Product details

Both an optical and a technical highlight are the new Ergotec Ahead stems Charisma and High-Charisma. The special forging technique allows the stems to be designed with a closed clamp at the upper part of the fork steerer. This gives the stem a less minimalist appearance and provides the bike with a more harmonious and cohesive design.

• Handlebar clamp: 31.8 mm
• Fork steerer diameter: 1 1/8 inches
• Angle: 20°
• Material type: Aluminum
• Intended use: City / Commuting
• Material details: Aluminum 6061 T6
• Design: Ahead.
