INTEGRA Series: The Balance Between Lightness and Strength
In the world of mountain bike racing, lightness and strength have always been a challenging balance.
Riders want nimble and responsive wheels without compromising reliability or impact resistance.
BTLOS INTEGRA X30 Carbon MTB Rims are designed for high-intensity XC, XCO, XCM, and XCC races, combining innovative structural concepts, precise layup techniques, and advanced material technology.
1. Optimized Fiber Continuity and Reinforced Spoke Interface
Traditional carbon rims often require post-production drilling for spoke holes, which can compromise fiber continuity and create stress concentration areas.
The INTEGRA X30 series features a Fiber-Continuous Spoke Hole Design, reinforced during the layup stage for continuous fiber alignment and even stress distribution.
- Tensile strength improved by approximately 15%
- Impact resistance increased by approximately 25%
- Fatigue life extended by over 30%
2. Bowl-Shaped Spoke Seat Platform
Carbon fibers around each spoke hole are molded into a concave shape, allowing the spoke nipple to nest naturally.
- Even spoke tension distribution
- Improved nipple alignment and assembly precision
- Enhanced long-term wheel stability
3. Multi-Layer Carbon Structure
Hybrid layup of Toray T700, T800, and T1100 fibers:
- T1100: High-stress zones for tensile strength
- T800: Structural rigidity and deformation resistance
- T700: Vibration absorption and crack resistance
Combined with a toughened epoxy resin system for impact absorption and controlled deformation.
4. Front-Rear Differentiated Design
- Front Rim 230±15g: Terrain compliance and control
- Rear Rim 270±15g: Torque transfer and support
Weight Configurations:
- Lightweight (F&R 230g) → Max rider weight: 100kg
- Standard (F 230g / R 270g) → Max rider weight: 115kg
- High-strength (F&R 270g) → Max rider weight: 125kg
5. Low-Profile Rim Design: 22mm Height
- Improved long-distance comfort
- Increased tire grip and handling precision
- Reduced rider fatigue
