1″ SEATPOST CLAMP 25.4MM VINTAGE SCHWINN STINGRAY LOWRIDER BICYCLE CRUISER BIKE

1" SEATPOST CLAMP 25.4MM VINTAGE SCHWINN STINGRAY LOWRIDER BICYCLE CRUISER BIKE 25.4mm / 1" ID Seat Post Clamps - Multiple Options Available Looking for the right seat post clamp for your bike? This is your one-stop shop for all our 25.4mm (1") inner diameter (ID) seat post clamps. This size is commonly used on vintage Schwinn, Stingray, Lowrider, some Cruiser models, and Old School BMX bikes. If your frame's seat tube has an outer diameter (OD) of 1 inch, this is the perfect clamp for you. Reference Note: For a 1" OD seat tube, your bike will likely require a 22.2mm seat post, or a vintage Schwinn 20.7mm seat post, depending on the thickness of the seat tube walls. Choose from a variety of colors and styles using the dropdown menu. You’re purchasing one clamp, but buying multiples saves you more! Important: Please read all information carefully, measure your bike’s dimensions, and choose the right option to avoid returns. Make a precise, informed decision and get exactly what you need—so you can ride happy! Copyright © 2024 Cycle Source. All rights reserved.
