Bicycle rear rack mount TOPEAK TA2406 — polymer, 320×94×61 mm, black

TOPEAK TA2406 is a polymer mounting platform designed to convert a standard bicycle rear rack into a stable attachment point for trunk bags, rear baskets and other rack-mounted accessories. The part measures 320×94×61 mm and has a monochromatic black finish. Supplied as a single-piece platform, it forms a flat, durable interface that helps secure loads and keep accessories aligned on the rear of the bike.

Advantages

The polymer construction provides a lightweight yet robust platform that resists corrosion and reduces vibration transfer to attached bags. The broad 320 mm platform area delivers stable support for containers and accessories while the compact depth and height maintain a low profile on the rack. The single-piece design simplifies installation and reduces points of failure compared with multi-component adapters.

Suitable for

• Mounting trunk bags and rear baskets on commuter and touring bicycles
• Attaching cargo containers for grocery or small-load transport
• Adapting a standard rear rack to accept Topeak TrunkBags and compatible accessories
• Use on children’s ride-on bikes where a stable, lightweight mounting platform is required

How to use

Position the platform on the rear rack so the broad face aligns with the rack deck. Secure the adapter to the rack using the supplied or compatible mounting brackets and fasteners, adjusting bracket spacing to match your rack tube width and diameter. Once mounted, attach the trunk bag or basket to the platform according to the accessory manufacturer’s instructions, ensuring attachment points are tightened and the load is centered for stable riding.

Usage recommendations

Verify compatibility between the TA2406 platform and your specific rack system before mounting—measure rack tube diameter and overall rack width. Distribute weight evenly and avoid exceeding the bicycle manufacturer’s rear rack load limit. Periodically check fasteners for tightness and inspect the polymer platform for cracks or excessive wear.
