Parts Kit-Strider 12 Sport/Pro

The rubber washer on my old one had worn down to almost nothing, so this replacement set was exactly what I needed to get the bike feeling solid again. The clamp tightened down smoothly and the whole swap took me under five minutes.

The quick-release clamp clicks in securely and the washer has held up through a month of daily rides on our gravel path—no wobble at all. Fits the 12 Pro exactly as described, which saved me from buying a whole new bike over a $15 part.

The rubber washer seated perfectly on the first try, and the clamp's release lever snaps shut with a reassuring click that feels just like the original. My kid's been riding daily for two weeks now and nothing has loosened up, which is exactly what I needed after losing the old parts.
