Lapierre’s endurance road Pulsium started out as a Classics bike designed for Roubaix & Flanders cobbles, before evolving for more comfort. But in 2025 the 4th generation carbon Lapierre Pulsium is ready to get back to racing as a lighter and more aerodynamic road bike with race-tuned geometry. While at the same time, still managing to deliver even better rider comfort to take on the longest days in the saddle.
2025 Lapierre Pulsium carbon endurance all-road bike
Lapierre says they can deliver both comfort AND performance, perfect for riders taking on their first gran fondo and for racers tackling longest ultra-distance events. Oh, and 100g lighter than before, while maintaining affordability!
It’s been more than a decade since the first Pulsium debuted the elastomer-damped SAT suspension concept on the road. We caught up with FDJ on their further refined 2nd gen bikes at Paris Roubaix in 2017, before Lapierre dialed back the race-readiness with a more amateur-focused 3rd generation.
But now Lapierre takes the Pulsium back to its racing roots.
What’s new?
100g lighter. 5% more aero. 5.5% more vibration damping.
Lapierre now updates their endurance bike with the lighter 3D Tubular design from their race bikes, bypassing seatstays around the seattube to better isolate the rider from low-frequency (50Hz) vibration vs. the heavier SAT elastomer solution.
Plus, the combination of flexstays, 3D Tubular construction, and a round 27.2mm seatpost create an all-around more supple feel at the saddle, at both low & high riding speeds.
More aero, too!
Of course, aerodynamic optimization is everywhere these days. And endurance road means longer times out, riding solo in the wind, even if at lower than pro racing speeds. So, Lapierre tweaked the new Pulsium to make it faster where they could.
“Aero isn’t always everything, but it’s a performance factor that our engineers couldn’t neglect or set aside.”
The 2025 Pulsium inherits aero headtube and fork leg shaping from the recent Xelius DRS to smooth airflow over the front of the new endurance road bike. Lapierre says it makes this new bike “5% more aero” vs. the 2021 Pulsium. And that means a 6.1W savings at 50kph, or in real terms 4 seconds saved every 10km. Or still 2.1W savings at a more realistic 35kph speed, which actually means even more – 5 seconds saved every 10km.
Those marginal gains add up when you are out on the road longer.
All-new race-ready geometry
With more of a focus on speed, Lapierre also fine-tuned endurance geometry for a “sportier” feel, while keeping it “accessible to all amateur cyclists”.
The biggest shift was to decrease Stack between 9-19mm for riders looking for a lower, more aero fit on the bike. Plus, slightly longer Reach on the smaller sizes to limit toe overlap with big tires and improve stability. So, Stack:Reach ratios are a bit more aggressive but still in a neutral range. And nowhere close to their full-on Xelius DRS, SL3 & Aircode race bike family.
The new Pulsium also flattens its toptubes a bit and features a 1/2° steeper seattube. Plus, Lapierre also adds a sixth new XXL size for taller riders, too.
