Excess Xls Alloy Rim 451x19.5mm 32h No Brake Surface

Excess XLS Alloy Rim 451x19.5mm 32h No Brake Surface

Product Overview

The Excess XLS is a lightweight BMX racing rim engineered with 6061 T6 aluminum and optimized aero profile. Featuring brakeless surface geometry, angled nipple holes, and low-profile design, it delivers durable performance for disc brake applications with minimal rotating weight.

Key Features

• 6061 T6 Double-Wall Aluminum Construction — Premium aluminum with optimized internal geometry balances lightweight design and structural strength for reliable racing performance
• Brakeless Surface Profile — Smooth, continuous rim surface eliminates mechanical brake pad contact, reducing rolling resistance and maintaining clean aesthetics for disc brake setups
• Low-Profile Aero Geometry — Reduced rim height minimizes aerodynamic drag while maintaining spoke bed durability and structural integrity
• Disc Brake Compatible — Designed for use as front or rear rim when paired with disc brake systems, providing braking flexibility across frame types
• Angled Nipple Holes — Precision angle geometry optimizes spoke tension distribution and improves lateral rim rigidity without requiring specialized nipples
• 32-Hole Construction — Balanced spoke count provides adequate lateral stiffness while minimizing rotating weight compared to 36-hole alternatives
• Optimized Internal Geometry — Strategic internal profile reduces material in non-critical zones while maintaining strength where needed most
• Presta Valve Hole — Compatible with presta valves for precise tire pressure control and compatibility with high-pressure systems
• Anodized Finish — Durable black anodized or polished finish resists corrosion and weathering while maintaining aesthetic appeal
• Ultra-Lightweight Performance — At 264g, minimal rim weight reduces rotating mass critical for competitive racing
