What Our Gearhead(R) Experts Are Saying: "I recommend the Ergo to athletes looking for more forearm support without overhauling their entire cockpit. The longer 124mm platform noticeably spreads pressure, and the updated surface pattern keeps you planted when you're sweating deep into a race effort. Easy comfort upgrade for most Profile Design aero setups."When we're committed to staying aero for the long haul, small comfort gains add up fast. The Ergo Armrest Kit from Profile Design builds on the proven Ergo shape, extending the platform to 124mm for increased arm contact and reduced pressure during sustained efforts. With a 16mm stack height and refined ergonomics, the Ergo distributes load more evenly across the forearm, helping us hold position longer with less discomfort. A newly developed surface pattern improves grip and assists with sweat management, keeping contact secure in hot race conditions. Designed to pair with current and recent Profile Design aerobar models, this kit is a straightforward comfort upgrade for triathlon and time trial athletes chasing efficiency and stability in the aero position.
