GIRO Launches New Helmet For Progressive MTB Riders

5 August 2019  |  

Giro Sport Design, the cycling world’s design leader, today announced the helmet for the next generation of mountain bike riders, the Tyrant MIPS.

With full-cut coverage, MIPS Spherical, and two types of foam with differing densities, the Tyrant™ MIPS® serves up style to match the progression of riders like Josh Bryceland, Josh Lewis oder Veronique Sandler as they blaze new trails outside the racing tape.

“Racers are still racing, but so much of the real energy in mountain biking is now out playing in the woods -- building the ultimate lines and sessioning the best parts,” said Giro Marketing Director Dain Zaffke. “Tyrant is made for riders who are more likely to be wearing jeans than a number, but are still pushing boundaries with their riding. We wanted to give them a helmet that matches their style but still delivers the latest evolution in protection.”

At the heart of Tyrant lies MIPS Spherical, the latest iteration of the multi-directional impact protection system proven to reduce energy transmitted to the brain in certain impacts. Like a ball-and-socket joint, two layers of foam rotate around each other below a hardshell with in-mold polycarbonate Hardbody™ lower wrap.  One layer is EPS, which is well suited to dissipating energy from high-speed crashes. The other is a lower density EPP foam, with rebound characteristics designed to address low-speed, roll-around-in-the-dirt-type spills, like when a rider tumbles off a mis-timed footplant. The added coverage of a “full-cut” design brings confidence along with style, while Stack™ ventilation at the brow line and 14 vents combine with internal channeling to keep riders keep their cool. A new version of the RocLoc Air DH retention system locks everything in place, while adjustable cheek pads customize the fit.
