Bicycle Design Evolution & Trends

99 Spokes has detailed information on 96,541 bikes and we’re adding more every day. We painstakingly normalize each bike so we can connect features and components across different manufacturers; things like groupset, suspension travel, gearing ranges, and frame geometry. This is critical for providing an awesome search and comparison experience but it also leaves us with a rich dataset for reporting on bike trends. Listed below are a few interesting samples.

If you’re producing editorial content that could benefit from this kind of supporting data we’d love to hear from you. Give us a shout at hi@99spokes.com
