EXCESS XLS ALLOY RIM 406X28MM 36H WITH BRAKE SURFACE

Product Overview

The EXCESS XLS is a 20" double-wall aluminum rim designed for BMX 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 20x1.50" or 20x1.75" tires on the standard 406mm bead diameter. The optimized internal geometry balances light weight with structural strength for BMX racing, park, and street use.

Key Features

• 406mm bead diameter – Standard 20" BMX sizing compatible with 20x1.50" and 20x1.75" 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
• Tubeless-ready bead lock system – Internal bead lock profile allows tubeless tire setup when used with tubeless valve, rim tape, and sealant (sold separately)
• Black anodized finish – Single-process hi-polished anodizing provides corrosion resistance and clean appearance

Compatibility and Ideal Use Cases

This rim is designed for standard 20" BMX frames using rim brakes—most commonly as a rear wheel with V-brakes, though it also works with U-brakes or caliper brakes. The 406mm bead diameter is the standard BMX size used across racing, park, and street bikes. The 36-hole drilling works with standard 36-spoke hubs in various lacing patterns including radial, 2-cross, and 3-cross.

Best suited for BMX riders who use rim brakes and want a lightweight, stiff wheelset with reliable braking performance. The machined brake track ensures consistent brake pad contact and modulation. The tubeless-ready design benefits riders looking to reduce rotational weight and gain puncture protection through sealant, though tubeless conversion requires additional components not included. The 28mm external width and 23.3mm internal width provide a stable platform for 1.50" to 1.75" tires commonly used in racing, park, and street riding. The angled spoke holes and low-profile design suit riders prioritizing wheel stiffness and aerodynamics. Not recommended for disc brake or brakeless setups—choose the brakeless surface version for those applications.

Tubeless Ready System - Our rims feature a Bead Lock System, needed for the rim to be Tubeless Ready. With the installation of additional items needed you can get the rim ready for tubeless set up, along with the usage of a tubeless specific tire. With a tubeless set up, you can lighten up your wheels, saveing rotational weight, as well as have a sealant inside your tubeless ready tire to help automatically repair small punctures.
Additional items needed to convert to a Tubeless system include Special Valve, Sealant Rim Tape, and Liquid sealer.

V-Braking Compatible - Designed to be used as a rear rim when using a V-brake.
