Revolutionize Your Ride: 55mm Deep, 26mm Wide Carbon Fiber Wheelset

Engineered for performance and precision, our 55mm deep carbon fiber wheelset delivers an exceptional balance of aerodynamic efficiency, lightweight responsiveness, and confident stability. The 26mm external rim width is meticulously designed to optimize tire profile, enhancing both aerodynamics and ride quality.

Product Features and Advantages

The 55mm deep profile slices through the air, significantly reducing drag for higher sustained speeds and improved efficiency, especially on flat to rolling terrain.

Enhanced Stability & Control: 

The wide 26mm external width creates a more stable, rounded tire profile, improving cornering grip, handling predictability, and crosswind stability compared to narrower rims.

Superior Ride Quality: 

The wider internal width (typically ~19-21mm) allows for lower tire pressures without sacrificing performance, resulting in increased comfort, better traction, and reduced rolling resistance on real-world roads.

Lightweight & Stiff: 

Constructed from high-modulus carbon fiber, these wheels offer an outstanding strength-to-weight ratio, ensuring rapid acceleration, precise power transfer, and excellent climbing capability.

Modern Tire Optimization: 

Perfectly paired with modern 23C-42C tires, this rim shape maximizes the benefits of larger volume tires, providing a faster, smoother, and more efficient ride.

Strict Quality Control:

KOBIKE do 100% tire pressure(150 PSI), flatness(＜0.2mm) and roundness(＜0.2mm) inspections before shipping, also offering 2 years warranty for our carbon rims.

Product Structure

Hidden Carbon Fiber Fish-Eye Design
Utilizes a hidden carbon fiber fish-eye design to reduce material thickness and achieve lightweight while maintaining strength at the spoke holes, enhancing overall stability and durability .

Spoke Hole Alignment Optimization
Optimizes spoke hole angles and spoke lacing patterns to ensure perfect contact between the rim and spoke nipples, eliminating spoke bends and improving force transmission .

Tubeless Compatibility
Supports tubeless installation, compatible with modern tire systems, enhancing air flow and durability .

Custom Spoke Hole Angles
Customizes spoke hole angles based on hub geometry to improve wheel stability and reduce maintenance needs .

High Roundness and Flatness
Achieves high roundness (±0.2mm) and flatness (±0.15mm) using high-modulus materials, ensuring comfort and stability during riding

Application Areas

Application areas for the R55X26TL carbon bicycle rim:

• The R55X26TL carbon wheelset redefines all-around performance, blending speed, control, and adaptability for cyclists who refuse to compromise—whether conquering climbs, carving corners, or chasing the pack.

• Road Racing & Endurance Events:
  The 55mm rim depth strikes an ideal balance between aerodynamic efficiency and lightweight agility. It excels in rolling terrain, long climbs, and endurance events like Gran Fondos, where responsiveness and acceleration matter as much as straight-line speed.

• Everyday Performance & Group Rides:
  Perfect for training and spirited group rides, the R55X26TL offers rapid acceleration, excellent speed retention, and predictable handling—making it a go-to choice for riders who demand consistent performance across diverse routes.

• All-Round Competition Wheelset:
  As a versatile "quiver-killer," the 55mm carbon rim combines aerodynamics, low weight, and stable handling. It performs exceptionally well in mixed-terrain races, criteriums, and stage events where courses feature flats, rolling hills, and technical sections.

• Sprints & Breakaways:
  With high torsional stiffness and reduced aerodynamic drag, these wheels deliver explosive power transfer and sustained momentum—ideal for launching attacks, bridging gaps, and finishing strong in high-speed sprints.
