Instant Friction Optimization. Pure Greek Pine Formula.
The ξ /ksi/ cycling rim rosin blocks are engineered to instantly maximize the stopping power and locking bite of hydraulic trial rim brakes.
Many commercial rosins use synthetic additives or harsh chemical processing that can permanently contaminate your brake pads and leave a messy, destructive residue on your rims. We formulate our blocks using only pure, locally sourced Greek pine rosin blended with a precise ratio of natural organic beeswax. This premium organic blend delivers an uncompromising, instantaneous lock without degrading your hardware.
Key Advantages & Features
- Instant Braking Power: Gently rub the solid block directly onto the sidewalls of your ground aluminum rim to achieve an aggressive, non-slip friction layer.
- Fine-Tuned Performance: Easily customize your braking response. Apply a single light layer for a smooth, predictable grab, or layer it up for a full, unyielding wheel lock.
- Anti-Contamination Formula: The addition of raw Greek beeswax ensures the compound bites strictly on contact rather than glazing over your expensive polyurethane pad material.
- Perfect Synergy: Developed specifically to work hand-in-hand with our ξ /ksi/ cycling CNC Rim Brake Pads to unleash the most reliable bite possible in any weather condition.
How to Apply Rosin Blocks for Maximum Bite
- Prepare the Rim: For the absolute best results, apply our rosin blocks directly to freshly ground or textured aluminum rim braking surfaces.
- Apply Evenly: Lightly pull the rosin block along the circumference of the rim sidewall.
- Layer to Taste: Test the lever feel. If you need a stiffer, louder, and sharper bite, add another light layer until your wheel achieves an instant lock.
