Unbound 2021: The Men’s Overall 200-mile Winning Bike: Ian Boswell’s Specialized Diverge

ian boswell specialized diverge unbound 2021

Unbound for 2021, arguably the World’s best-known gravel race, was run and won yesterday in Emporia, Kansas. Riders from near and far trundle into town to test themselves on mileages of 25, 50, 100, 200, and the big one, the XL, at 350 miles.

The event is best known for the 200-mile distance; the biggest field, and over the past few years, the biggest names, have been drawn to the 200-mile race like a moth to a flame. That point aside, I have a first-hand appreciation for the riding experiences of the regular folks, those who aren’t professionals, former or otherwise, in the mid-pack and bringing up the rear of the race, versus those tearing it up at the front. I hope to be sharing a story or two from that perspective very soon.

Regardless of finishing times and places, I’ve always been interested in the bikes and technology that proliferate these events. Courtesy of the good folks at Vermont Social, I have intel on the Men’s 200-mile winning bike. I hope to feature the Women’s winning bike, the bike of Lauren De Cresenzo, as soon as possible (waiting on the data to arrive).

Keen-eyed readers will recognize the livery on this bike, a homage to the original and possibly first mixed-surface bike by a big-name manufacturer, the Specialized Rock Combo, released way back in 1989. Watch this space, I have a video coming soon that features a mostly original Specialized Rock Combo.

  1. The “Eagle Technology 500%” marking on the cassette is a tip that it is a 10-50.

  2. Awesome JOM, some corrections to the specs:

    Force AXS Shifters
    Eagle XX1 AXS Rear Derailleur “not” GX AXS
    Force AXS Crankset
    Quarq Power Meter with 44T Chain Ring
    Eagle XX1 Chain

    1. Many thanks, I appreciate the insightful help! I banged this out article out in a hurry on late Sunday morning with not a lot of fact-checking / scrutineering on my part.
