Whats New — Lapierre XR & XRM

The final replace to the Lapierre XR line was in 2017, and loads has modified within the cross-country world since then. Lapierre should have been watching carefully on the traits because the up to date XR and XRM seem able to tackle the large canine of cross nation.

Lapierre XRM

The XR is the lighter, extra race-focused of the 2 new body choices, with 100mm of entrance and rear journey, accessible in an ordinary carbon, and an optimized carbon layup for added weight discount. The XRM bumps the journey as much as 120mm entrance and 110mm rear, not centered on weight discount however extra so on versatility.

Trimming the fats

Lapierre made it no secret that weight discount was a important design focus for the XR line. Whereas pushing for lighter frames, Lapierre refined its carbon manufacturing course of. Shifting from customary pre-impregnated unidirectional carbon fiber to a brand new carbon building technique, it calls UD SLI (Unidirectional Superlight Innovation). Using unidirectional Torayca carbon fibers, praised for distinctive lightness, power, and stiffness. Lapierre can preserve the power of the body excessive and the burden comparatively low, for the cross nation specialists.

Lapierre developed a brand new polypropylene inflexible mandrel to optimize these new UD SLI fibers. This mandrel provides better precision within the layup course of, and higher compression of the fibers within the mould. The objective was to put off extra resin whereas sustaining a body that may put up with the pains of mountain bike using.

Wouldn’t a lighter, thinner body crack simpler? Lapierre says the brand new layup course of is stronger than the earlier and is optimized to maintain power in high-impact areas. Lapierre states there are over 300 sheets of carbon fiber per body, and due to the power, it has been potential to scale back the thickness of the tubes wherever potential.

Lapierre shaved loads of weight from simplifying the rear triangle, eradicating pivots, and scaling down the seat stays, leading to a claimed 90g saving. Due to the brand new UD SLI layup, the chainstays are good and stiff, considerably cumbersome however have thinner partitions.

Lapierre claims a naked body (excluding the shock, bearings, and bolt {hardware}) of the XR / XRM Workforce is available in at 1,772g. The usual model of the naked body is available in at 1,970g.

Lapierre XR and XRM up to date suspension

One other deal with the up to date XR and XRM was suspension kinematics. Lapierre modified the rear shock placement and, with the brand new pivotless and thinned-out rear triangle, developed a novel suspension they dubbed Optimised Sensitivity System.

Lapierre suspension engineers moved the shock beneath the highest tube to compress extra immediately. Additionally they positioned the pivot above the underside bracket and barely greater than the earlier years to counteract pedal kickback when the suspension compresses. The change lowered stress on the seat tube, and a molded carbon “protect” helps defend the stanchions from bits of path particles.

Lapierre says the kinematics of the brand new flex seat stays permits a relentless sag as they preserve a impartial place when the sag is ready at 26 p.c, unbiased of the rider’s weight.

New Geomtery Lapierre XR and XRM

The Lapierre XR and XRM be a part of different mountain bike producers, shifting in direction of an extended attain, steeper seat tube angle, and slacker head angle. The XR includes a fairly relaxed (for XC) 67-degree head tube angle, and the XRM will get a full diploma drop to 66-degrees. The seat tube angle is steepened by one diploma from the outgoing mannequin to 75.5 levels on the XR however stays 74.5 levels on the XRM.

The up to date frames characteristic inner cable routing, guided by a Kevlar-lined mould by way of the entrance triangle, exiting close to the central pivot and coming into once more on the rear triangle. Each fashions used a PF 92 press-fit backside bracket.
