NESTO ALTERNA DISC | Aluminum Disc Road Bike Balancing Lightness and Safety
More direct riding pleasure. An aluminum disc road bike that combines lightness, rigidity, and stability at a high level.
Whether it's flowing along at speed or smoothly navigating corners, the NESTO ALTERNA DISC allows you to fully experience the exhilarating sensation unique to road bikes.
The frame, which adopts racing geometry, offers agile riding performance that responds faithfully to pedaling power. Furthermore, the added high rigidity from the front and rear thru-axles ensures a stable ride, even at high speeds and downhill.
The flat mount disc brakes provide stable braking power, unaffected by weather or road conditions. This highly complete aluminum road bike is suitable for a wide range of uses, from daily training to long rides and even first-time sport riding.
