With winter sweeping across North America, Team Maxxis-Shimano is settling into its first season on the US Pro Cyclocross Tour. We tracked down Danny Summerhill and his Parlee Z-ZERO XD for a bike check before he heads off to the Cincinnati Cyclocross Festival over Halloween weekend. Summerhill is fresh off a resounding win at the US Open of Cyclocross in Boulder, Colorado, and will be looking to take that momentum into the later half of the season. With the conditions now changing from dry races to the muddy later season events, bike set-up becomes ever more crucial. Read on to take a look at the details of Danny’s ride.
The Parlee Z-Zero XD frame is built from the ground up to be a race winner. Danny’s bike, hand built in Beverly, MA, is unique in every aspect. From the layup schedule of the carbon fiber to the tubing sizes and geometry, the bike was made to fit just one rider, an undeniable advantage when pushing one’s body to the absolute limit in a race. The skilled builders at Parlee pride themselves on their attention to detail, and Summerhill is happy with the quality build, “The bike fits like nothing else. It was so easy to transition to the Parlee because their experience with fitting and geometry is so advanced.”

With tight and often off-camber turns on varying, loose terrain, the sport of cyclocross is all about traction. Summerhill has been riding on Maxxis tires all summer with the UnitedHealthcare Pro Cycling Team, so it wasn’t a difficult transition into cross season, “tires make a huge difference in racing. Having a choice of tires is so important, and the guys at Maxxis really value our feedback.” As Maxxis designs new cross-specific treads, Summerhill and his Maxxis-Shimano teammates will be an integral part of the development process. Currently, Danny is training and racing on the Maxxis Raze tires with great consistency and success.
With no cables to contaminate with mud or dust, the Shimano Dura Ace Di2 groupset has proven itself to be reliable and easy to maintain during the cyclocross season, offering up crisp, reliable shifts regardless of the conditions. Utilizing the Dura Ace Di2 groupset, Summerhill’s bike is set up with a double chainset and an 11-28 tooth cassette, giving an extremely wide variety of gears. The gear range is important for the ever-changing conditions found on modern cyclocross courses, and provides the high-end speed needed for make-or-break sprint finishes. Combined with bar top remote shifters on his PRO Components handlebar, a feature only available with Shimano Di2 drivetrains, Summerhill has a range of hand positions to utilize while staying in complete control. The Dura Ace crankset is running on Kogel Bearings’ renowned bottom brackets, which utilize high-quality bearing and seals to withstand a season of racing in the elements, and the constant washing required. The custom blue offering on Summerhill’s Kogel bottom bracket is an easy way for Danny to keep track of his bikes and further stand out from the crowd. For the ultimate in braking power and modulation in any condition, Summerhill and the team use hydraulic disc braking systems from Shimano. The brakes have been a revelation for the riders, “The power and control is incredible. With just one or two fingers, you can quickly reduce your speed, allowing me to dive into corners faster and brake later with confidence.”
Always focused on performance, Danny is tracking his racing and training with the industry’s most accurate and comprehensive on-bike data system: Pioneer Power Meters. With unmatched accuracy and high-definition data output, the Pioneer power meter is able to give accurate recordings during technical races and all weather conditions. The robust power meters and head units can survive a full season and racing and training, even in the worst weather conditions.
