EXCESS XLS CARBON RIM 406X32MM 36H NO BRAKE SURFACE

Product Overview

The EXCESS XLS Carbon is a 20" carbon fiber rim designed for BMX bikes using disc brakes or running brakeless. Constructed from 3K carbon weave with a high-gloss clear coat finish and angled spoke holes, this rim accommodates 20x1.50" or 20x1.75" tires on the standard 406mm bead diameter. The carbon construction delivers high strength and stiffness at a weight comparable to aluminum, with increased rim width for wider tire support.

Key Features

• 3K carbon fiber weave – Carbon construction provides high stiffness-to-weight ratio and vibration damping characteristics compared to aluminum
• Wide rim profile – 32mm external width and 25mm internal width support wider tires and improve stability at lower pressures
• 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 – 25mm rim height balances aerodynamics with structural strength for BMX applications
• 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
• High-gloss clear coat finish – Shiny clear coating over 3K weave with water decals protects carbon and provides visual depth

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. Note the 377.4mm ERD requires proper spoke length calculation—verify spoke length before ordering or building.

Best suited for riders building high-performance BMX wheelsets who use disc brakes or prefer no brakes and want the benefits of carbon fiber construction. The wider 32mm external width accommodates modern wider tires (1.75" to 2.0"+) for improved grip and stability. 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. Ideal for riders prioritizing wheel stiffness, responsiveness, and reduced rotational weight in racing, park, or street applications. Carbon rims require careful handling during installation and maintenance—overtightening spokes or improper brake pad contact can damage the rim. Not recommended for rim brake setups—the brakeless surface profile and carbon material are incompatible with rim 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.
