As National Champion Tim Johnson prepares to defend his title this weekend in Bend, Oregon, Peloton takes a look at his Cannondale SuperX.
Johnson rides a 52-centimeter Cannondale SuperX, custom painted to signify his title as National Champion. The SuperX frameset is constructed from BallisTec carbon fiber. Developed for ballistic armor, it is ideal for cross or mountain bike frames due to its lightweight and impact resistance. The frame features a BB30 bottom bracket shell and 1.5-inch to 1.125-inch tapered headtube that houses an FSA Orbit IS CX headset. For 2010, the teams fork choice switches from an Easton EC90X to a Cannondale made carbon fork that is specifically designed for the SuperX. The SuperXs fork uses oversized straight blades and a tapered carbon steerer tube. The rear triangle features Cannondales SAVE rear stays. The SAVE stays use flattened cross-sections and a unique carbon layup to provide a small degree of vertical compliance. Overall the claimed weight for the SuperX frameset is 1400-grams over 400-grams lighter than the CAAD9 framesets the team was running last year.
The Cannondale-cyclocrossworld.com team is sponsored by SRAM, and is outfitted with Red components. To meet the performance demands of cyclocross the team deviates from Red in two areas. The first is the rear cassette, which is a Force level PG-1070. The team runs the cassettes because they features deeper gaps between the cogs than the one-piece machined PowerDome of Red.
The second deviation comes at the front derailleur. The derailleur is Red, with the titanium cage being replaced by a steel version. This is done to increase shifting precision in muddy conditions.
Transmission of power is delivered via 46/39 front chainrings mounted on 172.5-millimeter BB30 Red cranks mated to an 11-26 cassette. Gore derailleur cables keep everything shifting smoothly. As most cross racers in the States run Crankbrothers pedals, Johnson stays Euro with Shimano XTR.
A major change from last years team bike is the switch from TRP Euro X Magnesium brakes to Avid Shorty Ultimate brakes with SwissStop carbon pads. The Avid Shorty Ultimate are available in wide or narrow stance options, with Johnson choosing the latter.
The team continues to run Zipp 303s while Zipp provides Johnson with custom red, white and blue decals in honor of his 2009 national title. With the UCI cracking down on tire width in cyclocross, Johnsons Zipp 303s are wrapped in Dugast 32c tubular tires. Johnson has his choice of Dugast tires, depending on course and conditions.
The cockpit on Johnsons bike is all new for 2010 with Zipp expanding their sponsorship with their new line of alloy Service Course components. The aluminum parts are a departure for Zipp who is known for their high-end carbon wheels and parts. The Service Course SL stem is made using high-strength 3D-forged construction, 7075 aluminum, and features titanium TORX bolts.
The Service Course SL handlebar is constructed using Zipps proprietary ZTL-71 alloy and uses internal butting to increase stiffness and reduce weight. Johnson runs a 100-millimeter length stem and a 42-centimeter bar with a traditional shaped drop. The bars are wrapped in two-tone LizardSkins bar tape. The tape is made with DuraSoft Polymer that doesnt absorb water, and is available in 1.8 or 2.5-millimeter thickness. Johnson, who rarely uses gloves, runs the 2.5-millimeter version for a bit of comfort.
The Zipp Service Course seatpost uses a shaft and head that are 3D-forged from a single piece of 7075 aluminum, and is topped by a Prologo Nago Evo TR saddle.
