If you’ve paid any attention to cycling gear over the past 25 years, you’re familiar with BOA® Fit Systems. BOA® has revolutionized how everyone from weekend road warriors to pros wear helmets and shoes, offering effortless, adaptable solutions for achieving the perfect fit and feel.
The evolution has been so impactful because BOA® continues to refine and update its technologies to fit the demands of modern cyclists and their gear. The company’s latest release sets the bar even higher: The BOA® Fit System Featuring FS2 – Dynamic 360™ brings an unmatched level of micro-adjustability to premium cycling helmets, including the new Specialized S-Works Evade 4.
Similar to the soft TX3 lace used across footwear, this BOA Fit System uses a TX1.2 lace. This low-profile, low-friction textile provides a soft, uniform fit that grants steadfast hold and security while reducing pressure. BOA® pairs the lace with its new FS2 dial, which rotates both clockwise and counterclockwise to deliver effortless submillimeter precision.
A yoke ladder with 11 adjustable positions assures pinpoint vertical fit, while the Helmet fit system’s forehead guide also helps ensure that the Evade 4 perfectly conforms to your head. Altogether, the BOA® Fit System Featuring FS2 – Dynamic 360™ provides a 6% stronger hold on the sides and front of your head and 40% finer adjustment resolution than traditional fit systems.

Those numbers are impressive, but the biggest testament to this BOA Fit System’s performance is the roster of elite cyclists who have embraced the Evade 4. This helmet is designed for racing at the highest levels, and pros like Remco Evenepoel—who won the 2026 Volta a la Comunitat Valenciana and finished third in the 2026 Liège-Bastogne-Liège race—and Demi Vollering, who took the 2026 Tour of Flanders and won the women’s Liège-Bastogne-Liège, are some of its high-profile wearers.
Other early adopters include track cycling star Lotte Kopecky, who finished first in the 2026 Milan-San Remo, and Matt Beers, a cross-country mountain biker and gravel specialist who won this year’s Cape Epic. The margins are incredibly fine at these races, and wearing a perfect-fitting helmet like the Evade 4 is one building block in a winning foundation. It also points to what BOA® and Specialized have achieved with this collaboration: a technological breakthrough that will benefit all cyclists, because who doesn’t want a perfect fit from head to toe?
BOA®’s journey started in Steamboat, Colorado, in 2001, disrupting snowboard boots by delivering superior fit, performance, and an enhanced experience for riders. Twenty-five years later, BOA® has now dialed in almost 300 million athletes and workers in over 80 countries, in partnership with leading sports and workwear brands globally.” —Shawn Neville, CEO of BOA® Technology
