The Topeak Zi:RAK Thru-Axle is a smart solution for mounting Zi:RAK rear racks on bikes without traditional rack mounts. It replaces your original rear thru axle and creates a secure attachment point, making it ideal for road and gravel bikes, especially those with carbon frames.
Featuring integrated M5 threads on both sides, the axle serves as a direct mounting interface for the rack. This allows you to easily upgrade your bike for commuting, touring, or bikepacking without the need for frame eyelets.
Available in multiple thread pitches (M12 x 1.0, 1.5, 1.75, and SRAM UDH), it adapts to a wide range of frame standards. Included spacers ensure a precise fit and secure installation tailored to your bike.
Made from lightweight aluminum, the Zi:RAK Thru-Axle offers a strong yet lightweight solution for riders who want to expand their bike’s carrying capability while maintaining a clean and minimalist setup.
