Learn what's in the Strider 12 Sport/Pro Parts Kit and how to replace the QR clamp, washers, and axles step by step. Keep your balance bike running smoothly.
Quick answer
The Strider 12 Sport/Pro Parts Kit gives you the replacement rubber washer, Quick-Release Clamp, axles, and hardware you need to refresh your bike's folding mechanism and wheel mounting.
When to use the parts kit
The kit is designed for routine maintenance after months of riding. The rubber washer and QR clamp can wear out over time, causing the handlebar to fold unexpectedly or the seatpost to slip. Replacing these parts restores a secure fit without buying a new bike.
If your Strider 12 Pro has the word 'STRIDER' on the front fork, you'll need a different Pro parts bag. Call customer service to confirm compatibility before ordering.
How to use the Strider 12 Sport Parts Kit
- 1. Remove the old QR clamp and washer: Open the QR lever fully and slide the old clamp off the handlebar post. Pull out the worn rubber washer from the clamp slot. Common mistake: forcing the lever shut before the washer is seated can strip the clamp threads. Check the old washer for cracks; if it's hard or brittle, replace it now.
- 2. Install the new rubber washer and QR clamp: Place the new washer into the groove on the clamp body, then slide the clamp onto the post. Tighten the QR lever until it clicks into the closed position with moderate hand pressure. Common mistake: overtightening can deform the washer and cause slipping. The lever should close firmly but not require excessive force.
- 3. Replace the axles and hardware: Remove the old axle from each wheel using a 5 mm Allen key (not included). Insert the new axle with the included flat washer on the inside and cup washer on the outside. Tighten to snug, then back off a quarter turn. Common mistake: using the cup washer on the inside can interfere with the fork clearance. Spin the wheel after tightening; it should rotate freely without wobble.
