📏 Handlebar Width Selection Guide

You can determine the correct handlebar width based on your shoulder width:

• 38 cm: Narrow shoulders (under 38 cm)
• 40 cm: Medium width / female riders
• 42 cm: Wide shoulders / male riders (average)
• 44 cm: Very wide shoulders / racers

Measurement is taken from the center-to-center distance between the two ends of the handlebar.

🔍 Frequently Asked Questions

What is the difference between 70 mm reach and 80 mm reach?
