Frequently Asked Questions
Q: What size cables does the bicycle frame foam damper fit?
A: This foam cable damper is designed for brake lines, gear shift cables, and hydraulic hoses with an outer diameter of up to 6mm, making it universally compatible with the vast majority of MTB and road bike cable housings.
Q: How do I install the inner cable foam damper inside my bike frame?
A: Thread your cable housing through the foam tube before routing it through the frame. The flexible sponge foam bends freely around tight curves and through frame ports without creasing, so simply guide it through your internal routing channels as you would a standard cable housing.
Q: Will the foam damper scratch or damage my bike frame?
A: No. The soft sponge foam acts as a gentle buffer between the cable housing and the inner frame walls, protecting your frame finish from scuffs, vibration wear, and metal-on-frame contact.
Q: How many pieces do I need for a full bike cable setup?
A: Most riders will need 2 pieces to cover both brake cables and shift cables on a full internal-routing frame. The 2-pack option is ideal for a complete setup, while the 1-pack suits a quick single-cable fix or upgrade.
