Pro Bike: Angela Naeth’s BH GC Aero In The Wind Tunnel

Angela Naeth came to the San Diego Low Speed Wind Tunnel with the Pearl Izumi Tri Team to have her position, apparel and equipment tested.

She rides the BH GC Aero.

She uses an XLab Torpedo cage to hold a standard round bottle on her downtube. Bottles rarely pop out of a frame mount, so she elects to use one of XLab's softer gripping cages rather than their super-burly versions designed for rear systems.

Naeth's unbranded rear hydration system mounts a single XLab Gorilla bottle cage, the company's sturdiest version.

Naeth races aboard the ISM Adamo Racing 2 saddle.

She uses an SRM power meter, integrated into a Shimano Dura-Ace crank with standard 53/39 chainrings.

Her SRM Power Control 7 computer is cleverly mounted using the small portion of steerer tube extending above her stem, since a water bottle occupies the space between her forearms.

Shimano Dura-Ace C75 tubular wheels.

Shimano Dura-Ace pedals. She rides the version with the metal body rather than the newer model with an injection molded carbon body.

Her power meter is wireless, but her Di2 components require a hardline connection. She routes the wire on the lower edge of her downtube.

This cockpit leaves the wires a bit jumbled and exposed instead of hiding them.

Unlike most frames, the GC Aero routes the rear derailleur cable through the top tube rather than the down tube. Not necessary on this bike, however.

More Shimano Dura-Ace equipment. She rides the outstanding 7900-series brake calipers.

Her rear C75 wheel is wrapped with Vittoria's sublimely supple Corsa EVO-CX tubular tire.

Her extensions were a little too long, so this tunnel tech took them to the saw and trimmed off a small ring of material.

Rather than using a standard extension, Naeth opts for Bontrager's down-then-up shape, pioneered by aerodynamicist John Cobb's now defunct Blackwell Racing brand.
