Excess Xls Alloy Rim 451x19.5mm 32h With Brake Surface

Excess XLS Alloy Rim 451x19.5mm 32h With Brake Surface

Product Overview

The Excess XLS is a lightweight BMX racing rim engineered with 6061 T6 aluminum and optimized aero profile. Featuring a machined brake track, angled nipple holes, and low-profile geometry, it delivers durable performance for v-brake racing applications with minimal 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
• Machined Brake Track — Precision-machined braking surface provides consistent pad contact and superior stopping power compared to standard anodized finishes
• Low-Profile Aero Geometry — Reduced rim height minimizes aerodynamic drag while maintaining spoke bed durability and structural integrity
• 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
• V-Brake Compatible — Rear rim design with machined brake surface delivers reliable mechanical braking performance
• 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
• Lightweight Performance — At 286g, minimal rim weight reduces rotating mass critical for competitive racing
