The Explorer is a classic loaded touring rack designed for compatibility with disc brakes that's built to carry larger, heavier loads. 6061-T6 aluminum construction with 6061-T6 aluminum bracket, hollow aluminum tubes, and stainless steel hardware makes it strong and lightweight while the integrated top fender offers splash protection. The QuickTrack mounting system is compatible with Topeak MTX trunk bags and the rack fits all frames with disc brakes. Includes all mounting hardware.
