Lapierre has over­hauled the Pulsium model for 2018, with the 900 on test be­ing the high­est model in the range. The Pulsium is a bike de­signed for the rough­est roads and for big dis­tances, and is used by the Lapierre-spon­sored World Tour team FDJ to tackle events like Paris-roubaix with its in­fa­mous cob­bled farm tracks. Com­fort is with­out doubt the main goal of the bike and one that it suc­ceeds in, with the Shock Ab­sorp­tion Tech­nol­ogy (SAT) giv­ing a very smooth ride at both front and rear. A no­table im­prove­ment in the new ver­sion com­pared to pre­vi­ous mod­els is in its lat­eral stiff­ness and re­sponse to pedal in­puts, with no no­tice­able flex in the frame un­der even the big­gest ef­forts. The spec­i­fi­ca­tion is se­ri­ously im­pres­sive, in­clud­ing the com­plete new Dura-ace 9150 Di2 groupset, with its Syn­chro Shift op­tion and ex­tra pro­gram­mable but­tons that can be used for some­thing like a com­pat­i­ble GPS com­puter. Gear-shift­ing qual­ity is ex­cep­tional, as you’d ex­pect. Rounded off with a com­fort­able car­bon han­dle­bar and stem from Zipp and a light­weight and com­fort­able car­bon-railed Fizik sad­dle. One of the ben­e­fits of all th­ese high-end com­po­nents is that the Pulsium 900 is very light. Com­bined with the re­spon­sive frame, this helps it to climb su­perbly, with the long­est and steep­est alpine climbs be­ing no is­sue. Help­ing keep the weight low are the high-end Mavic Kys­rium Pro Car­bon SL wheels, which are a claimed 1,400g. The low weight is eas­ily no­tice­able in any sprints or steep climb and the brak­ing per­for­mance is also im­pres­sive, es­pe­cially for car­bon rims, giv­ing ex­cel­lent feel, mod­u­la­tion and not a hint of brake fade on even the long­est alpine des­cent. The wheels are rea­son­ably stiff, but big­ger or very pow­er­ful rid­ers might no­tice a hint of flex un­der big­ger power ef­forts. Han­dling and cor­ner­ing con­fi­dence is a real strong point, helped by the ex­cel­lent brakes and ride com­fort, but also the geometry and rider po­si­tion, which is a per­fect mix of agility with a feel­ing of be­ing safe and ca­pa­ble.

The high spec of the Pulsium 900 helps it achieve very low weight
