Items Needed:

• 2 x non-ratcheted rollerski wheels that are already assembled with new bearings
• 2 x ratcheted rollerski wheels that are already assembled with new bearings
• 2 x 10mm wrenches or socket tools (may be different depending on your rollerski model)
• 1 x 13mm wrench or socket tool (may be different depending on your rollerski model)

Step 1: Removing the Old Wheels
Start by placing your rollerski on a stable surface. Use your 10mm wrench and/or socket tools to loosen and remove the nuts/bolts that secure the non-ratcheted wheels. Use the 13mm wrench to remove the ratcheted wheels. Keep the nuts, bolts, washers and spacers safe, as you may need them to attach the new wheels if the hardware included with your new wheels is not an exact fit for your rollerskis. If the wheels do not slide out easily from the forks, use a hammer to tap the nuts, and the wheels should come out.

Step 2: Installing the New Wheels
Slide the new wheels with the spacers into the skis` forks. Ensure the wheels are set down to the base of the slots in the fork. Make sure the ratcheted wheels spin in the correct direction before tightening. Tighten the nut and bolt with your wrench and/or socket tools, but be careful not to overtighten them, as this can damage the wheels or the rollerski frame. Hand-tight is perfect.

Step 3: Final Check
Give each wheel a spin to ensure it rotates freely and is securely attached. If it feels too tight or too loose, make any necessary adjustments. Double check the ratchets spin in the correct direction.
