Wahoo KICKR Core Smart Turbo TrainerHelping you keep your eyes on the prize in the off-season and maintain your sharpness when the roads can't be run, the KICKR Core Smart is technologically equipped to keep you in top condition and race-ready all year round. Built with Wahoo's superbly successful silent-design and tech-filled flywheel, the Core supplies true-to-life inertia and power to give you the ultimate real-ride feel. Performance-Focused Indoor Smart TrainerWahoo excels in the world of static training and its latest Core smart indoor bike trainer builds on that reputation by combining wireless connectivity with quality construction. It will accurately track your stats as work up the same sweat as you would on an outdoor escapade. Providing you with brilliantly controlled resistance to make your workout as intense as you wish, the Core is also thru-axle compatible. This means you can easily mount your disc brake equipped bike, giving you unaltered comfort and familiarity as you embark on your indoor sessions.Using Bluetooth and ANT+ technology, the Core syncs with Apple, Android or Windows mobile devices to not only relay your performance stats but put you right in the mix with virtual rides and races for a super-realistic experience. Working in conjunction with excellent VR apps such as Zwift and TrainerRoad, you can immerse yourself in whatever type of ride you want. Alternatively, you can go back through previous real-life rides by connecting up your compatible GPS computer and go for a new PB from the comfort of your garage. The ANT+ FE-C connection also allows the trainer to be controlled from any FE-C enabled device.Starting on August 1st 2019, all new registrations for KICKR, CORE and SNAP will come with a free 30 days of Zwift. The free 30 days will be delivered to new KICKR, CORE and SNAP customers via email once they register their trainer in the Wahoo App on iOS or Android.
