Upgrade your Saris H1/H2/H3 with rocker feet and ejoy longer more comfortable rides! Stationary trainers are fixed and don't allow the bike to move naturally, which can lead to discomfort during long rides. Rocker plates allow for slight lateral movement, reducing pressure on the saddle and providing a more dynamic and comfortable experience. Unscrew the original feet, place 2 feet on legs, place 3rd rocker under trainer, and place tennis balls under each rocker foot. 💙 3D Printed Using Robust PETG Filament🍰 Simple Installation📏 Fits Saris H1, H2, and H3🎯 3 Rocker Feet Per Set🚴♀️ Already Printed and Ready to Ship🦅 Veteran owned company🌵 Made in Texas *If you are not into the Texas logo, the other side is blank.
