What Our Gearhead(R) Experts Are Saying: "I like the Ergo for riders dialing in fit without swapping the whole cockpit. The curved shape really cups the elbows, and the 48 configuration options make micro-adjustments easy. The injected nylon and glass fiber build feels solid, and the 10mm pads offer comfortable support without excessive stack."When we're chasing efficiency in the aero position, comfort and control go hand in hand. The Ergo Injected Armrest Kit from Profile Design forms the foundation of a fit-focused cockpit, offering a smoothly curved shape that naturally cups the elbows and supports steady power output. Constructed from injected nylon reinforced with glass fiber, the armrest platform provides a stable, durable base for aggressive riding. The 10mm EVA foam pads feature a molded textured surface for enhanced grip and consistent support during long efforts. With a bolt pattern that allows 48 possible configurations simply by repositioning the armrest, we can fine-tune reach and width to match our ideal fit. Compatible with all current Profile Design aerobars and earlier systems using F-19, F-22, F-35, or F-40 armrests, this kit is a versatile upgrade for triathletes and time trialists refining their aero setup.
