  • KICKR CORE requires minimal cleaning and maintenance if dirt or grime collects. If cleaning is needed, clear any debris and use a moist, soft cloth to wipe surfaces, avoiding dripping moisture into any part of the KICKR itself. Also avoid using strong cleaning agents as these may damage or reduce the lifespan of your KICKR.

    1. KICKR CORE comes with legs detached to minimize transportation and storage size. Select a stable, level surface with sufficient room for trainer and bike. Retain packaging for future storage or transport.

    2. Attach the legs by inserting the included bolts through the bottom of the trainer leg assemblies, then secure them using the included nuts and hex wrench tool on the opposing side. Repeat the process for the second leg and tighten all bolts firmly to prevent injury or damage.

    3. After attaching both legs, pull the front leg completely forward to fully extend the trainer base and ensure maximum stability before attaching your bike.

      Warning: always check trainer stability before riding.

    4. Use the included AC power adapter to connect the trainer to a standard 120v wall outlet.
      Caution: use of unofficial power adapters may cause permanent damage.

    1. REQUIRED TOOLS:

       
      • Cassette Lock Ring Tool (Park Tool FR-5 or similar)

      • Adjustable Wrench


      Though the video below shows cassette installation on a KICKR '17, the process is identical for KICKR CORE. If you're uncomfortable with installation or don't have the required tools, consider consulting your local bike shop for further installation assistance.


      STEP-BY-STEP INSTRUCTIONS:

       
      1. If installing anything other than an 11-speed cassette, first install the 1.8mm spacer included with the KICKR CORE. 11 speed cassettes do not require the 1.8mm spacer.

      2. If your new cassette includes an additional spacer, install this before installing the cassette. Otherwise, install the new cassette on the freehub body directly. Be sure to properly align each cog with the splined freehub body.

      3. Complete by installing the cassette lock ring and tightening by hand. When snug, tighten with an adjustable wrench another 6-10 clicks (roughly 1/4 turn) to secure.

  • Note: the reversible axle spacer pre-installed on KICKR Smart Trainers is set to accommodate 130mm spacing. Most road bikes use 130mm spacing, while cyclocross and mountain bikes with quick release skewers and disc brakes use 135mm spacing. Please reverse the spacer before mounting a bicycle with 135mm spacing or use the appropriate adapter for wider hub spacing and thru-axle bikes.

    1. Remove your rear wheel, beginning by shifting into the smallest rear cog and smallest front chainring. Release your rear brake before opening the quick release lever (or removing the thru axle, if applicable), then lift the frame while lightly pushing down on the rear wheel to remove it.

    2. Align the dropouts over the trainer’s quick release skewer and gently extend the derailleur to the rear, pulling the chain taut. For thru axle bikes, center the bike’s rear axle with the matching axle hole in the KICKR drivetrain.

    3. Lower the frame over the trainer axle, ensuring the chain falls onto the smallest cog. The axle should slide easily into place. For thru axle bikes, reinsert the thru axle after mounting the chain on the KICKR, screwing it securely to the frame through the KICKR drivetrain

    4. Rock the frame back and forth to ensure the dropouts are fully seated on the skewer. Firmly tighten the quick release - you should feel resistance when half closed; fully closing should leave an imprint on your hand.

    Warning: the quick release skewer must be completely tightened before riding, requiring significant effort and leaving a defined imprint on the hand. Failure to properly tighten the quick release may result in damage or personal injury. If unsure of proper tension, consult your local bike shop or contact support for assistance. Do not ride the KICKR if the quick release skewer is not properly installed. Check skewer tightness and secure mounting before every ride to avoid injury or damage.
