• CUSTOM FIT FOR KICKR CORE (GEN 1 ONLY) Precision-engineered specifically for the Wahoo Kickr Core (Generation 1) leg profile (Inner Diameter: ~2.18"). This adapter provides a snug, secure fit specifically for the original model. (IMPORTANT: Please verify your trainer model before purchase. This item is NOT compatible with the newer Kickr Core Zwift One or other versions with different leg shapes).
• COMPLETE KIT WITH 8 TENNIS BALLS Comes as a complete set including 4 rocker feet adapters and 8 brand-new tennis balls. No need to source balls separately—everything you need for the upgrade is in the box. The design ensures a perfect fit for standard tennis balls, making assembly straightforward and hassle-free.
• DYNAMIC MOTION | Realistic Road Feel Simulates the natural side-to-side sway (approx. 10°) of outdoor cycling. This dynamic movement engages your core muscles and eliminates the rigid, static feeling of stationary training, making your indoor sessions more immersive and enjoyable.
• ENHANCED COMFORT & VIBRATION DAMPENING The tennis ball suspension system acts as a shock absorber for your bike setup. It significantly reduces vibration transfer to the floor (great for apartments) and allows the bike to move slightly with your body, helping to minimize saddle discomfort during long endurance workouts.
• EFFORTLESS "PUSH-FIT" INSTALLATION No hammers or special tools required. Unlike some adapters that are overly tight, ours feature a perfectly calibrated tolerance. Simply insert the tennis balls into the mounts and slide the adapters onto your trainer legs with a firm push for a secure fit in minutes.
