Excess XLS Carbon Rim 507x30mm 36h No Brake Surface

Excess XLS Carbon Rim 507x30mm 36H – No Brake Surface

Product Overview

The Excess XLS Carbon is a professional-grade 3K weave carbon rim designed for 24" BMX wheels with brakeless surface profile. At 397g with low-profile aero design, it combines strength and rigidity with lightweight construction, featuring angled nipple holes and front-or-rear compatibility with disc brake systems.

Key Features

• 3K Carbon Weave – High-quality carbon fiber construction with consistent weave pattern for strength and durability
• Brakeless Aero Profile – Low-profile aerodynamic design optimized for speed without machined brake surface
• High-Gloss Finish – Water-applied stickers with shiny clear coating provide durable, professional appearance
• Angled Nipple Holes – Slightly angled spoke hole openings create more direct spoke-to-nipple angle for stronger, more rigid wheel builds
• 30mm Width – Wide rim profile provides excellent tire support and modern BMX geometry compatibility
• Presta Valve Compatible – Drilled for Presta valve stems; standard for modern BMX wheels
• Disc Brake Compatible – Designed for front or rear wheel use with hydraulic or mechanical disc brake systems
• Ultra-Lightweight – 397g weight provides significant rotational weight savings versus alloy alternatives
• 36-Spoke Drilling – Standard BMX spoke count for balanced strength and weight
• Front or Rear Compatible – Versatile brakeless design suitable for both wheel positions
• Professional Performance – Engineering optimized for racing and high-performance applications

Build Requirements & Compatibility

• Spoke Compatibility – Use with butted or bladed steel spokes; verify spoke length based on hub flange geometry (approximately 280–310mm range depending on hub)
• Spoke Tensioning – Use calibrated spoke tension meter; maximum 115 kgf spoke tension
• Lacing Patterns – Angled nipple holes support standard cross lacing; radial lacing not recommended
• Tire Compatibility – Designed for 24" BMX tires; verify tire bead diameter matches 507 ETRTO standard
• Valve Type – Presta valve compatible; verify tire valve type before assembly
• Hub Compatibility – Works with any 36-hole hub (front or rear); verify ERD and spoke hole count
• Brake Compatibility – Brakeless surface designed for disc brake systems; use as front or rear wheel with disc brakes
• Carbon Fiber Care – Handle carefully to avoid impact damage; carbon fiber can crack if struck hard

Compatibility & Ideal Use Cases

• Professional BMX racing – Optimized for competitive racing with brakeless aero profile
• Disc brake systems – Compatible with hydraulic and mechanical disc brakes on front or rear wheels
• Weight-optimized builds – 397g weight provides significant savings versus alloy alternatives
• High-performance racing – Professional-grade carbon construction for serious competitive riders
• Modern BMX geometry – 30mm width provides excellent tire support and contemporary frame compatibility
• Front and rear wheel options – Versatile design allows use in either position with disc brakes
• Speed-focused builds – Brakeless aero profile optimized for sustained speed and racing applications
• Experienced riders – Carbon fiber construction requires careful handling and knowledge of material properties

Important Notes

• Carbon fiber construction; handle carefully to avoid impact damage or cracking
