Pulsium

Algupära

Võidusõiduks valmis vastupidav maanteeratas. Ajalooliselt määratletud SAT (Shock Absorption Technology) elastomeeriga istmetugedes; 4. põlvkond loobub elastomeerist ja kasutab uuelt Xelius DRS-lt laenatud '3D Tubular' vastavusdisaini. Kergem, aerodünaamilisem ja agressiivsem kui eelmine Pulsium — Lapierre positsioneerib ratta lähemale kiirele universaalrattale.

Tehnilised andmed

Raam: UD SL standard-modulus carbon fibre; 992 g raw frame (size M), ~100 g lighter than the 3rd generation
Kahvel: Full-carbon Pulsium fork, ~380 g (uncut steerer); head tube and fork shaping inherited from the Xelius DRS, fully internal cable routing
Jõuülekanne: Shimano 2x12: 105 mechanical (5.0), 105 Di2 (6.0), Ultegra Di2 (7.0/8.0); SRAM Rival AXS 2x on 6.0 AXS — mostly electronic across the range
Pidurid: Hydraulic disc, flat-mount, with 12 mm thru-axles front and rear
Rattad: DT Swiss alloy on most builds; flagship Pulsium 8.0 gets DT Swiss ERC 1600 Spline carbon, 45 mm deep, 22 mm internal width
Rehvid: Continental or Schwalbe 32 mm fitted stock; frame clears up to 38 mm (with mudguards)
Vedrustus: Rigid; compliance from 3D Tubular seatstays + 27.2 mm round seatpost. Claimed ~5.5% more vibration damping than the previous SAT-elastomer generation
Rooliplokk: Alloy Lapierre stem, -10°, with semi-internal cable routing; alloy bar with 10° flare; 27.2 mm round seatpost with hidden wedge clamp; out-front GPS mount included
Sadul: Lapierre/OEM road saddle on 27.2 mm round seatpost with hidden wedge clamp (varies by build level)
Geomeetria: Race-tuned endurance: stack lowered 9-19 mm, head tube shortened 20 mm, seat tube 0.5° steeper, slightly longer reach on small sizes; 415 mm chainstays; e.g. size L stack 579 mm / head tube 175 mm. Six sizes XS-XXL.
Kaal: ~8.3 kg (8.0, Ultegra Di2 + DT Swiss carbon) to ~8.8 kg (6.0); frame 992 g + fork 380 g (size M)

Verdikt

+Tugevused

Lighter and more aero than the previous generation: ~100 g frame saving (992 g M) and a claimed 5% aero gain / 6.1 W at 50 km/h.
Generous 38 mm tire clearance with mudguard mounts — versatile enough to stray onto light gravel and all-road.
3D Tubular seatstays deliver compliance (claimed ~5.5% more damping) without the maintenance/age concerns of the old elastomer block.
Sportier, lower geometry plus integrated GPS mount, top-tube bag and fender mounts — built for fast endurance and ultra-distance.
Mostly electronic-shifting builds (Shimano Di2 / SRAM AXS) at competitive prices for a carbon endurance bike (from ~€2,600).

−Nõrkused

Stock 32 mm tires don't use the available 38 mm clearance, leaving comfort and grip on the table out of the box.
Lower stack and more aggressive fit may not suit riders who chose the Pulsium for a relaxed, upright endurance position.
No internal frame storage despite the endurance/ultra-distance positioning.
992 g frame is only modest by current endurance-carbon standards — it is not a featherweight climber.
Dropping the signature SAT elastomer is a leap of faith: comfort now rests on tube flex rather than the proven damper, and long-term real-world ride feel is not yet broadly reviewed.

Kellele sobib

Long-distance road rider, sportive/gran fondo, gravel-curious commuter who wants 32–38mm rubber comfort without giving up race responsiveness.
