Lapierre Pulsium 500 Road BikeRough roads and the unique challenges of the spring classics require a very special approach and the Pulsium 500 endurance race bike is perfect for these, as it has a serious trick up its sleeve. Enhanced ComfortThe key to mastering the cobbles is Shock Absorption Technology. An elastomer connection between the seat and top tubes absorb and dampen impacts, stopping them propagating through the rest of the bike and upsetting the handling. This gives far greater comfort on rough surfaces, which lets you ride longer and harder without fatigue Features: Frame: Pulsium Carbon Fibre Forks: Lapierre Pulsium Carbon Fibre with Carbon steerer Headset: FSA 1 1/8″ – 1 1/4″ FSA Orbit C-33 44E + 15mm top cover Bottom Bracket: Shimano BB71 pressfit Crankset: Shimano 105 FC5800 50Tx34T Stem: Lapierre with LP cap 7° Rise, 31 8mm diameter Handlebar: Lapierre HB-CR12 Front Derailleur: Shimano 105 FD5800 Rear Derailleur: Shimano 105 RD5800GSL 11-speed Brakes: Shimano 105 BR5800 Shifters: Shimano 105 ST5800 2×11-speed Seatpost: Lapierre SP-3D1, 27 2mm diameter, 350mm length Saddle: Aliante R5 MG Wheels: Shimano RS010 Cassette: Shimano 105 CS5800 – 11-speed 11-32T Tyres: Continental Ultra Sport 2 700x25cEasy AssemblyWhen you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping.
