Dave Zabriskie’s Cervélo R5 VWD Garmin-Barricuda team bike features a few custom modifications by mechanic Alex Banyay (Ben Delaney/BikeRadar)

Garmin-Barricuda’s time-trial ace David Zabriskie moved into
the leader’s jersey at the Amgen Tour of California
thanks to his skills
against the clock on the new Cervélo P5, but he’s racing the remainder of the
event on a Cervélo R5 RWD.

There are a few notable things about Zabriskie’s road rig:
custom frame modifications, and — as befits a champion time trialists —
time-trial chain rings and a time-trial saddle. Zabriskie also run a double
thickness of handlebar tape.

As Cervélo’s R series bikes do not come with internal
routing for Shimano Di2, Garmin-Barricuda mechanic Alex Banyay took matters
into his own hands, and drilled a hole in the top tube to run the wiring
through. (Don’t try this at home, kids — it voids your warranty).

Where the wiring comes out at the bottom bracket area,
Banyay took advantage of the existing hole in the frame for the front
derailleur cable to run the Di2 wire up to the front derilleur. Then he ran the
rear wire back to the rear derailleur, taping and zip-tying it down along the

Banyay also drilled mounting holes for the Di2 battery on
the bottom of the down tube.

Zabriskie is using Rotor’s aero time-trial chain rings and spider
cover, with a standard 53/39 configuration. Rotor general manager Kervin
Quinones said the TT rings are a little bit stiffer (and a little bit heavier)
than the regular road rings, and of course also offer a bit of an aero

The Rotor 3D+ cranks are mounted with Rotor’s version of the
PF30 bottom bracket, using ceramic bearings. The set-up features a lock ring
that preloads the bearings with a 2mm Allen key.
