Shifting Techniques for Different Road Conditions

I. Flat Road Riding

• Acceleration Phase: Downshift 1 - 2 gears (e.g., from 17T to 19T) to increase torque. When the speed exceeds 30 km/h, upshift (from 19T to 15T) to reduce cadence.
• Cruising Phase: Maintain a cadence of 80 - 100 RPM. Opt for medium - gear combinations (e.g., 50/17) to reduce chain wear.
• Electronic Shifting Tip: Customize the rear derailleur button to “+2 gears” (such as in Campagnolo EPS) for a one - click upshift during sprints.

II. Climbing

• Long and Gentle Slopes: Switch to the small chainring and a medium - sized cassette cog (34/23) in advance. As the slope steepens, gradually downshift (from 23 to 25 to 28).
• Steep Slope Sprints: Use the small chainring and the largest cassette cog (34/34), and stand on the pedals for a powerful burst of effort.
• Taboo Operation: Avoid shifting the front derailleur on a steep slope to prevent the chain from falling off.

III. Downhill and High - speed Cruising

• Safe Gear Ratio: Use the large chainring and the smallest cassette cog (53/11) to reduce reliance on brakes. Pre - downshift to 13T before a turn to facilitate acceleration when exiting.
• Mechanical Shifting Caution: Anticipate turns in advance and avoid shifting while leaning the bike.
• Electronic Shifting Advantage: You can preset a “one - click downshift by 3 gears” function for emergencies.

IV. Headwind and Rolling Terrain

• Headwind Strategy: Use the small chainring and a 19T cassette cog. Maintain a high cadence (100 RPM) to reduce body movement and keep a low - drag posture.
• Rolling Terrain: Maintain the current gear ratio and adjust your pedaling force to control speed, reducing the energy loss caused by frequent shifting.

V. Corners and Technical Sections

• Before Entering a Corner: Downshift 1 - 2 gears (e.g., from 15T to 17T) in advance to make it easier to accelerate when exiting the corner.
• Slippery Roads: Choose a wider gear ratio (e.g., 34/25) to avoid chain skipping due to slippage.

VI. Extreme Road Conditions (Supplementary)

• Sand or Gravel Roads: Use the small chainring and a cassette cog larger than 23T. Maintain a low cadence (70 - 80 RPM) to maintain traction.
• Emergency Stops on High - speed Downhills: Switch to the small chainring and an 11T cassette cog in advance to use the gear ratio to assist in deceleration.

Key Principles

1. Anticipation First: Observe the road conditions 50 - 100 meters ahead and shift gears 1 - 2 seconds in advance (e.g., shift to the small chainring before climbing).
2. Avoid Cross - Chaining: Do not use combinations such as the small chainring with the small cassette cog (34/11) or the large chainring with the large cassette cog (53/28+).
3. Electronic Shifting Optimization: Customize buttons for “one - click front derailleur shifting” or “±2 - gear fine - tuning”.
