RockyMounts MonoRail Add-On

This is a one bike add-on to turn your MonoRail 2-inch (sold separately) into a three bike carrier. Simply remove the end cap from the MonoRail, slide the attachment in and it quickly secures with two bolts. The cable lock included with the MonoRail is long enough to secure all three bikes. Simply and easy. Not compatible with 1.25-inch MonoRail.
