Thule Sport G2 3rd Rail Kit - In Store

Maximize your Thule Sport G2 bike rack with the Thule Sport G2 3rd Rail Kit — an in-store extension designed to add a third bike to the vacant space on your Sport G2 Bike Rack. This kit is built to fit seamlessly with your existing rack, expanding capacity without compromising stability or safety.

• Includes: 1 x Bike Rail and 1 x Bike Holder — everything you need to mount and secure a third bike on the Sport G2 system.

The 3rd Rail Kit features an adjustable sliding rail, enabling precise positioning of the extra bike for balanced loading and optimal clearance between bikes. A dedicated bike holder clamps the frame securely, helping prevent contact or movement during transit. This thoughtful design ensures quick setup and reliable performance on the road.

Capacity and compatibility: add a third bike to your existing Sport G2 rack, with each bike supported up to about 30 kg in weight. The extension is specifically engineered for the Sport G2 bike rack, preserving alignment and stability across the full rack length.

Ideal scenarios include family trips or group outings where three bikes are a must. The 3rd Rail Kit helps you bring everyone’s bike along without swapping racks or sacrificing security. It’s a practical upgrade for weekend rides, camping adventures, or multi-bike road trips, all while keeping Thule’s trusted engineering at the core.

Installation is designed to feel intuitive for current Sport G2 users — simply position the new rail in the vacant space, secure the bike holder, and tighten for a stable transport setup. The kit’s components are purpose-built to integrate with the Sport G2 system, delivering a cohesive, reliable carry experience.
