Topeak Tetrarack GR2

The Topeak Tetrarack GR2 is a quick-mount rear rack for road and gravel bikes, designed for fast installation, stable load support, and secure bag integration. A hook-and-loop strap system fixes the rack to the seatstays without tools, while an adjustable top plate keeps the load level across different frame angles. The integrated QuickTrack® system allows compatible Topeak TrunkBags to slide on, lock firmly, and release in seconds. Its aluminium and engineering-grade polymer construction balances strength and weight, with a 9kg load capacity for everyday use.

Key Features and Benefits:

• Hook-and-loop strap mounting system: The rack secures directly to seatstays using adjustable straps, removing the need for eyelets or tools. This allows fast fitting on a wide range of frames and ensures stable positioning, so you can carry loads on bikes that would not normally support a rack.
• Self-levelling top plate design: The top plate adjusts automatically to match the angle of the seatstays. This keeps cargo level during use, which improves load stability and reduces shifting, leading to more consistent handling on uneven surfaces.
• QuickTrack® system compatibility: The integrated rail system allows Topeak TrunkBags to slide into place and lock securely. This creates a firm connection that prevents movement while riding and enables fast removal when needed, improving both convenience and reliability.
• Wide tyre and frame compatibility: The rack fits road and gravel bikes with clearance up to 700x50C tyres and seatstay widths from 80–110mm. This ensures a precise fit across modern gravel setups, allowing you to carry gear without affecting tyre clearance.
• Durable multi-material construction: Built from aluminium, engineering-grade polymer, and reinforced nylon straps, the rack resists flex under load. This improves long-term durability and keeps the platform stable, even when carrying heavier items.
• 9kg load capacity with reflector mount: The rack supports up to 9kg and includes a clamp for a front reflector. This allows you to carry essential gear while maintaining visibility, supporting safer riding in low-light conditions.

A stable and adaptable carrying system is critical for gravel and road use where frame mounts are limited. The GR2 addresses this with a secure strap interface and a self-adjusting platform that keeps loads balanced. The QuickTrack® system adds a structured way to attach and remove luggage without straps or movement. Together, these features provide consistent load control and straightforward day-to-day use across different bikes.

This rack offers a practical solution for adding carrying capacity without complex setup or permanent fittings. Its fast mounting system, stable platform, and secure bag interface make it a reliable upgrade for commuting, training, or longer rides.
