The Equipment and Gear That Help Primož Roglič Achieve Peak Performance

Primož Roglič’s journey from ski jumping World Cup winner to multiple Grand Tour champion is a rare story of biomechanical adaptation and technical precision. Racing for Bora–Hansgrohe in 2024, Roglič relies on a meticulously curated arsenal of technology—from his Specialized S-Works Tarmac SL8 to his SRAM Red AXS groupset—to dominate high-mountain summit finishes, decisive time trials, and chaotic transitional stages. The equipment he rides is not merely standard-issue WorldTour hardware; it is a highly personalized system optimized for his specific physiology, pedaling efficiency, and explosive riding style. This report provides a comprehensive breakdown of the hardware, apparel, and support tools that enable the Slovenian to perform at the sharp end of the peloton.

Frame Technology and Aerodynamic Platforms

The Specialized S-Works Tarmac SL8

Roglič’s primary weapon for road stages is the Specialized S-Works Tarmac SL8. This frame represents a synthesis of two prior lineages: the pure climbing weight of the Tarmac SL7 and the aerodynamic integration of the Venge. The SL8’s monocoque carbon construction uses Specialized’s Rider-First Engineered™ layup, which optimizes stiffness and compliance across all six frame sizes rather than simply scaling a single design. The raw frame weight sits around 6.8 kilograms with pedals and computer, hitting the UCI minimum, but the true innovation lies in the tube shaping. The truncated airfoil profiles, deeper down tube, and fully integrated cable routing reduce drag by approximately 16% compared to the SL7, according to Specialized’s wind tunnel data.

For stage races that demand climbing efficiency and descending confidence, this balance is critical. The bottom bracket area uses a massive 86mm wide shell to maximize lateral stiffness, translating Roglič’s power directly into forward momentum during standing starts on steep gradients. The seatpost, an S-Works SLR FACT carbon monocoque design, introduces controlled flex to absorb high-frequency road vibration without sacrificing aerodynamic efficiency. Roglič’s frame is custom-painted to match team graphics, but the underlying layup schedule is the same production-level schedule available to consumers—a testament to Specialized’s confidence in the manufacturing repeatability.

Time Trial Weapon: The S-Works Shiv TT

Time trial stages demand a radically different platform. Roglič pilots the Specialized S-Works Shiv TT, a pursuit-inspired platform with a deeply integrated hydration system and extreme aerofoil shaping. The frame’s truncated aerofoil profiles minimize drag across a wide range of yaw angles, while the integrated "Fuelcell" carries over 1.5 liters of fluid, allowing Roglič to stay in an aerodynamic position longer without reaching for a bottle. The UCI weight limit does not apply to track bikes, but on the road, the Shiv TT hovers just above the 6.8 kg limit when fitted with deep-section wheels and a power meter. The geometry is fine-tuned by his team’s bike fitters to match a moderately aggressive hip angle that sustains power output over 40-kilometer individual efforts.

Material Choices and Friction Reduction

Both frames use Specialized’s FACT (Functional Advanced Composite Technology) layup, combining 12K and 18K carbon fibers oriented to resist torsional flex under pedaling loads while absorbing road noise. Roglič’s builds frequently include ceramic bearings in the bottom bracket and derailleur pulley wheels from brands like CeramicSpeed or Kogel Bearings. These bearings reduce friction by up to 50% compared to standard steel bearings, saving a measurable but marginal number of watts—often 2-4 watts total—that compound over a three-week Grand Tour. Every component is scrutinized for weight, durability, and aerodynamic impact.

Drivetrain Precision and Power Analysis

SRAM Red eTap AXS Groupset

Roglič runs the SRAM Red eTap AXS wireless groupset, a 12-speed system that offers wider gear ranges and smoother shifting under load compared to its predecessor. The groupset uses SRAM’s proprietary AXS wireless protocol, ensuring near-instantaneous shifts even when the drivetrain is under maximum torque during a sprint or steep climb. The front derailleur utilizes a servo motor that adjusts itself based on chain angle and gear selection, preventing chain drops on rough pavé or technical gravel sections—a failure mode that can end a GC campaign in a single moment.

Roglič specifically uses a 2x drivetrain setup, typically pairing a 48/35 tooth chainring set with a 10-33 or 10-36 cassette. This defies the trend toward 1x systems seen in some one-day races and cyclocross events. The 2x layout provides tighter gear spacing, allowing Roglič to maintain an optimal cadence—typically between 85 and 100 rpm on climbs—without the large jumps inherent to 1x systems. The 10-tooth small cog on the cassette provides a high gear for descending above 60 km/h, while the 36-tooth climbing cog allows him to spin up grade gradients exceeding 20% on climbs like the Alto de l’Angliru. Mechanics swap cassettes and chains every 2-3 stage days to prevent wear-related shifting delays.

Integrated Quarq Power Meter

The Red AXS crankset incorporates a Quarq power meter directly into the spider. This unit measures left/right balance, torque effectiveness, and power phase—data that Roglič’s coach analyzes post-stage and during training to refine pacing strategy. The power meter is accurate to within ±1.5% and transmits data via both ANT+ and Bluetooth to his Wahoo ELEMNT BOLT V2 computer. In time trials, Roglič uses this data to hold a specific target wattage—often a percentage of his functional threshold power (FTP)—or to manage surges on rolling terrain. The SRAM AXS system also allows for satellite shift buttons mounted on brake levers or integrated into aerobar extensions, providing precise gear changes without moving hands away from the brake position.

Rolling Efficiency: Wheels and Tires

Zipp 454 NSW and 353 NSW Wheels

Bora–Hansgrohe is partnered with Zipp, and Roglič most often races on the Zipp 454 NSW or Zipp 353 NSW wheels depending on the terrain. The Zipp 454 NSW features a 58mm front and 77mm rear rim depth, utilizing Zipp’s Sawtooth™ design with Hyperfoil nodes. These nodes create a series of pressure vortices that stabilize the wheel in crosswinds—a critical factor when descending alpine passes at 80 km/h. The oscillation of the front wheel caused by gusting wind is significantly reduced compared to traditional deep-section rims. The rear wheel benefits from asymmetric rim geometry to balance spoke tension on the drivetrain side.

For high-mountain stages with extended climbing, Roglič switches to the Zipp 353 NSW, which uses a shallower 45mm profile and a lighter rim structure. Both wheels utilize Zipp’s Cognition V2 hubset, which features an axial clutch mechanism that disengages the ratchet when coasting. This reduces internal drag by 2-3 watts compared to conventional freehub designs, an advantage that is most pronounced during long descents where coasting time is high. The rims are hookless and designed specifically for tubeless tire mounting. This reduces weight and the risk of pinch flats, but also requires careful tire selection because not all tires are compatible with hookless rim beds.

Tire Selection and Pressure Strategy

Roglič uses Specialized’s S-Works Turbo RapidAir tires, available in either 26mm or 28mm widths. The 26mm variant is reserved for smooth, non-technical road surfaces where aerodynamic drag is the primary concern. The 28mm variant provides increased volume and lower pressure capability, which translates to greater comfort and reduced rolling resistance over rough roads. The RapidAir casing uses a 220 threads-per-inch (TPI) cotton-like construction reminiscent of traditional tubulars, producing a suppleness that conforms to road irregularities. The GRIPTON® compound provides reliable traction in both dry and wet conditions, reducing the likelihood of cornering crashes in high-speed technical descents.

Roglič runs front tire pressure around 25-28 psi and rear pressure around 28-32 psi, depending on road surface quality and stage length. These pressures are measured with a digital gauge before every stage, and his mechanics will switch to Vittoria Corsa Control tires on stages with particularly technical descents or wet roads, sacrificing some rolling resistance for improved grip. All tires are set up tubeless with latex sealant to seal small punctures instantly.

Contact Points for Power and Control

Specialized S-Works Aerofly Handlebars

Roglič rides the Specialized S-Works Aerofly II handlebars, which feature an aerodynamic D-shaped top section that gradually transitions into a compact drop geometry (125mm drop, 80mm reach). The flattened top section reduces frontal area when riding on the hoods, which is Roglič’s default position for climbing and steady-state pacing. The bars are monocoque carbon construction weighing approximately 220 grams in a 42cm width. Internal cable routing exits through the stem faceplate, maintaining a clean front profile that is essential for aerodynamic performance. The shallow drop allows him to maintain a powerful position on the bars while still enabling easy access to the brake levers for short-finger braking.

The stem is a Specialized S-Works SL, available in lengths from 80mm to 140mm. Roglič’s fit uses a 120mm stem with a 6° rise, adjusted to a -17° angle for a moderately aggressive upper body position. The combination of stem length and bar reach defines his torso angle, which balances aerodynamic drag reduction with the ability to produce sustained power. Bike fitters on the Bora–Hansgrohe staff regularly re-evaluate his position using motion capture and pressure mapping on a static bike, adjusting stack height by adding or removing headset spacers.

3D-Printed Saddle Technology

The saddle is a pivotal contact point, and Roglič uses the Specialized Romin Evo Pro with Mirror technology. This saddle features a 3D-printed carbon lattice matrix designed to provide variable density support across the entire saddle surface. The lattice structure consists of thousands of individual struts, each tuned to a specific spring rate based on the load profile predicted from pressure mapping during a professional bike fit session. The result is a saddle that offers firm support for the sit bones while softening the nose and sides to reduce soft-tissue compression during hours of seated climbing. The carbon rails weigh approximately 180 grams, making it one of the lightest performance saddles on the market.

Aerodynamic Apparel and Protective Gear

Race Suit and Helmet Integration

During time trials, Roglič wears the Specialized S-Works Evade Aero Race Suit, a one-piece skinsuit with dimpled fabric panels on the sleeves and a smooth, tightly woven back panel. The fabric reduces skin friction drag by 7-10% compared to a standard two-piece kit, according to Specialized wind tunnel tests. The suit includes a small rear pocket for a race radio and a hidden zipper for improved airflow. In road races, the standard team kit—SRAM branding, Bora–Hansgrohe colors—is also designed for aerodynamic optimization. Jerseys feature aero-elastic sleeves and a tight torso cut to reduce flapping at speed. Shorts use a high-compression leg gripper with silicone banding to keep hems in place against the air flow.

Helmet selection follows a similar logic. For road stages, Roglič wears the Specialized S-Works Evade 3, a ventilated road helmet that balances cooling with wind-tunnel-developed aerodynamics. The helmet features a MIPS SL (low-friction liner) system designed to reduce rotational forces during an angled impact, which is a significant cause of concussive injuries in cycling. For time trials, he switches to the S-Works TT helmet, a long-tailed aeroshell that covers the back of the head and integrates smoothly with the shoulders when in the aero position. The TT helmet includes a visor that seals against wind disturbance and reduces ocular drag. Both helmets weigh approximately 250 grams in medium size.

Footwear and Pedaling Interface

Roglič uses Specialized S-Works Ares shoes, featuring a stiff FACT powerline carbon sole (stiffness index 15 out of 15) and a heat-moldable upper made from Dyneema and synthetic leather. The BOA Li2 dial system allows for micro-adjustments during a race, and the upper wraps the foot securely without creating pressure points. After a heat molding process specific to his foot shape, the shoes become custom-fitted. The Look Keo Blade Carbon pedals provide a 13.5mm stack height and wide cleat retention platform, ensuring efficient power transfer from shoe to crank. The engagement click of the Look pedals is notably audible, providing positive feedback while remaining easy to clip out during high-pressure moments in a sprint finish or technical descent.

Roglič typically uses zero-degree float cleats (Look Keo Grip Cleats), which lock the foot in a fixed rotational position relative to the pedal. This minimizes energy wasted on lateral movement and is consistent with biomechanical fitting that seeks to align the knee over the pedal spindle. He uses Shimano Dura-Ace PD-R9100 pedals and cleats, which provide a wide platform for optimal power transfer.

The Support Ecosystem: Training, Nutrition, and Recovery

Indoor Training and Data Integration

Outside of race days, Roglič builds his baseline fitness on the Wahoo KICKR Gen 2 smart trainer. The KICKR uses a direct-drive mechanism, eliminating the need for a rear wheel and providing accurate power measurement within an estimated ±1% accuracy. It supports gradients up to 20% and auto-adjusts resistance instantly during structured training via ERG mode. Roglič controls the trainer and records data using a Wahoo ELEMNT BOLT V2 computer, which also displays real-time power, heart rate, and cadence from his SRAM AXS sensors. The trainer integrates with training software such as TrainingPeaks or Zwift, though Roglič prefers pre-programmed interval files that precisely dictate the workout for the day.

On-Bike and Off-Bike Nutrition

Nutrition is approached with the same scientific rigor as equipment selection. Roglič’s team uses sweat sodium loss testing, often performed during pre-season training camps, to customize hydration and electrolyte replacement strategies. On the bike, he carries two Specialized Purist water bottles (MoFlo valve for high flow) and integrates a BT (Bentley) bottle in the Shiv’s frame triangle for time trial fueling. His daily intake during mountain stages targets approximately 90-120 grams of carbohydrate per hour, primarily sourced from Precision Hydration and SiS GO FAR powder mixes. Gels from Maurten provide concentrated carbohydrate without the need for water, and solid food in the form of Naak bars or homemade rice cakes offers protein and fat to sustain energy on long mountain transfers.

Immediately after each stage, Roglič consumes a recovery drink containing a 3:1 or 4:1 ratio of carbohydrate to protein to replenish muscle glycogen stores quickly. His team’s bus is equipped with a portable kitchen and a chef specializing in race nutrition, ensuring meals meet caloric demands without upsetting digestion.

Recovery and Sleep Monitoring

Recovery is not passive; it requires active intervention. Roglič uses NormaTec Pulse 2.0 compression boots, which use sequential pneumatic massage to flush metabolic waste from the legs after intense efforts. A Theragun from Hyperice provides deep tissue massage targeting the quadriceps, hamstrings, and glutes. These tools are used on the team bus immediately following a stage and repeated throughout the evening during massage sessions with a dedicated seo therapist. Sleep is tracked via an Oura ring, which monitors sleep stages, heart rate variability (HRV), and body temperature. This data is analyzed to adjust training load and recovery protocols. Compression garments from 2XU and Assos are worn during travel and post-stage to reduce swelling and aid circulation.

When available, hyperbaric oxygen chambers and cryotherapy sessions are used during Grand Tour rest days to accelerate recovery from muscle damage. Pneumatic compression boots and electric muscle stimulators (EMS) are also used to maintain neuromuscular activation during periods of high fatigue.

Building the Collective Advantage

Primož Roglič’s success on the Grand Tour stage cannot be attributed to any single component or training method. It is the collective product of a meticulously engineered ecosystem: frames designed to optimize aerodynamics without sacrificing climbing ability, drivetrains selected for precise ratio spacing, wheels tuned for stability in crosswinds, and a recovery system that allows the body to endure the cumulative load of three weeks of racing. Every watt saved through ceramic bearings, every gram of tire pressure adjusted for road surface, and every gram of drag reduced by aero clothing contributes to the margin between victory and defeat at the highest level of professional cycling. Understanding this integration of hardware, data, and human performance provides insight into how modern athletes push the boundaries of what is physically possible.
