Yakima TubeTop Adapter: The Ultimate Solution for Securing Odd-Shaped Bikes on Hitch Racks

Struggling to mount your step-through, recumbent, or bike with a unique frame design onto a mast-style hitch rack? The Yakima TubeTop Adapter is here to simplify your ride transport needs. Designed for bikes lacking a traditional top tube—common in women’s-specific, hybrid, or retro models—this adapter bridges the gap between your bicycle and most mast-style hitch racks, ensuring a secure fit every time.

Quick & Stable Installation
Attach the TubeTop Adapter directly to your seat post and handlebar stem in minutes. Its oversized aluminum tubing mimics a standard top tube, providing a sturdy connection point for hitch racks that require this structure. Anti-rotation inserts lock into place, preventing unwanted movement during transit while maintaining balance on single or dual-arm mounts.

Protective Design for Your Bike
The adapter’s large molded collars wrap around your stem and seat post without scratching or damaging delicate components. This thoughtful engineering ensures a snug, scratch-free interface that’s ideal for carbon fiber or painted surfaces.

Universal Compatibility
Whether you’re using a Yakima SkyJacker, ForceField, or third-party mast-style rack, this adapter works seamlessly across brands. It’s perfect for commuters with compact city bikes, adventure riders with unconventional frames, or anyone needing a reliable way to transport their two-wheeler without compromising stability.

Why Choose Yakima TubeTop?
Unlike generic adapters that sacrifice security for simplicity, this solution combines fast setup with reinforced durability. Its intuitive design eliminates guesswork, making hitch rack compatibility effortless for even the quirkiest bike frames.

Mount your bike confidently—no matter its shape—with the Yakima TubeTop Adapter.
