Giro Advantage 2 with Roc Loc 5

A time trial triathlon aero helmet has been proven to be one of the most aero dynamic upgrades a rider can take "advantage" of. Some studies have shown that the Giro Advantage 2 can not only equal but make a bigger difference than a set of aero wheels including a rear disc. That's pretty amazing considering that the Advantage 2 with the new ROC LOC 5 fit system is about a 10th of the price of most carbon wheel sets. With the new ROC LOC 5 "one handed" tension/release system for 2011 that is desined to be incredibly easy to use and work flawlessly with most eye protection, the ROC LOC 5 will simply make you happy. And fast to.

The body position on the bike is and always has been the number one determining factor when smashing through the wind. The Advantage 2 with Giro's attention to detail such as the 5 vents that channel air through the helmet to keep you cool is simply faster then any regular road helmet and arguably faster than an aero dynamic wheel set.

Suggested use: triathlon, time trial, ultra distance triathlon

*aero dynamics can not only make you faster but can save energy for the run*
