Switching wheelsets on Frog Road & Gravel bikes
Switching wheelsets on your child’s Frog Road or Gravel bike is straightforward. Follow this guide to safely change between road and gravel wheelsets.
Front wheel
1. Remove old front wheel
Open the quick-release lever and loosen the tension-adjusting nut enough to allow the removal of the wheel from the dropouts
You may need to tap the top of the wheel with the palm of your hand to release the wheel from the front fork
Caution: Disc rotors have sharp edges, and both rotor and calliper can get very hot during use.
Caution: Make sure that the clamping action results in a completely secured wheel that embosses the surfaces of the dropouts.
Caution: Be careful not to damage the disc, calliper or brake pads when re-inserting the disc into the calliper. Never activate a disc brake’s control lever unless the disc is correctly inserted in the calliper.
2. Install new front wheel
Ensure the QR lever is in the open position, insert the wheel between the fork blades so that the axle seats firmly at the top of the fork dropouts
Holding the QR lever in the ‘Adjust’ position with your right hand, tighten the tension-adjusting nut with your left hand until it is finger-tight against the fork dropout
Push the wheel firmly to the top of the slots in the fork dropouts, and at the same time, centre the wheel rim in the fork
Move the QR lever into the ‘Closed’ position. The lever should be parallel to the fork blade and curved toward the wheel
To apply enough clamping force, you should wrap your fingers around the fork blade for leverage, and the lever should leave a clear imprint in the palm of your hand
Note: If the lever cannot be pushed all the way to a position parallel to the fork blade, return the lever to the ‘Open’ position. Then turn the tension-adjusting nut anti-clockwise a quarter turn and try tightening the lever.
Spin the wheel to make sure that it is centred in the frame and clears the brake pads; then, squeeze the brake lever and make sure that the brakes are operating correctly
Warning: Securely clamping the wheel with a Quick Release retention device takes considerable force. If you can fully close the cam lever without wrapping your fingers around the fork blade for leverage, the lever does not leave a clear imprint in the palm of your hand, and the serrations on the wheel fastener do not emboss the surfaces of the dropouts, the tension is insufficient. Open the lever; turn the tension-adjusting nut clockwise a quarter turn; then try again.
Warning: Riding with an improperly secured wheel can allow the wheel to wobble or fall off the bike, which can cause serious injury or death.
Rear wheel
1. Remove old rear wheel
Shift the rear derailleur to high gear (the smallest, outermost rear sprocket)
On a derailleur gear system, pull the derailleur body back with your right hand
Move the quick-release lever to the OPEN position
Lift the rear wheel off the ground a few inches and remove it from the rear dropouts
Caution: Disc rotors have sharp edges, and both rotor and calliper can get very hot during use.
Caution: Make sure that the clamping action results in a completely secured wheel that embosses the surfaces of the dropouts.
Caution: Be careful not to damage the disc, calliper or brake pads when re-inserting the disc into the calliper. Never activate a disc brake’s control lever unless the disc is correctly inserted in the calliper.
2. Install the new rear wheel
Place chain on smallest sprocket; seat axle; clamp QR
Ensure the QR lever is in the ‘Open’ position. The lever should be on the side of the wheel opposite the derailleur and cassette sprockets
Make sure that the rear derailleur is still in its outermost, high gear position; then pull the derailleur body back with your right hand. Put the chain on top of the smallest cassette sprocket
Push the wheel firmly to the top of the slots in the dropouts, and at the same time, centre the wheel rim in the frame. Ensure that the axle seats firmly at the top of the fork dropouts
Move the QR lever into the ‘Closed’ position. The lever should now be parallel to the seat stay or chain stay and curved toward the wheel
To apply enough clamping force, you should wrap your fingers around the fork blade for leverage, and the lever should leave a clear imprint in the palm of your hand
Note: If the lever cannot be pushed all the way to a position parallel to the fork blade, return the lever to the ‘Open’ position. Then turn the tension-adjusting nut anti-clockwise a quarter turn and try tightening the lever.
