RockyMounts Chain - GuideRail/AfterParty Black, 10mm

What Our Gearhead(R) Experts Are Saying:"I added this to my GuideRail setup after getting tired of cable locks that gave me zero real confidence at busy trailheads. The 10mm square-link construction is a meaningful step up in resistance and the weather-resistant finish has held up through a full season of outdoor exposure without showing any signs of degradation."A trailhead stop should feel like a trailhead stop, not an anxiety spiral about what is sitting on the rack outside. The RockyMounts Chain for GuideRail and AfterParty was designed to close the gap between the security a cable lock pretends to offer and the security a 10mm square-link steel chain actually delivers. Built specifically for GuideRail and AfterParty rack systems, it integrates with the geometry of both the wheel trays and rack arms without the improvised fit that comes from using a generic lock on a purpose-built rack. Square-link construction resists the cutting and twisting attacks that defeat lighter security options, and a weather-resistant finish keeps the chain functional and presentable through seasons of outdoor exposure, parking lots, and trailhead conditions that are rarely kind to metal hardware. It is a straightforward upgrade that costs less than a single bike component and protects everything above it.
