INCOLOR RC-A Alcantara Carbon Saddle | 90g Ultra-Light Short-Nose Road Bike Saddle
INCOLOR RC-A Alcantara Carbon Road Bike Saddle
Built for riders who demand both race-level performance and premium comfort, the INCOLOR RC-A combines an ultra-light full-carbon structure with a premium Alcantara® contact surface and an ergonomic short-nose profile.
At approximately 90g, the RC-A delivers an exceptional strength-to-weight ratio while providing a more refined and secure riding feel than conventional lightweight racing saddles.
The premium Alcantara® surface offers a fine suede-like texture with high friction without excessive stickiness, helping improve stability during hard efforts while remaining comfortable on longer rides.
Premium Alcantara® Surface
The RC-A uses a premium Alcantara® contact surface, a material commonly found in high-end automotive interiors and premium performance products.
Compared with conventional saddle coverings, it offers:
- Fine suede-like tactile feel
- High friction without excessive stickiness
- Improved riding stability
- Reduced unwanted sliding
- Better breathability during longer rides
- Premium appearance and texture
The result is a saddle designed not only to perform, but also to provide a noticeably more refined contact experience.
Full Carbon Fiber Construction
The RC-A is built around a full carbon fiber base and carbon rail structure, creating a lightweight yet supportive platform for performance road cycling.
The carbon construction is engineered to provide:
- High strength
- Low overall weight
- Direct support
- Stable load distribution
- Reduced unnecessary structural mass
The support structure is designed to remain stable during long-distance riding and high-output efforts.
Ergonomic Central Cutout
A large central relief channel helps reduce pressure in sensitive contact areas.
The ergonomic open-center design helps:
- Reduce pressure concentration
- Improve comfort during aggressive road-bike positions
- Support sustained riding positions
- Improve ventilation around the contact area
This makes the RC-A particularly suitable for riders using modern aerodynamic road-bike positions.
Short-Nose Racing Geometry
The RC-A features a modern short-nose road saddle profile, designed for performance-oriented riding.
Its wide rear support area and shorter nose help support a forward, aerodynamic riding position while maintaining stability during harder efforts.
High-Grip, Stable Contact
The Alcantara® surface provides increased friction compared with conventional smooth saddle coverings.
This helps reduce unwanted movement during:
- Sprinting
- Climbing
- High-power efforts
- Aggressive riding positions
- Long-distance road riding
The material provides grip while maintaining a softer, more refined feel against cycling shorts.
Designed for Performance Riders
The RC-A is designed for riders who prioritize:
- Performance road cycling
- Lightweight bike builds
- Long-distance riding
- Competitive riding
- Premium component feel
- Stable saddle support
- Modern short-nose geometry
It is intended for riders who want more than a saddle that simply “works” — it combines low weight, stability, comfort and premium material quality.
