The S-Works Diverge STR Fact 11r carbon frame is more compliant than any drop bar bike Specialized has ever made, yet adds just just 100 grams compared to the S-Works Diverge frame. Never have so few grams added so much capability. Climb it, race it, or load it down with bags and gear for the long haul, Diverge STR does it all faster and smoother without any excess baggage. A complete, 56cm front and rear suspended S-Works Diverge STR bike weighs in at 18.73lbs set up tubeless out of the box. Remember speed comes from more than just the lightest weight.

This is a design developed for absurd capability, and more capability means more confidence, more confidence means more rides, more rides, means more fun, and for Specialized all starts at the contact patch. Nothing unlocks capability like tire clearance and the numbers are generous: 47mm on a 700c wheel and 2.1” on 650b. Diverge STR is the most capable gravel bike Specialized has ever made, so it’s the most fun. The Diverge design team tossed status quo out the window to create and work with progressive gravel geometry that amplifies the confidence that Future Shock Technology delivers, which keeps whatever wise tires you run tires on the ground, delivering traction, grip and control- which when absorbed into a rider's consciousness results in more speed, consistently. Need more capability? Carrying over from the Diverge, the internal downtube SWAT™ compartment puts everything you need, right where you need it, not in your pockets weighing you down.

With a geometry that is very similar to the Diverge, the fit and setup on a Diverge STR are pretty straightforward for those transitioning from it and not too difficult coming from most gravel set-ups The only primary fit consideration that differs from other bikes is the saddle position. Specialized and Retül recommend the static saddle position to be 5-10mm forward and slightly angled down more from your normal position. With this setup, your riding position with the proper suspension sag will be consistent with a rigid bike.
