable length lets you trim and position it to match any frame's routing layout.

How does this sleeve cut down on frame noise?

The foam creates a soft, protective barrier between hoses/cables and the frame interior, minimizing movement-generated clinks and vibrations. By reducing direct contact points, it prevents the repeated rubbing that commonly causes annoying noises on rough roads.

• Soft foam composition absorbs impact and vibration.
• Covers exposed hose sections inside frame cavities to stop metal-on-metal or metal-on-carbon contact.
• Continuous 10 m length lets you line multiple stays and junctions without seams.

Will it fit my brake or derailleur hoses?

The sleeve's 10 mm outer diameter comfortably accommodates standard 4 mm and 5 mm hoses and cables used on many modern bikes. You can slit or trim the foam for a snug fit around connectors or through tight grommets if needed.

• 10 mm outer diameter accepts 4 mm and 5 mm hose diameters.
• Flexible material conforms to bends and routing paths.
• Trim with scissors for custom lengths and openings.

How is it installed and adjusted in-frame?

Installation is straightforward: feed the hose through the sleeve and slide the foam into the frame channel, or push the sleeve through first and thread hoses afterward. The long 10 m roll gives you enough material to route through downtubes, chainstays, seatstays and headtube paths, then cut to fit without running out.

• Push-fit or thread-through installation methods both work.
• Cut to size with scissors; split if you need to wrap around preinstalled hoses.
• Black color is discreet inside most frame finishes.

Does it protect hoses and reduce wear?

Yes — the foam layer lowers abrasion and stress at contact points inside the frame, extending the life of hose coverings and seals by preventing constant rubbing. It also helps keep hoses centrally positioned to avoid chafing against sharp edges or internal fittings.

• Reduces friction and localized wear on hose jackets.
• Keeps routing tidy to prevent snagging and kinks.
• Useful for both metal and composite frames to protect finishes.

Who this product is for: Cyclists and mechanics who run internal cable or hose routing and want a simple, effective way to silence rattles, reduce friction and protect hoses inside the frame. It's ideal for riders upgrading hydraulic hoses, tuning shifting systems, or restoring older frames with worn internal liners, and for bike shops that need a versatile, long-length sleeve to serve many builds and repairs.
