Lapierre unveils its new Pulsium, its revisited endurance model

Since its launch in 2014 on the cobblestones of Roubaix and Flanders, the Pulsium has built a reputation and demonstrated its effectiveness in terms of comfort, regardless of road conditions. In 2021, the model took a less sporty direction, adopting a more comfort-oriented geometry. It was time to put the endurance bike back in its initial element: more performance and self-transcendence.

Even more vertically comfortable, lighter, more aero, and more race-oriented than the previous generation, the latest Pulsium symbolizes a new approach from sportives to ultra-distance events.

From SAT to 3D Tubular: over 10 years of evolution and visual signature

From paved and cobbled roads to degraded roads, the Pulsium has always had the ability to smooth out imperfections.
Further improving the feeling of comfort while simplifying the concept and strengthening the bike’s identity is what led Lapierre to prefer the 3D Tubular Endurance concept over the SAT system with its elastomer.
Lighter and more streamlined, the 3D Tubular concept has proven itself at the highest level, both in World Tour races and Cross-Country mountain biking.
Thanks to 3D Tubular, construction is simplified while visually lightening the frame’s lines.

3D Tubular, the proven solution

On average 5 to 7% more effective at the seat tube and saddle level, the special endurance 3D Tubular performs even better than the SAT system.
The specific design of the 3D Tubular, with its break before the junction with the top tube, improves the dispersion qualities of low-frequency vibrations (50 Hz).
Even more vertically “flexible,” thanks to the combination of Flexstays seatstays, the new 3D Tubular, and the 27.2 mm round seat tube, the Pulsium filters low frequencies as much as possible, regardless of speed.
The cyclist can thus concentrate on their effort, pedal calmly, and maintain muscle freshness to ride longer.

Take control: from sportive to ultra

Making the Pulsium sportier again, without being extreme. This is the challenge Lapierre wanted to take on by making concrete modifications to the geometry.
For this, the brand started from a blank slate and thought of those who wanted to go the distance, even beyond their expectations.

The vision of sportives in the broadest sense of the term has been revised. With a sportier but accessible geometry for any amateur cyclist, the Pulsium is repositioned in the sport/performance category.
Also, a 6th size appears, XXL, for taller cyclists.

Take control: small changes that make a big difference

The frame is slightly more sloping for maneuverability, with a slightly steeper seat tube to reposition the cyclist forward, a slightly more aggressive stack/reach ratio, and of course a lower head tube to improve the cyclist’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. Head tube 2 cm lower (1.5 cm for size XS)
2. Seat angle steepened by 0.5°
3. Evolving stack (9 to 19 mm) depending on size
4. Reach 4 mm longer for sizes XS to M
5. 415 mm chainstays, compatible with 38 mm tires

A new stack/reach ratio
The geometry of the new Pulsium is a little more aggressive than the previous generation. Although more performance-oriented, the new Pulsium remains far from the Xelius DRS’s performance geometry.
It is therefore more adapted to performance while remaining close to a relatively neutral stack/reach ratio on the market.

Why a more aero Pulsium?

Taking on a sportive or an ultra-distance event means challenging yourself, pushing your body to its limits.
So why not have a bike that also meets every cyclist’s expectations?
A bike that is better, faster, without being extreme. This is also a vision of sportives and ultra-distance. Gaining precious seconds so you arrive earlier, fresher.
Aero doesn’t always do everything, but it’s a performance factor that engineers couldn’t neglect or set 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 allowed for maximizing air penetration at the front of the bike. The result is a few watts saved and seconds gained without any effort. Performance also begins with these marginal gains.
– 5%* more aero than the Pulsium/Pulsium SAT
– 6.1 watts more efficient* at 50 km/h, or 4 seconds gained every 10 km
– 2.1 watts more efficient* at 35 km/h, or 5 seconds gained every 10 km

UD SL Carbon: decidedly the best value for money/performance

In Lapierre’s mind, it seemed obvious that the new Pulsium had to be more dynamic, lighter, and therefore more performant than its predecessor, while remaining accessible to the greatest number.
It was therefore logical that the engineers opted for a UD SL carbon level: for Lapierre, this is currently the best carbon level for non-professionals or experts.
Its construction with optimized Standard Modulus unidirectional carbon fibers. The plies are scored and vacuum-placed around a latex mandrel to ensure a high level of compression between the different plies and to expel a maximum of resin during its curing phase to lighten the final construction.

Efficiency for faster riding – new Lay-up
The frame of the new Pulsium is also optimized for ultra-distance and equipped with several mounting inserts, such as on the top tube or discreetly placed on the fork and seatstays to accommodate front and rear mudguards, still compatible with 38 mm tires.
Despite this, and thanks to its UD SL construction, the new Pulsium frame remains below the one-kilo threshold, with a frame at 992 g*, which is 100 g less than the old model.
The fork is also relatively light in its category at only 380 g.

Drivetrain
– A varied and complete offer
Seven models make up the 2025 Pulsium range, with two color choices for the 6.0 and 7.0 models.
And six of the seven models are equipped with wireless electronic groupsets, Shimano Di2 or SRAM AXS.

– Numerous electronic groupsets
Like our performance range, the Pulsium family is synonymous with modernity thanks to electronic shifting. The reliability and shifting precision are an asset for long rides. The speed, precision, and customization of gear changes via dedicated applications allow you to concentrate on your effort.
