EXCESS XLS ALLOY RIM 406X28MM 36H NO BRAKE SURFACE

Product Overview

The EXCESS XLS is a 20" double-wall aluminum rim designed for BMX bikes using disc brakes or running brakeless. Built from 6061-T6 aluminum with a low-profile aero shape 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
• 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)
• Brakeless surface profile – No machined or textured brake track, designed specifically for disc brake or brakeless setups
• 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 with disc brake mounts or riders running brakeless. 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 riders building or upgrading BMX wheelsets who use disc brakes or prefer no brakes. 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 provides 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 rim brake setups—the brakeless surface profile will not provide adequate braking performance with caliper, U-brakes, or V-brakes.

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.

Disc Braking Compatible - Designed to be used as a front rim or a rear rim when using a disc brake.
