RISK 20pcs SD300 SD500 Bike Derailleur Electronic Wire Silent Strap Strips Bicycle Charging Cable Electric Internal Cable Damper

The RISK RC310 Internal Cable Routing Noise Dampening Clips are designed to eliminate the annoying rattle and vibration caused by electronic shifting wires moving freely inside a carbon or alloy frame. Each clip features a dual-size, two-in-one design — the larger opening fits Shimano SD50 E-Tube wires, while the smaller opening fits the newer SD300 E-Tube wires. Simply snap the clips onto the wire at regular intervals before routing it through the frame; the clips press gently against the inner frame wall, holding the wire in place and absorbing vibration. Made from flexible high-strength polymer via 3D printing, the clips are lightweight (approx. 0.45 g each) and can be trimmed with scissors if only one end size is needed. 20 clips per bag — enough for a full bike build.

— Key Advantages —

• Eliminates wire rattle — stops electronic shifting wires from knocking against the inside of the frame, giving you a quiet, rattle-free ride
• Two-in-one dual-size design — larger end fits SD50 E-Tube wires, smaller end fits SD300 E-Tube wires; one clip works with both generations of Shimano Di2
• Trim-to-fit — if you only need one size, simply cut off the unused end with scissors
• Lightweight — approx. 0.45 g per clip; 20 clips weigh only approx. 9.1 g total — no meaningful weight penalty
• Flexible polymer material — high-strength resin flexes to snap onto wires and conform to frame interior shapes without damaging cables or paint
• Easy installation — no tools required; just clip onto the wire at 5–10 cm intervals before internal routing
• 20 pieces per bag — sufficient quantity for a complete road bike with front and rear derailleur wires
• Compatible with internal routing frames — works with most carbon and alloy road frames with internal cable routing channels

— Compatible Products —

• Shimano Di2 electronic shifting systems — including Dura-Ace (DA), Ultegra (UT), and 105 series electronic groupsets
• SD50 E-Tube wires — the standard / older generation Di2 wires (larger diameter)
• SD300 E-Tube wires — the newer, thinner Di2 wires used with 12-speed Di2 systems
• Road bikes with internal cable routing — carbon or alloy frames with internal wire channels for electronic shifting
• Can also be used to reduce rattle from other small-diameter internal cables (e.g. hydraulic hose rattle in some frames, though primarily designed for Di2 wires)

— Notes —

• Electronic shifting wires and frame are NOT included — this listing is for the noise dampening clips only; wires, derailleurs, and frames in photos are for display only
• 3D-printed finish: layer lines and minor seam textures are inherent to the 3D-printing process and are not defects; they do not affect function
• Measure before trimming: if you plan to cut off one end, confirm which wire size you need first; trimmed clips are non-returnable
• Spacing guide: for best results, install one clip every 5–10 cm along the wire, paying extra attention to areas where the wire passes through wide frame sections (e.g. down tube, seat tube)
• Do not overtighten or force — the clips are designed to snap on gently; forcing them may crack the polymer or damage the wire insulation
• Avoid sharp frame edges — when routing, ensure the clips do not get caught on sharp internal frame edges or cable port openings
• Manual measurement: dimensions and weight may vary slightly due to hand-measuring and 3D-printing tolerances
