Alison Tetrick's 'Rock Combo' inspired Specialized Diverge for Unbound Gravel

Last month, Alison Tetrick raced a red and silver Specialized Diverge at the Gravel Locos race in Texas. But this weekend is the biggest gravel race in the world: Unbound Gravel

The monumental race calls for a special bike, and Specialized has certainly delivered one. Back in the 1980s, the brand debuted a bike called the Rock Combo, which was essentially a gravel bike before gravel was a thing. 

Tetrick will be racing a present-day Diverge with a unique Rock Combo-inspired paint job featuring a quintessentially '80s vibe that will bring Specialized's heritage from its headquarters in California to the plains of Kansas. 

Underneath the paint is a carbon frame, that is much more lightweight and comfortable than the old Rock Combo. A defining feature of the Diverge is the Future Shock, a 20mm suspension system integrated into the headset. 

The bike is equipped with Zipp Service Course parts, likely with 40cm bars and a 100mm stem, like Tetrick ran in Texas. 

The drivetrain is a mix of SRAM parts. A SRAM RED crank and brake/shift lever is combined with an XX1 Eagle AXS derailleur and cassette. 

Roval Terra wheels are combined with Specialized Pathfinder Pro tires, a popular combo on the Diverge. 

Purple Lezyne bottle cages add to the aesthetic of the bike.
