Early Career and the Ski Jumping Foundation

Primož Roglič’s path to professional cycling was anything but conventional. Before he became a Grand Tour contender, he was a world-class ski jumper, competing at the highest level including the 2010 Winter Olympics. That background gave him an exceptional sense of body awareness, balance, and core strength. However, the transfer from ski jumping to cycling was not seamless. When he first joined the Adria Mobil team in 2013, his climbing pedal technique was raw and largely derived from endurance-based instincts rather than biomechanical efficiency. In those early years, Roglič rode with a notably upright posture on climbs, a common trait among cyclists who prioritize comfort and oxygen intake over aerodynamic drag and power transfer. His pedal stroke was dominated by a strong downward push, with relatively little engagement during the upstroke or through the dead spots at the top and bottom of the rotation. This technique, while sufficient for shorter climbs or less demanding races, became a liability as he stepped into the WorldTour with Jumbo-Visma (now Visma-Lease a Bike) in 2016.

The Search for a Circular Pedal Stroke

As Roglič transitioned from a promising neo-pro to a team leader, his coaches identified inefficiencies in his pedal biomechanics. The hallmark of a world-class climber is a circular pedal stroke that applies torque consistently throughout 360 degrees, minimizing dead spots and reducing muscular strain. Working with coaches like Louis Delahaye and later with performance analysts at the team’s training center in Den Bosch, Roglič undertook a deliberate overhaul of his technique. The primary change was moving from a primarily quads-dominant, mashing style to a smoother, more rounded motion. This involved consciously engaging the hamstrings and hip flexors during the upstroke, while maintaining power during the downstroke. The shift did not happen overnight; it required hundreds of hours of drills on stationary trainers with real-time feedback from crank-based power meters that measure pedaling smoothness (often called Pedal Force Effectiveness or PFE). Studies have shown that elite climbers often achieve a “dead spot” reduction of over 60% compared to recreational riders (TrainerRoad article on pedal stroke optimization). Roglič’s adaptation was particularly impressive because he retained his explosive power while gaining efficiency, a balance few riders achieve.

Key Biomechanical Adjustments

Several specific changes defined Roglič’s new pedal style. First, his ankle angle became more dynamic. Where he once kept his foot relatively flat, he now allows a slight dorsiflexion (toe-up) during the recovery phase and a plantarflexion (toe-down) through the power phase, effectively allowing the calf muscles to contribute more continuously. Second, his seat height was slightly lowered—by as little as 3–5 millimeters—to optimize the leverage angle for the gluteal muscles, which are more fatigue-resistant than the quadriceps. Third, his cleat position was shifted rearward on the shoe, a trend pioneered by some time-trial specialists, which reduces the effective pedal radius and encourages a smoother transition over the top of the stroke. These micro-adjustments, combined with a focus on hip stability (drawn directly from his ski jumping core strength), allowed Roglič to produce a higher average power at lower perceived exertion. The result was visible in time trial stages as well as mountain finishes.

Equipment Evolution: Clipless Pedals and Bike Fit

Roglič’s equipment choices mirror his technique evolution. He has long used Shimano pedals, switching to the Dura-Ace PD-R9100 series which offers a wide platform and low stack height, improving stability and power transfer. More critically, his shoe and cleat setup underwent constant refinement. The rearward cleat position mentioned above required specific shoe insoles and a customized arch support to prevent hot spots and maintain comfort over six-hour stages. His saddle fore-aft and tilt were also adjusted to allow a more aggressive forward tilt on steep gradients, enabling him to rotate the pelvis and engage the glutes maximally when the road pitches above 10%. The bike itself—first the Bianchi Oltre XR4, then the Cervélo R5 and later the Cervélo S5—was fitted with integrated power meters (Quarq or SRM) that provided real-time torque data. Roglič’s team also used pressure mapping insoles during training camps to visualize foot pressure distribution at different cadences. This data-driven approach allowed him to experiment with foot angle on the pedal—slight external rotation (duck-footed) on certain climbs to relieve knee strain, or a more parallel stance for maximal power transfer on longer ascents.

Dynamic Engagement: Subtle Adjustments on Steep Gradients

Perhaps the most sophisticated aspect of Roglič’s current technique is his ability to modulate his pedal engagement dynamically based on gradient, fatigue, and race situation. On moderate climbs (5–8%), he favors a steady, high-cadence spin (80–90 rpm) with a nearly circular stroke. As the gradient steepens above 10%, he shifts to a more powerful, lower-cadence style (65–75 rpm) where he employs a pronounced “ankling” motion—a rapid toe-down at the bottom of the stroke and a quick heel-drop at the top—to maintain torque without excessive muscular fatigue. This technique is particularly visible on the hairpins of the Alps or the Pyrenees, where Roglič often accelerates out of corners with a distinct punch. Additionally, he uses subtle shifts in lateral weight distribution: rocking the bike slightly side-to-side under heavy load to engage additional muscle fibers in the hips and lower back. This is not a wasted motion but a controlled rhythm that many top climbers like Chris Froome and, more recently, Jonas Vingegaard have mastered. Roglič’s version is slightly more economical, as he lifts the bike less dramatically than Froome but maintains a more consistent pedal force.

Standing vs. Seated Strategy

Roglič has also become known for his climbing stance transitions. Earlier in his career, he would stand up abruptly to accelerate, which often resulted in a jerky pedal stroke and momentary power loss. Now he uses a seamless transition: he rises from the saddle while maintaining a smooth pedal arc, the bike barely swaying, and then returns to the saddle without interrupting his breathing rhythm. This skill is especially valuable during long mountain stages where repeated accelerations can drain energy reserves. Data from the 2023 Tour de France (Cyclingnews analysis of Roglič’s climbing) shows that Roglič’s standing-to-seated transitions were among the smoothest in the peloton, with less than a 0.5% variation in speed during the shift. This efficiency partly explains his ability to follow accelerations from lighter climbers like Tadej Pogačar without overexerting himself.

Data-Driven Refinement: The Role of Technology

The modern climbing pedal technique is inseparable from data analysis. Roglič’s team employs a combination of instrumented cranks, inertial measurement units (IMUs) on the pedals, and video motion capture during specific training blocks. One of the key metrics used is “torque effectiveness” (TE), which measures the ratio of positive to negative torque over a pedal cycle. A perfect circular stroke would yield a TE of 100%, but in practice even elite cyclists achieve around 60–75% due to the inevitable counter-torque during the recovery phase. Roglič’s TE has improved from approximately 50% in his early WorldTour years to about 68% in peak condition, as reported by his team’s performance staff. Another metric is the “dead spot index,” defined as the percentage of the pedal stroke where torque drops below a certain threshold. By targeting drills that reduce this index—such as single-leg pedaling on a trainer with a high-cadence focus—Roglič has minimized the time spent in unproductive zones.

Training Camps and Altitude

Much of this refinement occurs at altitude training camps in Sierra Nevada or Tenerife. At 2,000 meters above sea level, the reduced oxygen availability forces the body to rely more on efficient muscle recruitment patterns. Roglič’s coaches use these camps to ingrain new movement habits under fatigue. For example, a common drill is to ride a steep (12–15%) gradient at threshold power while focusing exclusively on a smooth, circular stroke, ignoring speed entirely. The heart rate is kept in a narrow bandwidth to ensure the technique is automatic under race-like stress. Over years, these drills have made Roglič’s pedal technique highly robust; even in extremely fatigued states during the third week of a Grand Tour, his stroke remains symmetrical. Data from the 2020 Vuelta a España, which he won, showed that his left-right power balance stayed between 49% and 51% throughout the entire race, a sign of excellent neuromuscular control and bike fit.

Impact on Performance: Case Studies

Roglič’s refined climbing pedal technique has directly translated into race victories. Consider his 2019 Vuelta a España stage win on the Alto de la Covatilla. The climb features ramps above 20% in the final kilometer. Roglič attacked with 1.5 km to go, using a low-cadence, high-torque style that shook off rivals. His pedal stroke during that attack was notably smooth—almost staccato on the steepest parts—showing his ability to apply force without hesitation. Another example: the 2020 Tour de France stage to Col de la Loze, where Roglič paced the ascent with a controlled circular motion, even as the altitude sapped his rivals. Although he lost the yellow jersey later, his climbing efficiency on that day was exceptional, with cadence variations of only 5 rpm over a 40-minute climb. More recently, in the 2023 Giro d’Italia, Roglič won the mountain time trial stage 20 up Monte Lussari, a 7.3 km climb with gradients exceeding 14%. In that performance, his combination of a powerful downstroke and active recovery phase allowed him to average 6.3 watts/kg while maintaining a relatively low heart rate, a direct outcome of years of technique refinement.

Comparison with Contemporaries

To appreciate Roglič’s evolution, it helps to compare him with other elite climbers. Tadej Pogačar uses a more aggressive, high-cadence style with a pronounced pedal bounce (a slight foot lift at the top of the stroke) that allows incredible acceleration but comes at a higher energy cost. Jonas Vingegaard employs a very smooth, almost metronomic circle, similar to Roglič’s but with an even lower cadence preference. Roglič sits between these two: his stroke is smoother than Pogačar’s but more powerful at low cadence than Vingegaard’s. His unique advantage is the ability to change gears and pedal style mid-climb without losing momentum—this flexibility is a product of his ski jumping background, which demanded constant micro-adjustments to position and timing. In head-to-head comparisons on climbs like the Col de la Madeleine, Roglič has matched the pacing of both Pogačar and Vingegaard, suggesting his approach is not only efficient but also adaptable to different race dynamics.

Future Directions: What’s Next for Roglič’s Pedal Technique?

Even at 34, Roglič continues to refine. Recent experiments include adjusting cleat angle on random stages to test for specific gradients, and using variable cadence training that simulates the undulating nature of modern Grand Tour climbs. He has also begun exploring “torque vectoring” during sprints from the saddle, a technique borrowed from track cycling that could give him an edge in reduced group sprints on mountain finishes. While his days of Grand Tour overall wins may be winding down, his impact on cycling technique endures. Young riders now study his pedal stroke data as a benchmark for efficiency. The evolution of Primož Roglič’s climbing pedal technique is a testament to the power of deliberate practice, biomechanical science, and relentless self-optimization—a model for any athlete seeking to turn a weakness into a weapon.

Conclusion: The Long, Steady Ascent to Technical Mastery

Primož Roglič’s journey from an upright, power-mashed climbing style to a fluid, data-informed circular pedal stroke illustrates the depth of modern cycling performance. It was not a single revolutionary change but a series of small, evidence-based adjustments over a decade: a change in cleat position, a subtle shift in saddle height, thousands of focus-intensive trainer sessions, and real-time biomechanical feedback. Each modification built on the previous, creating a climbing engine that works in harmony with his unique physiology. His ability to apply maximum torque with minimal wasted movement has made him one of the most formidable climbers of his generation, capable of winning multiple Grand Tours and standing atop the world’s toughest mountains. As cycling continues to evolve, Roglič’s methodical approach to technique refinement will serve as a blueprint for future champions—a reminder that even at the highest level, there is always room to climb higher.
