Overview
The Specialized CruX is a cyclocross and gravel bike model. The author uses their own CruX to illustrate the impact of drivetrain choice on tire clearance.
Role in this knowledge base
Used as an example to demonstrate how a 1x drivetrain can allow for greater tire clearance compared to a 2x setup on the same frame.
Key facts
- On the author’s Specialized CruX, a 2x configuration limits tire clearance to approximately 43-44mm, whereas a 1x setup could accommodate up to 47mm or more.
