Ultimate Road Bike Size Guide for Twitter Bikes

Choosing the right road bike size is essential for comfort, performance, and injury prevention. Twitter Bikes offers a diverse range of models, each with its own frame geometry designed to meet different rider needs.

In this guide, you'll find detailed sizing recommendations for all Twitter road models, covering:

Rider height
Inseam
Arm length
Reach & stack
Fit advice when you're between sizes

🧭 Why Geometry Matters in Bike Sizing

While height and inseam are important starting points, frame geometry—especially reach and stack—determines how a bike feels and fits.

Twitter’s lineup includes both race-oriented and endurance-focused models. That means two bikes labeled “Medium” may fit very differently depending on their geometry.
