Lapierre Pulsium 4.0 – Carbon Endurance Road Bike

Comfort-oriented carbon endurance road bike designed for long climbs, smooth descents and all-day riding performance.

We highly recommend this bike for cyclists who want comfortable gearing for Mont Ventoux and ride at least 1,500–2,000 km per year.

Why rent Lapierre Pulsium 4.0?

The Pulsium 4.0 is built around Lapierre’s high-modulus carbon frame, offering the perfect balance between stiffness for climbing and compliance for long-distance comfort.

Its endurance geometry provides a slightly higher front end, reducing pressure on the back and shoulders — ideal for long ascents like Mont Ventoux.

The Shimano GRX 2x10 drivetrain offers wide and forgiving gearing (46/30 with 11-36T cassette), making it easier to maintain cadence on steep gradients. This setup is particularly suitable for riders who prefer comfort and smooth climbing rather than aggressive racing positions.

Hydraulic disc brakes ensure reliable stopping power on fast descents, while 32mm tyres increase comfort and stability on imperfect road surfaces.

The Pulsium 4.0 is the ideal carbon choice for riders who want performance without going full race-spec.
