Assembly

130MM or 135MM Quick Release (QR)

An axle adapter is required on both sides of the KICKR.

• Adapters A + B are required.
• Note the asymmetry of adapter B. When used with a 130mm bike, the longer side of the adapter should be inserted into the trainer. When used with a 135mm bike, the shorter side should be inserted into the trainer.
• Insert the skewer into the wide end of one spring, then into Adapter B, then into the trainer from the non-drive (left) side.
• Slide the longer end of Adapter A around the skewer and into the trainer from the drive side.
• Slide the narrow end of the remaining spring over the skewer, then thread the wider end of the acorn nut onto the skewer.

142MM or 148MM Thru Axle

• Adapters C + D or C + E are required.
• Note the 142 and 148 labels and directional arrows etched on Adapters D and E.
• When installing a 12x142mm bike, insert Adapter D into the non-drive (left) side of the trainer, with the arrow facing toward the trainer.
• When installing a 12x148mm bike, insert Adapter E into the non-drive (left) side of the trainer, with the arrow facing toward the trainer.

Mount Your Bike

For CORE 2 with cassette

1. Shift into the small front chainring and the smallest/highest cog of the cassette to reduce tension on the chain.
2. Open and loosen the quick release skewer or remove the bike's thru axle.
3. Gently pull the bike up and off of the wheel.
4. Gently pull the body of the rear derailleur backwards and lower the chain onto the smallest/high cog of the cassette on the trainer and the bike's frame onto the trainer's frame adapters.

Do NOT ride the CORE until the quick release skewer is tightened.

WiFi Setup

Once paired, the Wahoo app will prompt you to proceed into Wi-Fi setup to allow for automatic firmware updates and the most robust connection available for third party desktop or Apple TV applications. Please see our WiFi support page for more details.

Update Your CORE 2 Firmware

Every new Wahoo KICKR Smart Trainer will require a firmware update to work harmoniously with apps like SYSTM and Zwift, among others. Please see our article on updating trainer firmware for more information.

With a viable Wi-Fi network enabled, the trainer will automatically check for firmware updates and update immediately and automatically via Wi-Fi overnight, provided the trainer has power and is not actively in use.

Registration on the Wahoo Cloud

Trainer registration occurs automatically and silently during the onboarding process as the device is registered to the Wahoo account associated to the paired Wahoo App. Registration status can be found in the Device information page on the app accessed from Devices > CORE > Device information after onboarding is completed.
