The Box One Fixed Seat Post Clamp Kit (25.4mm, Gun Metal) is a high-performance, ultra-lightweight hardware component designed primarily for BMX racing frames using smaller diameter tubes.

Product Overview

• Box One Fixed Seat Clamp:
  • Precision machined from cold-forged 6061-T6 aluminum alloy, ensuring an optimized strength-to-weight ratio.
  • Equipped with premium, lightweight titanium hardware to secure the seat post firmly while minimizing weight.
  • Features an open-frame layout, finished with an anodized Gun Metal coating and laser-etched graphics.

Key Specifications

• Clamp Diameter: 25.4 mm (typically fits frames utilizing a 22.2 mm seat post).
• Weight: Exceptionally light at approximately 7 grams (0.2 ounces).
• Hardware: Single-bolt titanium fastening mechanism.
• Compatibility: Intended for specialized race frames. Always verify your frame's external seat tube diameter before purchasing, as a 25.4 mm clamp refers to the outer frame dimension, not the inner post size.
