World's biggest bike manufacturer branches out with updated Rev and two new aero lids.
After launching the Rev helmet last year, Giant has unveiled its first full line-up of road helmets. Alongside an updated Rev, there are two completely new models: the Rivet TT helmet, and the Rivet aero road helmet that we first spotted on the head of John Degenkolb at the Tour Down Under.
The Rivet is probably the most exciting project from the new range, and already has two monuments under its belt with Degenkolb’s victories in Milan-San Remo and Paris-Roubaix. Fitting into the new sub-genre of semi-aero helmets, the Rivet is designed to save you watts without having too much of a compromise when it comes to ventilation. Designed using Computational Fluid Dynamics (CFD), the helmet features three main and two side vents (or “Aerovent Ports” as Giant calls them) on the front of the helmet, and four on the rear to allow hot air to escape.
The helmet also features Giant’s Cinch Pro fit system, using a dial at the rear to adjust the helmet to the circumference of your head. The padding is antibacterial, with the venting also claiming to help transferring sweat off the top of your head.
Also new is the Rivet TT time trial helmet. As you’d expect, reducing aerodynamic drag is the number one priority with this lid. Like the standard Rivet, it has been designed using CFD, and features dimples which claim to stream airflow towards the rear. The Rivet TT is also bang up-to-date with its cut-off tail to make it aerodynamic whatever your position.
The Aerovent Ports are carried over from the Rivet, and Giant claiming that hte four air vents on the front of the helmet do not have a negative effect when it comes to drag.
Giant has also given the Rev helmet a slight revamp for 2015. Again developed using CFD, Giant claims that this helmet hits the scales at less than 250g – not super lightweight but certainly respectable, and the 21 vents makes it the lid of choice for Giant-Alpecin’s climbers.
The new Rev is already available, with the other two helmets expected to land in Giant retailers later this spring. UK pricing is still to be confirmed.
