Topeak Zi:RAK Essential Rear Rack - Seatstay Mount

The Topeak Zi:RAK Essential Rear Rack is a lightweight rear rack system for road and gravel bikes, built to carry up to 22kg with stable mounting options and wide tyre clearance up to 700x55c. It supports both eyelet and quick-mount setups, giving flexible fit across different frames. The rack includes pannier side frames and works with Topeak U-Shell Carrier and Drybag systems. Its aluminium and engineering-grade polymer construction keeps weight low while maintaining strength for daily use and longer rides.Key Features and Benefits:Two mounting options (eyelet or quick-mount): The rack can be fixed to frame eyelets or attached using a seatstay quick-mount system. This allows fit across more bike types, ensuring secure installation even on frames without traditional rack mounts, which results in a stable and reliable carrying setup.22kg load capacity with defined load zones: The rack supports 6kg on the top platform and 8kg on each side. This structured load distribution reduces stress on key mounting points and keeps weight balanced, which improves control and reduces unwanted movement during riding.Integrated pannier side frames: Built-in side supports keep pannier bags aligned and clear of the wheel and drivetrain. This prevents contact and sway, resulting in consistent pedalling and reduced risk of interference on uneven surfaces.Compatibility with Topeak U-Shell Carrier and Drybag systems: The rack is designed to work with Topeak's modular luggage system. This ensures secure attachment points and reduces shifting, which leads to a more organised and stable load during use.Lightweight aluminium and polymer construction: The combination of aluminium and engineering-grade polymer lowers overall system weight while maintaining structural strength. This keeps handling responsive while still allowing the rack to support heavier loads.Wide tyre clearance up to 700x55c: The rack is shaped to fit bikes with larger volume tyres. This ensures compatibility with modern gravel setups, allowing you to run wider tyres without restriction while still carrying gear.A secure and adaptable carrying system helps maintain control when transporting gear. The dual mounting design supports both fixed and quick-fit setups, so the rack can be matched to different frame types without compromising stability. The defined load zones and pannier support structure keep weight controlled and centred. This leads to more predictable handling across varied terrain and longer distances.This rack provides a practical way to carry equipment without adding excess weight or complexity. It supports common luggage systems, fits modern gravel bikes, and holds loads in a stable position. A dependable option for regular use, commuting, or extended rides.Specification:Attachment: Seatstay Mount / Eyelet MountCompatibility: Fits bike tyres up to 700x55C / 29" x 2.5" (not compatible with full-suspension bikes) / Topeak Pannier Drybag, U-Shell, QR Fork Drybag, and VersaCageMaterial: Aluminium, engineering-grade polymer, nylon strapsMax load: 22kg (6 kg top/8kg per side )Size: 47.5x42x18.5cmWeight: 660g (Eyelet Mount) / 720g (with Seatstay Quick-Mount)
