Recently, many top level triathletes have opted for traditional road shoes, choosing to compromise transition time for better on-course fit and feel. We set out to create the ultimate triathlon shoe by combining the performance of a traditional road shoe with the barefoot comfort and quick-entry of a purpose-built tri shoe. The result is the Tri Fly PRO, a premium podium-focused shoe designed for speed, comfort, and efficiency to make the most of race day. The upper is constructed from a combination of airy mesh and synthetic leather to maximize ventilation and support. We built this shoe on the same feather-light, ultra-stiff carbon sole as our flagship PRO Air road shoe, which also features ample sole venting for quick drying. The BOA® Fit System allows for precise two-way micro-adjustments while riding, eliminates hot spots, and creates a wide entry for rapid transitions.

Sharing key features like a unidirectional carbon plate, dual-zone Boa closure, and a seamless upper, the Torch 3.0 is an efficient, comfortable, and dependable performance shoe. - Body Geometry sole construction and footbeds are ergonomically designed and scientifically tested to boost power, increase efficiency, and reduce the chance of injury by optimizing hip, knee, and foot alignment. - Unidirectional Carbon sole engineered to be stiff, yet light with a large rubber heel and toe for off-the-bike traction. - Dual BOA Li2 dials for dual direction micro-adjustments and pop release - Seamless upper constructed from mesh, TPU, and with zonal reinforcement to maximize lockdown and comfort - Internal heel counter provides a supportive and secure heel fit - Three-bolt cleat pattern fits all major road pedals. - Approximate weight: 288g (1/2 pair, Size 42)

Innovative evolution The free aero RC bibshort is our top race short, which also means that it's insanely comfortable even if you never pin on a number. It's fair to say that we've been working on this short for the past 15 years. That's how long it's been since the original free aero race bibshort was first introduced, initially as our top-of-the-line race short. Since then it has won three Tours de France, three Giri d'Italia, one Vuelta, and San Remo, but it also became the best-selling product in the history of Castelli because simply put, this is the short that does everything well. The concept is quite simple: start with the best pad we know how to make, surround it with a supportive short with good muscle compression, and then remove everything else that's not absolutely necessary. You feel free thanks to the reduced number of panels and the reduced number of seams. In fact, the short portion has just 5 panels compared to 10 in the previous generation. You feel free because of further refinements to the Progetto X2 air seamless seat pad. The two densities of foam plus the gel pads provide progressive damping, while the separate skincare layer is soft and stretchy to move with your skin. You feel free thanks to the most minimal bibs you've ever seen in a short, including open-weave straps for maximum airflow. But we reinforced the yoke so the straps stay in place and made the mesh back narrow for coverage that is minimal yet just enough to hold the shorts in place. And the bib elegantly frames a convenient pocket at the center back. You feel free because this is the first high-end short that doesn't need any sort of gripper or elastic at the end of the leg to keep the leg in place. Getting this right meant 28 prototypes and our most extensive test program ever, and it results in the most comfortable leg ending we've ever made. The Forza 2 fabric has 32% lycra with a high modulus for exceptional muscle support and just the right amount of compression. There's reflective piping on the back. And all logos are either stitched or embossed for durability. - High-compression 215g Forza 2 fabric with 32% lycra content provides exceptional muscle support and compression - Progetto X2 air seamless seat pad is soft against the skin but well padded for long-distance comfort - Minimalist bib straps allow maximum airflow, while a reinforced yoke keeps the straps flat over the shoulders - Rear mesh pocket - 5-panel construction for reduced seams and less chafing - Sublimation-printed graphic and logos that will never peel, crack, or fade - Reflective piping on back of legs - Soft waistband with raw-cut edge panels for extra stretch and comfort - Raw-cut leg ending engineered to stay put without silicone grippers

Meet the all-new Propero 4 helmet—it brings the aero advantages of the S-Works Evade 3 together with the ventilation of S-Works Prevail 3, all with the comfort and confidence Specialized helmets are famous for, earning the highest 5-Star Virginia Tech® helmet rating. Every detail of the Propero 4 was created with our equation for speed in mind. Aerodynamics + Ventilation + Lightweight = Fast. AERODYNAMICS: With extensive testing in CFD and in our Win Tunnel, aerodynamics were at the forefront of the Propero 4 development. We took the aerodynamic leading edge from the S-Works Evade 3 and pulled it directly into the Propero 4—which helped it to be four watts, or 15 seconds over 40km, faster than our S-Works Prevail 3. VENTILATION: Drawing inspiration from our world-renowned S-Works Prevail 3, our goal was not merely to replicate but to elevate. Ventilation became a focal point in our quest for a well-balanced, aerodynamic, and ventilated helmet. We incorporated the rear-end design language of the S-Works Prevail 3 and introduced small 2mm offset micro-channels that create turbulence in the airflow throughout the helmet to help create a continuous, refreshing flow of air. ATTENTION TO DETAIL: Beyond just aerodynamics and ventilation, the Propero 4 represents meticulous attention to detail. We went the extra mile by incorporating cutting-edge technologies from our S-Works level helmets, like MIPS technology for confidence, and a fit system designed to deliver all-day comfort. The Propero 4 doesn't just meet expectations - Mips Evolve Solution is a low-friction layer that allows a sliding motion of 10 to 15mm in all directions. Studies indicate that this reduces some of the rotational forces transmitted to the brain during angled impacts. - Propero 4 earned the highest 5-Star Virginia Tech® Helmet Rating from internationally renowned Virginia Polytechnic Institute and State University. - FS3 Fit System & Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape, and helmet angle can be adjusted for compatibility with glasses. - Adjustable Tri-Fix web splitter combined with thin 10mm webbing for increased comfort. - Dedicated sunglass storage maintains a secure fit and keeps eyewear out of the way when needed. - Micro Channeling & large rear-end vents for increased ventilation. - S-Works Evade 3 front-end design language for enhanced Aerodynamics. - Precision, full-wrap polycarbonate shell for increased durability and premium finish
