Road Bike

Product

Overview

A road bike is a lightweight, drop-handlebar bicycle optimized for speed and efficiency on paved roads. This is a modern performance build: a carbon-fiber frame for stiffness-to-weight, electronic shifting for precise gear changes, hydraulic disc brakes for all-weather control, and a power meter so the rider can train to measured wattage. Aerodynamics, low weight, and an aggressive riding position all serve the single goal of going fast for less effort.

The chassis is a Carbon Frameset, a monocoque carbon front triangle bonded to a full-carbon fork, that carries two aerodynamic Carbon Wheel units. Propulsion comes from the Electronic Drivetrain, a wireless electronic groupset, and stopping from front and rear Hydraulic Disc Brake assemblies. The rider holds a carbon Cockpit and sits on a Saddle atop a carbon Carbon Seatpost.

How it works

Shifting is fully electronic and wireless. Buttons in each shift lever send a radio signal to a battery-powered servo derailleur, which steps the chain across the cassette with motor-driven precision and no cables to stretch or corrode. The crankset integrates a Power Meter: strain gauges bonded to the crank arms flex under pedaling load, and the bridge circuit converts that flex into a torque reading, multiplied by cadence to broadcast real-time power over ANT+/Bluetooth. Each Carbon Wheel runs a tubeless tire on a carbon rim, laced with bladed spokes to a ratchet freehub for low drag and fast engagement. The hydraulic Hydraulic Disc Brake system pushes fluid from the lever through a sealed hose to twin caliper pistons, clamping pads onto a center-lock rotor for consistent power wet or dry.
