EXCESS XLS ALLOY RIM 451X19.5MM 28H WITH BRAKE SURFACE

Product Overview

The EXCESS XLS is a 20" double-wall aluminum rim designed for mini BMX and cruiser bikes using rim brakes. Built from 6061-T6 aluminum with a low-profile aero shape, machined brake track, and angled spoke holes, this rim accommodates 20x1-1/8" or 20x1-3/8" tires on the 451mm bead diameter standard. The optimized internal geometry balances light weight with structural strength for mini BMX and cruiser applications.

Key Features

• 451mm bead diameter – Standard mini/cruiser sizing compatible with 20x1-1/8" and 20x1-3/8" tires
• Double-wall construction – 6061-T6 aluminum with optimized internal geometry distributes impact forces and resists denting
• Machined brake track – CNC-machined braking surface provides consistent, smooth contact for caliper, U-brake, or V-brake systems
• Angled nipple holes – Spoke holes drilled at an angle for more direct spoke alignment, improving spoke tension consistency and wheel stiffness
• Low-profile aero design – Reduced rim height lowers aerodynamic drag while maintaining strength
• 28-hole configuration – Lighter spoke count reduces overall wheel weight while maintaining adequate strength for mini/cruiser use
• Black anodized finish – Single-process polished anodizing provides corrosion resistance and clean appearance

Compatibility and Ideal Use Cases

This rim is designed for 20" mini BMX and cruiser frames using rim brakes—most commonly as a rear wheel with V-brakes, though it also works with U-brakes or caliper brakes. The 451mm bead diameter is the standard for mini/cruiser bikes, not the 406mm used on traditional BMX bikes—verify your frame and tire compatibility before ordering. The 28-hole drilling works with 28-spoke hubs in various lacing patterns.

Best suited for mini BMX and cruiser riders who use rim brakes and prioritize light weight. The machined brake track ensures consistent brake pad contact and modulation. The narrower 19.5mm external width and 14.6mm internal width are optimized for the slimmer 1-1/8" to 1-3/8" tires typical of mini and cruiser bikes. The 28-hole count and lighter overall weight suit riders within typical mini bike weight limits who ride park, street, or casual cruising. Not recommended for aggressive jumping, high-impact riding, or heavier riders who would benefit from a 32 or 36-hole rim. Not recommended for disc brake or brakeless setups—choose a brakeless surface version for those applications.
