Captain America at the Tour of California

18 May

 

American Dave Zabriskie of the Garmin-Barracuda team was the fastest man against the clock on Thursday’s Stage 5 of the Tour of California, winning the race’s only time trial around Bakersfield.

 
Zabriskie covered the 18.4-mile (29.7-kilometer) course in 35 minutes and 59 seconds, with an average speed of 30.7 miles per hour (49.5 kilometers per hour).

Zabriskie’s Time-Trial Weaponry

Garmin-Barracuda’s Dave Zabriskie used a commanding win on Stage 5 of the Amgen Tour of California to vault into the overall race lead. Here’s a look at the technology that helped get him across the line first. —Joe Lindsey

Aero Stopping Power

Magura’s RT8 hydraulic rim brake caliper features arms that follow the shape of the fork to help aerodynamics. The hydraulic fluid line runs into the back of the caliper, keeping it “clean” in the air as well. And while many TT bikes suffer from substandard braking, the powerful hydraulic calipers offer impressive stopping power.

Lever Management

Magura makes dedicated brake levers for the system, but as you’ll notice, there’s no built-in system for Shimano’s Di2 shifters. At the Giro d’Italia, Garmin mechanics cobbled a custom solution for Ryder Hesjedal, but in California mechanics haven’t had time for that retrofit yet.
 
 

Power Stash

The cover you see here sits just above the chainstays and hides an integrated cubby for a Shimano Di2 battery. There’s dedicated cable management inside the bike as well, to make it easier to set up.
 
 

UCI-Legal

Cervélo uses a clever interpretation of the International Cycling Union’s rules on tube gussets to sculpt a seat tube–top tube juncture that would normally be an illegal shape. Anything to make the bike faster.
 
 

Cooling Tactic

Garmin’s Castelli skinsuits have a special pouch in the center of the back. In WorldTour races where radio communication is allowed, it can hold the riders’ radio transmitters. But at races like the Tour of California time trial—held in 101-degree heat in Bakersfield—it’s handy for socks stuffed with crushed ice.
 
 

Captain America’s Lid

Garmin has a special non-production version of Giro’s TT helmets. This is Dave Zabriskie’s Captain America livery as he is the U.S. national time-trial champion. First used at the Tour de France team time trial last year, the helmets are far blunter than even the Advantage 2 time-trial helmets that most other Giro-sponsored teams wore. Garmin’s sports scientist, Robby Ketchell, says that the profile has better aerodynamics in windy conditions. One downside: zero ventilation.
 
 

Labor of Love of Speed

Time trial bikes require special care. Team mechanics spend hours tinkering with internal cable routing, machining custom mounts for everything from computers to batteries, and doing anything they can to make the bikes faster (like removing bottle cages used in course recon). Here, Garmin-Barracuda’s Alex Banyay goes over Zabriskie’s Cervélo P5 to ensure that everything is in perfect working order.
