What customers say
The Profile Design Race-H Armrest Kit earns strong praise, primarily for its superior comfort and stability in the aero position. Cyclists value the ergonomic H shape, which offers excellent forearm support, crucial for maintaining an aggressive posture over long efforts. Reviewers consistently note the high quality and robust construction, justifying the premium investment. The adjustability allows riders to precisely fine-tune their fit, effectively reducing common pressure points and numbness associated with standard armrests. While the kit is overwhelmingly positive, some ultra-endurance riders suggest the stock padding could benefit from more cushioning for very long rides. Overall, this kit is recognized as a top tier component delivering significant performance and comfort advantages.
Know before you buy
The Race-H features the same refined curvature as the Race+ but includes a higher outer wall. This design is specifically intended to provide extra support for riders who prefer a narrow elbow position.
The Race-H kit is designed for wide compatibility. It supports five distinct bolt spacing options: 12.5mm, 14mm, 16.5mm, 18.5mm, and 29mm, making it adaptable to a broad range of aerobar setups.
The armrest cups are constructed from a durable injected nylon and glass fiber composite. The included pads are made from EVA foam, which provides a balance of comfort and stability.
The complete kit weighs 246g per pair. This includes both the armrest cups and the EVA foam pads.
The kit comes with M6 x 16mm stainless steel hardware. This standard size is chosen to ensure reliable, corrosion-resistant mounting across various aerobar configurations.
