Product Description

Topeak Zi:RAK Essential Rack – Lightweight Modular Carrier for Bikepacking

The Topeak Zi:RAK Essential is one of the most versatile rear racks for modern bikepacking, extended tours, and daily commuting. Combining lightweight design with high stability, it bridges the gap between a traditional rack and a bikepacking seatpack. Enjoy more carrying capacity than a seatpack while keeping a rattle-free, trail-ready ride.

Stable as a Rack, Sleek as Bikepacking

Specially engineered joints keep the Zi:RAK Essential rock-solid on rough terrain. No wobble, no rattle, no side-to-side swing – even with heavy bags. Paired with the optional U-Shell Drybag, it merges the security of a fixed rack with the versatility of a seatpack.

Optimal Balance of Weight, Space & Function

Perfectly tuned for light weight, high load, and practical usability. Offers significantly more carrying space than standard bikepacking seatpacks, while remaining light enough for gravel adventures, sporty tours, and daily commuting.

Maximum Flexibility with Modular Mounting

Mounts to frame eyelets, seat stays, or via optional thru-axle. Height-adjustable legs ensure a perfect fit for different frame geometries. Additional mounting points allow accessories like bottle cages, cargo cages, or fork bags.

Perfect, exactly what I expected

This rack is very easy to install on my Scott Addict. The installation is very stable and doesn’t interfere with pedaling. Thanks to Mathias for his quick responses and great advice

Nachhaltig verpackt

Sustainably packaged.

Nature is very important to us. That's why we avoid unnecessary plastic and rely on packaging material made of paper or cardboard. If your package does contain plastic filling material, this is material from our suppliers which we have reused.
