WAHOO KICKR CORE 2 Smart Trainer with 11-Speed Cassette

The WAHOO KICKR CORE 2 Smart Trainer with 11-Speed Cassette is a direct-drive indoor cycling trainer designed for structured workouts and virtual riding at home. A pre-installed 11-speed cassette means compatible road and mountain bikes can be mounted directly without sourcing a separate cassette. Power is measured with an accuracy of ±2%, giving reliable data for performance tracking and training plans. The unit simulates gradients up to 20% and descents down to 10%, covering the range most riders encounter on real roads. A 5.4 kg flywheel provides realistic inertia for smooth resistance transitions. Maximum user weight is rated at 114 kg, accommodating a broad range of cyclists.

Connectivity includes Bluetooth, ANT+, and Wi-Fi, allowing the trainer to pair with popular cycling applications and the broader Wahoo ecosystem. Wireless firmware updates keep the device current without requiring a cable connection. Compatibility spans 8- to 13-speed drivetrains, along with Shimano HG, SRAM XD/XDR, and Campagnolo systems when the appropriate adapter is used. Hub standards supported include 130/135 mm quick-release, 12 x 142 mm, and 12 x 148 mm thru-axle setups, with wheel sizes ranging from 24 to 29 inches. The trainer runs on 100–240 V AC power, making it suitable for standard household outlets. KICKR Race Mode is included for fast response to changes in power demand during virtual racing.
