The Evolution of Primož Roglič’s Climbing Gear and Bike Setup

Primož Roglič, the Slovenian Grand Tour contender, has transformed his climbing gear and bike setup from a relatively standard foundation into one of the most meticulously optimized packages in professional cycling. His journey from a former ski jumper to a multiple Vuelta a España champion and Tour de France podium finisher is mirrored in the continuous refinement of his equipment. Today, every component—from frame aerodynamics to gear ratios, clothing layering, and power meter integration—is tuned for the unique demands of high‑mountain stages. This evolution reflects not only advances in cycling technology but also Roglič’s own physical and strategic growth, allowing him to excel in the steepest, most unpredictable terrains of the WorldTour.

The importance of a rider’s climbing setup cannot be overstated. On gradients exceeding 10%, every watt saved, every gram of weight reduced, and every aerodynamic advantage can translate into seconds that decide stage wins and overall classifications. Roglič’s approach has been methodical: he starts with a proven base platform—typically a top‑tier aero‑optimized road bike from his sponsor—and then customizes it with personal preferences for fit, gearing, and weight savings. Over the past decade, his gear has shifted from standard compact cranksets and mechanical shifting to electronic groupsets, power meters, and advanced wheelsets that balance aerodynamics with low weight. The result is a setup that gives him a competitive edge while maintaining the reliability required for three‑week tours.

This article explores the key phases of Roglič’s gear evolution, from his early professional years to his current race‑winning configuration. We examine the technological breakthroughs he adopted, the strategic decisions behind his equipment choices, and the measurable impact on his climbing performance. By understanding Roglič’s approach, readers gain insight into how elite cyclists integrate technology and personalization to conquer the mountains.

Early Career and Initial Setup

When Roglič turned professional in 2013 with Adria Mobil, his bike setup was relatively conventional for a neo‑pro. He rode a standard aluminum or entry‑level carbon frame, often from the team’s supplier, with a compact crankset (50/34T) and an 11‑speed cassette typically ranging from 11‑28 or 11‑30. His shifting was mechanical—Shimano Ultegra or 105 level—and his wheels were general‑purpose alloy or shallow carbon rims weighing around 1,500 grams per set. Clothing was functional but not specialized: standard bib shorts, a team jersey, and a simple gilet for descents.

At that stage, Roglič’s climbing technique was still developing. He relied on raw power and the ability to sustain high cadences, but his bike did not offer the fine‑tuned gearing or aerodynamic advantages that later become hallmarks of his setup. His primary focus was on adapting to the demands of professional racing, learning to conserve energy, and reading race dynamics. The bike was a tool, not yet a finely tuned instrument.

Initial Gear Specifications

  • Frame: Entry‑level carbon (e.g., Ridley or similar) with standard geometry, weight ~1.2 kg
  • Groupset: Mechanical Shimano Ultegra, 11‑speed, 50/34 crankset, 11‑28 cassette
  • Wheels: Aluminum box‑section rims, 1300g‑1500g per set
  • Cockpit: Standard alloy handlebars and stem, round profile
  • Clothing: Team‑supplied polyester jersey and shorts, minimal thermal regulation
  • Accessories: Basic cycling computer (speed, distance, cadence), no power meter

This setup was adequate for the lower‑tier races Roglič contested early in his career, but it lacked the specificity needed for WorldTour summit finishes. As he moved to Jumbo‑Visma (now Visma‑Lease a Bike) in 2016, the team’s technical support allowed for a step‑change in equipment quality and customization.

Technological Innovations and Upgrades

Roglič’s transition to a WorldTour team coincided with a rapid acceleration in bike technology. From 2016 onward, he adopted several key innovations that dramatically improved his climbing efficiency:

Electronic Shifting

The shift from mechanical to electronic groupsets—first Shimano Dura‑Ace Di2 (9070, then R9150, now R9250)—gave Roglič precise, instantaneous gear changes under high load. On steep pitches, where a mis‑shift could lose momentum, Di2 ensured consistent engagement. The semi‑wireless design of the latest 12‑speed version also reduced weight and improved aerodynamics by eliminating cables. Electronic shifting allowed him to focus entirely on cadence and power output without worrying about manual adjustments.

Ultralight Frame Materials

By 2018, Roglič was riding the Specialized S‑Works Tarmac SL6, a sub‑800g frame that combined stiffness with low weight. The SL7 and later SL8 (under 700g claimed) further reduced weight while improving aerodynamic tube shaping. The use of high‑modulus carbon fiber allowed the frame to remain stiff for power transfer yet compliant enough to dampen road vibrations, crucial for maintaining comfort on long climbs. Roglič also tested the Specialized Alpiniste, an ultra‑lightweight climbing bike, for some mountain stages, though his race bike is typically the all‑round Tarmac.

Wider Gear Ratios

As stages grew steeper and more selective, Roglič adopted a 52/36T chainset combined with an 11‑30 or even 11‑32 cassette. This provided a lower gear for the 15%‑plus gradients seen on climbs like the Angliru or Zoncolan, without sacrificing top‑end speed on shallower sections. The 36T inner ring with a 32T sprocket gives a gear of approximately 30‑33 inches, allowing him to spin an efficient 90‑100 rpm instead of grinding a heavy gear. This shift toward wider ratios is now common among top climbers, but Roglič was an early adopter within his team.

Power Meters and Data Integration

Since 2017, Roglič has used a Stages or SRM power meter integrated with his head unit (Wahoo ELEMNT or Garmin Edge). This data allows him and his sports directors to monitor wattage in real time, ensuring he never goes too deep early in a climb. By analyzing historical data from past ascents, Roglič can pace himself precisely, often producing steady power outputs that minimize fatigue. The power meter also informs gear selection: if his cadence drops below 70 rpm, he can shift to a lower gear to maintain torque efficiency.

Lightweight, Breathable Clothing

Roglič’s clothing evolved from standard team kit to specialized climbing apparel. His skinsuit‐style climbing jerseys (often from Assos or Castelli) use ultra‑lightweight, moisture‑wicking fabrics with micromesh panels for maximum ventilation. On high‑altitude descents, he often wears a thin windbloc gilet that can be stuffed into a pocket. His bib shorts feature minimal padding (to reduce bulk) and laser‑cut leg grippers to avoid pressure points. Sunglasses are often photochromic, adapting to changing light in tree‑lined mountain roads.

Wheels and Tires

For mountain stages, Roglič uses a combination of lightweight climbing wheels and moderate‑depth aero wheels. His go‑to climbing wheelset is the Ritchey WCS Apex 36 or similar low‑profile carbon rims (36mm depth) paired with 25mm or 28mm tires from Vittoria or Specialized. The wider tires (28mm at lower pressure) reduce rolling resistance and improve cornering grip on winding descent. For stages with a mix of flat and climbing, he may opt for 40‑45mm deep wheels that offer better aerodynamics without excessive weight penalty. The use of tubeless tires also reduces puncture risk and saves a few grams of weight.

Current Setup and Strategic Adjustments

As of the 2024 season, Roglič (now riding for Bora‑Hansgrohe) has evolved his setup further. His bike is the Specialized S‑Works Tarmac SL8, a critically acclaimed climbing machine that balances aerodynamics and weight. The frame weighs claimed 6.6kg complete (with pedals and bottle cages), putting it well within the UCI minimum of 6.8kg when fully built with deep wheels. Roglič’s position has also become more aggressive: he uses a lower handlebar drop and a longer stem to achieve a flatter back, reducing frontal area even on steep gradients.

Current Component Choices

  • Groupset: Shimano Dura‑Ace Di2 R9250, 12‑speed, 52/36T crankset, 11‑30 cassette (often with an 11‑32 for extreme stages)
  • Power Meter: Shimano Dura‑Ace dual‑sided (R9200‑P) or SRM Origin spider‑based
  • Wheels: Ritchey WCS Apex 36 for high mountains; Ritchey WCS Apex 45 for mixed parcours
  • Tires: Vittoria Corsa Pro or Specialized Turbo Cotton, 28mm tubeless, pressures 60‑65 psi rear, 65‑70 psi front
  • Cockpit: Ritchey WCS Classic carbon stem (-6°), Ritchey WCS Superlogic carbon handlebars (38cm width, compact drop)
  • Saddle: Fizik Arione 00 or Specialized S‑Works Power, lightweight carbon rails, minimal padding
  • Pedals: Speedplay Zero Aero (for 3‑degree freedom) or Look Keo Blade Carbon
  • Bottle Cages: Elite Leggero Carbon (single bottle for mountain stages to save weight)
  • Head Unit: Garmin Edge 1040 Solar (for navigation, power, and real‑time climb data)
  • Clothing: Assos Equipe RS Rapier Jersey (ultra‑light), Assos Tiburu bib shorts (low‑profile pad), Castelli Ros 2 Corso gloves, photochromic Oakley Radar EV Path glasses
  • Nutrition: Integrated cockpit storage (e.g., Silca Mattone or Bento box) for gels and bars during climbs to avoid reaching into pockets

Strategic Adjustments for Climbing Efficiency

Beyond the hardware, Roglič employs specific strategies to maximize his energy output on climbs:

Aerodynamic Positioning

Even on 8%+ gradients, Roglič maintains a low torso—forearms tucked, shoulders shrugged—to reduce drag. This position, sometimes called the “climbing aero tuck,” saves approximately 5‑10 watts compared to an upright stance. He practices this by spending time on a stationary trainer with aero bars, simulating mountain stages to build muscle memory.

Cadence Management

Roglič prefers a cadence of 85‑95 rpm on steady climbs and 75‑85 rpm on steep pitches. By using the widest gear ratios available, he avoids grinding a big gear, which saves his legs for later attacks. His power meter alerts him when cadence drops below 70 rpm, prompting an immediate shift.

Pacing with Power

Using historical power data from past climbs, Roglič and his sports director set a target wattage for each segment. Early in a climb, he holds back slightly (e.g., 5.5‑6.0 w/kg) to avoid going into oxygen debt. As the climb progresses and the gradient eases, he may increase output to 6.5‑7.0 w/kg for short surges. This disciplined approach was critical in his Vuelta victories, where he often gained time on descents or in the final kilometer by conserving energy earlier.

Lighting and Cooling

Roglič’s clothing choices incorporate advanced thermal regulation. On very hot mountain stages (e.g., southern Europe in July), he wears a white or light‑colored jersey to reflect sunlight, and an aero helmet with large vents (e.g., Specialized Evade 3 or Giro Aether) to keep his head cool. On cold descents above 2,000m, he adds a thin synthetic arm warmer and a gilet that can be removed quickly.

Bike Weight Reduction Tricks

For the most extreme summit finishes, Roglič’s team will strip the bike further: removing the bottle cage (if only one bottle needed), using an ultra‑light saddle (under 100g), fitting a single chainring (for time trials or mountain TTs), and even using lightweight titanium axles and bolts. These marginal gains together can save 200‑300g, which on a 10‑km climb at 8% translates to a savings of about 2‑3 seconds.

Impact on Performance

The continuous evolution of Roglič’s climbing gear and bike setup has directly contributed to his exceptional performance in high mountains. Since 2017, he has consistently been one of the best climbers in the WorldTour, winning mountain stages at the Vuelta, Tour, and Giro. Data from his winning rides shows that his power output on climbs has remained remarkably efficient, often producing 5.8‑6.2 w/kg for 30‑minute efforts, with a cadence that stays in the optimal range.

Specific examples highlight the impact:

  • 2020 Vuelta a España, Stage 17: Roglič attacked on the Alto de la Covatilla, using a combination of lightweight gear and aerodynamic positioning to drop his rivals. His SRM data showed consistent 6.0 w/kg for 20 minutes, with a cadence of 90 rpm, made possible by his 11‑30 cassette.
  • 2021 Tour de France, Stage 18: On the Col du Tourmalet, Roglič saved energy by riding a steady wattage early and then surging in the final 3km to gain time on overall contenders. His clothing choice—a lightweight jersey and windblock arm warmers—helped him manage temperature fluctuations.
  • 2023 Vuelta a España, Stage 13: On the steep final climb to Col du Tourmalet (yes, again!), Roglič used a 52/36 with 11‑32 cassette to maintain cadence above 80 rpm on 13% sections, while his rivals struggled with tight gearing.

Beyond isolated stages, Roglič’s overall climbing consistency has made him a formidable Grand Tour threat. His ability to recover from deep efforts and repeat performances day after day is partly attributable to the efficiency his gear provides. The reduced weight of his bike (under 7kg with pedals) means he expends less energy per pedal stroke, and the electronic shifting allows seamless gear changes even when fatigued.

Moreover, Roglič’s evolution has influenced the broader peloton. Many riders previously reluctant to adopt 52/36 or 11‑32 combinations now see them as standard for mountain stages. His use of power meters to pace climbs has been studied by teams seeking to optimize their own riders’ strategies. The integration of aerodynamic positions on climbs, once considered a marginal gain, is now common among GC contenders.
