rudy-project-wing57-tt-triathlon-aero-bicycle-helmet

Triathlon helmets aren’t typically something I get super excited about. But the new Rudy Project Wing57 time trial helmet has some really innovative features that really stood out.
It’s a progression from the Wingspan they introduced a while back and was developed with aerodynamics guru John Cobb. At first glance, the biggest difference is the lack of an extended tail section. Instead, it uses a central fin on the exit port that has a magnetic extension to fit different rider back/neck shapes. It’s called the Vortex Killer, and it’s designed to reduce turbulence while helping pull more air through the helmet and balance out the high pressure zone typically created at the front of a helmet.

2012 Campagnolo EPS electronic shifting drivetrain for record and super record component groups

After two decades in development and many prototypes, Campagnolo’s EPS electronic component group has finally been made official, and they’ve launched not one but two complete groups.

Sure, they’re both at the very top end, but Record EPS and Super Record EPS get distinct electronic components, both for 11-speed only. The acronym stands for Electronic Power Shift, and the brains of the operation gets another one: DTI for Digital Tech Intelligence.

From what we’ve read Campagnolo says the electronics provide faster, more precise shifting than their mechanical groups, but that button feel offers a more mechanical tactile and audible impression than Shimano’s feathery and ninja-quiet Di2 buttons. It also claims to have better multi-shift capability than their mechanical systems, letting you run through the entire cassette by simply holding down the button. Rather than require multiple taps to shift multiple gears, its DTI measures how long you hold the button to determine how many gears it should shift, and it only takes a 1.5 second depression to run through the entire 11-speed cassette.
