Since its launch in 2014 on the cobblestones of Roubaix or Flanders, the Pulsium has built a reputation and demonstrated its effectiveness in terms of comfort whatever the state of the
route. In 2021 the model had taken a less sporty path, assumed by a more comfortable geometry. It was time to put the endurance bike back in its initial element: more performance and surpassing oneself.

Even more vertically comfortable, lighter, more aerodynamic and more racing-oriented than the last generation, the latest Pulsium symbolises a new approach from cyclosport to ultra-distance events.
From SAT to 3D Tubular: more than 10 years of evolution and visual signature
routes asphalted and paved with routes degraded, Pulsium has always had this ability to erase imperfections.
Further improving the feeling of comfort while simplifying the concept and strengthening the identity of the bike, this is what led Lapierre to prefer the 3D Tubular Endurance concept to the SAT system with its elastomer.
Lighter, more refined, the 3D Tubular concept has proven itself at the highest level, both in World Tour races and in Cross-Country MTB.
Thanks to 3D Tubular, construction is simplified while visually lightening the lines of the frame.
3D Tubular, the proven solution
On average 5 to 7% more efficient at the seat tube and saddle, the 3D Tubular special endurance does even better than the SAT system.
The specific design of the 3D Tubular, with its break before the junction with the upper tube, improves the dispersion qualities of low frequency vibrations (50 Hz)
Even more “flexible” vertically, thanks to the combination of Flexstays seat stays, the new 3D Tubular and the 27,2 mm round seat tube, the Pulsium filters low frequencies as much as possible whatever the speed.
The cyclist can therefore concentrate on his effort, pedal calmly and maintain muscle freshness to ride for longer.
Take control: from cyclosport to ultra
Making the Pulsium sportier again, without being extreme. This is the challenge that Lapierre wanted to take up by making concrete changes to the geometry.
To do this, the brand started from scratch and thought of those who wanted to go the distance, even beyond their expectations.
The vision of cyclosport in the broad sense of the term has been revised. With a sportier geometry but accessible to any amateur cyclist, the Pulsium is placed in the sport/performance category.
Also, a 6th size appears, XXL, for larger cyclists.
Take Control: Small Changes That Make a Big Difference
The frame is slightly more sloping for handling, with a slightly straighter seat tube to put the rider back on the front, a slightly more aggressive stack/reach ratio, and of course a lower head tube to improve the rider's aero position and have a more dynamic bike to ride. The combination of all these modifications gives the Pulsium a more assertive but not exclusive character.
The changes in five points
1. 2 cm lower head tube (1,5 cm for size XS)
2. Saddle angle straightened by 0,5°
3. Scalable stack (9 to 19 mm) depending on the sizes
4. 4mm longer reach for sizes XS to M
5. 415mm bases, compatible with 38mm tires
A new stack/reach ratio
The geometry of the new Pulsium is a bit more aggressive than the previous generation. Although more performance-oriented, the new Pulsium remains far from the performance geometry of the Xelius DRS.
It is therefore more suited to performance while remaining close to a relatively market neutral stack/reach ratio.
Why a more aero Pulsium?
Taking part in a cyclosportive, an ultra distance, means challenging yourself, pushing your body to its limits.
So why not have a bike that also lives up to the expectations of every cyclist.
A bike that is better, faster, without falling into the extreme. It is also a vision of cyclosport and ultra distance. Save precious seconds so that you arrive earlier, fresher.
Aero isn't always everything, but it's a performance factor that engineers couldn't neglect or put aside.
Certified aero gains: lines in the age of wind
The transposition of NACA and KAMMTAIL tube sections from the Xelius DRS to the Pulsium at the fork crown and tapered head tube level made it possible to maximize air penetration of the front of the bike. Result, a few watts saved and seconds gained without any effort. Performance also begins with these marginal gains.
– 5%* more aero than Pulsium/Pulsium SAT
– 6,1 watts more efficient* at 50 km/h, i.e. 4 seconds gained every 10 km
– 2,1 watts more efficient* at 35 km/h, i.e. 5 seconds gained every 10 km

Carbon UD SL: definitely the best quality/price/performance ratio
In Lapierre's mind, it seemed obvious that the new Pulsium had to be more dynamic, lighter and therefore more efficient than its predecessor, while remaining accessible to the greatest number of people.
It is quite logical that the engineers opted for a UD SL carbon level: to date, for Lapierre, this is the best carbon level for non-professionals or experts.
Its construction in unidirectional carbon fibers of Standard Modulus quality is optimized. The plies are scratched and placed under vacuum around a latex mandrel in order to ensure a high level of compression between the different plies and to expel a maximum of resin during its cooking phase to lighten the final construction.
Efficiency to roll faster – new Lay-up
The frame of the new Pulsium is also optimized for ultra distance and equipped with several fixing inserts such as on the top tube or discreetly placed on the fork and seat stays to accommodate a front and rear mudguard, always compatible with 38 mm tires.
Despite this, and thanks to its UD SL construction, the new Pulsium frame remains under the kilo threshold, with a frame weighing 992 g*, or 100 g less than the old model.
The fork is also relatively light in its category at only 380 g**.

Transmission
– A varied and complete offer
Seven models make up the Pulsium 2025 range, with two color choices for the 6.0 and 7.0 models.
And six of the seven models are equipped with electronic groups with wireless transmission, Shimano Di2 or SRAM AXS.
– Electronic groups in number
Like our performance range, the Pulsium family therefore rhymes with modernity thanks to the electronic transmission. Reliability and speed precision are an asset for long rides. The speed, precision and customization of gear changes via dedicated applications allow you to concentrate on the effort.
