From design to delivery, we're your complete carbon gravel wheels solution:
Comprehensive rim design and manufacturing capabilities covering all gravel disciplines. Available rim depths: 35/40/45/50mm with internal widths of 21/23/25mm for optimal gravel tire support (35-50mm tires). Custom mold development completed in 45-60 days including full FEA structural analysis for rock impact resistance, CFD simulation for crosswind stability, and wind tunnel validation at 20-40km/h speeds typical in gravel racing. Each profile undergoes 3-month field testing across varied terrain including hardpack, loose gravel, and rocky sections. Design features include 4.5mm hookless bead walls for pinch flat protection, reinforced spoke beds for high-tension gravel builds (130kgf), and terrain-specific carbon layup schedules optimized for vibration damping. All molds manufactured using 5-axis CNC technology with ±0.02mm tolerance control for consistent tire seating and tubeless performance.
Streamlined production process optimized for medium-volume gravel wheelset manufacturing (10-200 sets) with 30-45 day delivery timeline. Each production run includes comprehensive documentation: ISO 9001 material certification for T800/T1000 carbon fiber, EN14781 impact test reports simulating rock strikes, individual spoke tension measurements (120-130kgf) for rough terrain stability, and detailed QC records. Manufacturing process features automated prepreg cutting with terrain-specific fiber orientations, CNC-controlled layup templates for consistent impact resistance, precision bladder molding (6-bar pressure/130°C cure) for optimal compaction in reinforced areas, and computerized resin content analysis ensuring durability in wet conditions. Production line maintains Class 10000 cleanroom standards for critical layup operations, essential for achieving void-free construction in impact-prone areas.
Comprehensive quality control system exceeding UCI gravel racing and ISO 4210 requirements. Stage 1: Impact resistance testing (1200J threshold) simulating rock strikes at 25km/h with high-speed camera analysis of rim deformation. Stage 2: Automated spoke tension measurement (120-130kgf) with electronic mapping for wheel stability on rough terrain. Stage 3: Tubeless compatibility verification including 6-bar pressure testing for 24 hours and dynamic air loss measurement (<0.5 bar/24hr) during simulated gravel impacts. Stage 4: Precision trueness verification (lateral/radial runout max 0.2mm) for consistent handling in technical sections. Stage 5: Surface finish inspection including mud-release coating verification, impact resistance testing at -20°C to +50°C, and UV stability testing (500-hour exposure) for all-weather durability. Additional testing includes loaded bikepacking simulation (100,000 cycles at 120% rated load).

Our shop has built countless wheelsets for gravel bikes. These wheels offer exceptional value - the hookless design makes tubeless setup a breeze, and customers love the wide range of customization options for their specific gravel riding needs.
Mike Roberts
Gravel Bike Shop Owner
I needed tough wheels for loaded bikepacking that could still feel fast on smoother sections. The custom layup schedule they recommended is perfect - stiff enough for climbing but compliant on rough terrain. 2000 miles in and still going strong!
