<\/a>Lapierre XR 729 ei.<\/span><\/p>\nFrame geometry is heavily reworked around shorter, stiffer stems, with a reach that\u2019s a full 20mm longer. The head angle is a degree slacker at 69 degrees, and the combined result is a front axle that\u2019s further forward for improved stability on descents and less lift on climbs. The seat tube has been steepened significantly to 74.5 degrees to keep weight over the front and boost steering accuracy, while the chainstays are 5mm shorter to keep manoeuvrability high.<\/p>\n
Suspension performance is also improved, with full-carbon pivots representing a lightweight adaptation of our OST+ system. OST+ is our highly-evolved virtual pivot point design that has itself seen further development this year to adapt to race usage.<\/p>\n Maintenance access across the frame is deliberately easy, plus the XR benefits from Trap Door Technology. TDT brings integrated Di2 fitting, and tucks batteries inside the downtube away from the elements \u2013 while allowing instant access for charging. TDT is sited very low, right alongside the bottom bracket, to centralise and lower the mass, and minimise its effects on handling.<\/p>\n The full-carbon frame is also compatible with internally-routed dropper posts, and for 2017 it\u2019s stiffer for its weight.<\/p>\n Wheels are now stiffer and stronger too thanks to Boost axle spacing (148mm\/110mm), while the shocks also gain lateral stiffness thanks to the greater bushing overlap afforded by RockShox\u2019s new metric-sized Deluxe RL. The shock\u2019s redesigned body also benefits from longer wiper seals for extended service times, reduced friction for more supple movement and space for significant internal upgrades. They\u2019re built to ride high in their travel to maintain controlled, predictable geometry and excellent pedalling manners \u2013 ideal for the XR.<\/p>\n Still super-lightweight with its unidirectional carbon frame and rocker, the XR is now faster everywhere on the hill.<\/p>\n The range-topping XR 929 makes the utmost of all this new technology with more of the latest developments \u2013 specifically, SRAM\u2019s new 12-speed Eagle drivetrain, RockShox\u2019s super-stiff RS-1 inverted fork, and our renowned e:i electronic rear suspension.<\/p>\n There are four models in four sizes (S-XL), with the XR 929 Ultimate representing the absolute pinnacle of current XC\/marathon race development.<\/p>\n XR 929<\/strong><\/p>\n XR 729 \/ 729 e:i<\/strong><\/p>\n XR 629<\/strong><\/p>\n XR 529<\/strong><\/p>\n As successful and popular as the Xelius is \u2013 it\u2019s won l\u2019Alpe d\u2019Huez on the Tour de France and Race Bike of the Year in the specialist press \u2013 we\u2019re not ones to rest on our laurels. Hence not just this new disc-equipped model, but a ground-up redesign of the frame to make the very best of new braking technology.<\/p>\n The full-carbon frame and fork are disc-specific, and use Shimano\u2019s popular Flat Mount standard (since adopted by companies including SRAM) for easy compatibility. Both ends hold 12mm hollow axles, which seriously boost rigidity across the fork tips and dropouts. These help resist the twisting forces of powerful discs, and increase wheel security at the same time.<\/p>\n Front axle spacing is 100mm, while the rear is up from 135mm to 142mm for greater triangulation and stiffness. The chainstays are 10mm longer at 415mm to accommodate the wider wheel.<\/p>\n Shimano hydraulic calipers feature Icetech finned pads for extra cooling, and bite down on lightweight 140mm discs. Being further from road spray and the oil and diesel it contains, disc brakes are far more consistent and powerful in the wet. Also, going disc-specific allows weight to be removed from the rims, and the centralisation of mass reduces rotational weight for gains in acceleration and manoeuvrability at speed.<\/p>\n Greater braking power means greater heat, so the carbon fibre is special. For the Xelius SL Disc we use a High TG resin that protects against temperatures up to 190C, whereas non-disc frames only require a TG point of 140C. The TG point, also known as the glass transition temperature, is where a polymer turns from a solid to liquid. It\u2019s not quite the same as the melting point, but it\u2019s still absolutely vital to understand when you\u2019re designing a frame.<\/p>\n The unidirectional carbon fibre frame retains the successful Superlight layup, and features internal routing for slippery-clean aero lines. 3D Tubular technology means the seatstays connect directly to the toptube for reduced weight and mechanical stress \u2013 plus increased comfort \u2013 while Power Box sees the tapered headtube, downtube, bottom bracket shell and chainstays forming one extremely stiff structure. New sandwich-type dropouts generate higher rigidity for crisper acceleration and shifting.<\/p>\n The result?<\/strong> An extremely light frame with world-level pedalling manners that\u2019s all-day comfortable, loves descents as much as climbs, and stops on a dime. Or perhaps more accurately, a Euro.<\/p>\n The six sizes range from XS to XXL, while crank length, stem length and handlebar dimensions are tailored to each one. All sizes and models feature 2×11 Mid Compact drivetrains, with 52x36T rings and 11-28T cassettes.<\/p>\n The three models range from the accessible 500 to the exceptionally-specced Ultimate. Model highlights include:<\/p>\n The Sensium has been redesigned for 2017, with a lightweight new frame that makes long-distance riding even sweeter. The layup and construction of the unidirectional carbon is finely tuned across three key zones \u2013 the result is a bike that gets all your power to the ground, yet doesn\u2019t beat you up in the process.<\/p>\n We\u2019ve focused on a stiff and responsive front end for accurate handling, compliant upper tubing for fatigue-reducing comfort, and a very stiff, Power Box-enhanced lower spine for instant and highly efficient power transfer.<\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a>Lapierre XR 929 Ultimate.<\/span><\/p>\n<\/a>Lapierre XR 629 ei.<\/span><\/p>\n\n
