For the fourth year running Road Bike Action is readying a team to compete in what is arguably the toughest & biggest gravel race on the calendar – the Dirty Kanza 200. In the coming days RBA editors Troy Templin, Jon Hornbeck and RBA contributor Janel Holcolmb will be heading to Emporia, Kansas to tackle the longest bike race any of them have ever attempted. Or, as Jon put it so succinctly when he realized that his day in the saddle would likely be in the 12-15 hour range, “Oh my God…that is so gnarly!”
For every year that we have participated in the DK, we have built up specific project bikes (below) in the attempt to test the latest gravel product as it has evolved. Following each participation, we have come away with more experience of what a proper gravel bike could/should be. Without a doubt it’s been this first person knowledge base that has enabled RBA to lead the way in gravel bike tech knowledge and expertise.
Three years prior to Gerard Vroomen rolling out his aero inspired 3T Exploro gravel bike last year, former RBA editor Neil Shirley got our Kanza ball rolling by jumping into the Specialized wind tunnel to maximize the aero performance of everything from his Crux race bike to his clothing and accessories. In his first year out in Kansas, Neil got rammed from behind and suffered a broken derailleur. After turning his bike into a singlespeed, Neil eventually limped in just over 15 hours after he started.
After spying Tim Johnson’s prototype race bike mounted with a Lefty fork in the pits at the 2015 cyclocross national championships, Zap figured that the 30mm of front wheel travel would be a boon for his attempt at the 100 mile half-pint race. This was the year of the big rain that created a four mile hike-a-bike section. It was from this bike that Cannondale took certain design cues to create the Slate and later, the revamped (and much improved) Super-X cross bike. Other than a bruised calf from the four miles of pedal slap while crying and pushing the bike, Zap was able to finish in 24th place on the Cannondale.
Furthering our effort to bring something new to Dirty Kanza each year, Neil hitched an exclusive ride aboard the much talked about Open UP gravel bike in 2016. Up front we mounted the Lauf gravel specific suspension fork that had 30mm of travel. Neil took full advantage of the Open’s asymmetrical chainstays to run 38mm Teravail tires mounted on Enve wheels, plus three bottle mounts the top tube storage box.
Although Zap had his special Di2 1x Shimano drivetrain(Ultegra shifters mated to an XT rear derailleur and 11-42 cogset) figured out in advance, it wasn’t until the Sea Otter Classic in mid-April that the frame came together thanks to Alchemy who supplied a carbon Hyas for the effort. Reynolds wheels, Specialized Trigger Pro tires, Pro aluminum stem & handlebars, a Thomson aluminum seatpost and ProLogo saddle, 140mm rotors, Lizard Skins bar tape, and Crank Bros. Candy pedals rounded out the accessory package. Of course if it wasn’t for his Wahoo Element GPS computer he would probably still be out their looking for the route to the finish.
This is what most bikes looked like in their post-Kanza profile. Each year it’s the combination of mud, head winds, heat or cold (depending), and notorious flint rock roads that provide the most gruelling challenge to finishing.
