RISK RC310 Internal Cable Routing Noise Dampening Clips for Electronic Shifting — Fits Shimano Di2 SD300 & SD50 E-Tube Wires, 20PCS / Bag

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
