Specialised Showcases New S-Works Helmets at Tour de France

On the final day earlier than time trials on the Tour de France, groups are on their final seconds to fine-tune their kits. Specialised staff riders will select from a quiver of three up to date S-Works helmets.

The brand new lineup of Specialised S-Works helmets encompasses three acquainted fashions, all optimized for airflow and aerodynamics. Each focuses on a particular set of situations and driving disciplines.

To carry out the upgrades, Specialised rolled out fluid dynamics, finite factor evaluation, and testing on a number of continents together with aero trials in its “Win Tunnel.” Rider suggestions knowledgeable the method that finally produced the competition-focused Evade 3, light-weight Prevail 3, and speed-optimized TT5.

With out additional ado, listed here are the three fashions you’ll see on the noggins of Specialised riders.

S-Works Evade 3

When Specialised checked out updates the Evade 2 wanted, it discovered essentially the most room for progress in airflow. However fluid dynamics exams additionally confirmed its slight teardrop form made sense. Making aero features would require a redesign that didn’t compromise general kind issue.

Enlarged entrance vents primarily assist improve airflow. A rear diffuser, model new to the design, helps airflow as effectively but additionally helps aerodynamics on the prime again of the helmet. That space, based on Bikerumor, was one of many earlier design’s few draggy spots.

The whole lot from System 1 automobiles to buildings present in nature impressed the diffuser. The end result? The Evade 3 has 10% higher air flow than the Evade 2, and it maintains aero efficiency on the prime of the highway helmet class.

The Evade 3 (just like the Prevail 3) additionally provides MIPS Air Node expertise to decrease rotational impression pressure however reduce sacrifices in profile and breathability. MIPS Air Node integrates straight into the padding, behind a glossy low-friction layer.

With proprietary improvement, Specialised added perforations in the hunt for a stability between breathability, security efficiency, consolation, and weight financial savings.

S-Works Prevail 3

In search of to make the S-Works Prevail much more light-weight and ventilated with out compromising safety, Specialised took the design to the Win Tunnel. The all-around helmet nonetheless needed to carry out on lengthy climbs within the sizzling solar and maintain up in case of a worst-case state of affairs on a downhill.

Via testing, the staff discovered it might get rid of the bucket’s air-blocking foam “bridges” from the Prevail’s crown by introducing a slender carbon roll cage. The distinctive design additionally will increase the earlier unit’s ventilated floor space by a large 24.5%.

Woven aramid “cables” span the helmet and anchor to carbon fiber aspect panels. On impression, the so-called AirCage expertise works like a suspension bridge to diffuse pressure throughout the system.

The design not solely seems wild, nevertheless it also needs to work wonders to maintain riders cool, particularly at low speeds and huff-and-puff eventualities like massive climbs.

S-Works TT5

Per Bikerumor, Specialised admitted the TT4 fell behind the peloton of futuristic aero helmets. Now, it hopes the redesigned TT5 will assist it pull again even with the pack.

Riders Weigh In on Redesign

World-class riders like Remco Evenepoel and Kasper Asgreen of Fast-StepAlpha Vinyl consulted on the brand new, slippery design, spinning for hours within the Win Tunnel.

Fluid dynamics helped the staff draw the rear of the TT5 again over the rider’s shoulders in an try and create a slipstream. An inside sock seeks to assist maintain the helmet in the fitting place on the rider’s head and minimize down on rotational pressure on impression.

Evenepoel then put the screws to the TT5 in a time trial — to substantial impact. Specialised reported he hacked 26 seconds off a earlier 40K time trial; true, this 12 months’s Tour de France time trial solely covers 13K, however in a race the place the highest finisher normally wins by tenths of a second, nearly a half-minute represents a gulf.

Virginia Tech examined every helmet for security in its extremely revered amenities, and gave the Evade 3 and Prevail 3 a 5-star (highest) ranking. Every of those Specialised helmets is available in three sizes, varied colours, and retails for $300 MSRP.

Test them out on Specialised-sponsored riders at this 12 months’s Tour de France, which kicks off tomorrow in Copenhagen.
