Specialized Diverge STR Expert.
30mm of rear suspension travel hidden in the seat tube delivers comfort without traditional linkage weight or complexity.
The Verdict.
Gavler Meta-Score
“The Diverge STR is the gravel bike that made roadies reconsider what drop-bar bikes can handle. The hidden rear suspension is engineering brilliance — 30mm of travel that disappears on smooth roads and activates exactly when you need it. For long gravel events on rough terrain, nothing else comes close to this level of comfort without a rear shock.”
