The alloy version of the Specialized Crux is back, and its lighter than ever! The all-new Specialized Crux DSW mimics its carbon brethren and weighs only 1399 grams for a frameset. However, this Crux isnt the same World Champion Bunny Hopper cyclocross steed that Zdenk tybar raced. Its a gravel bike, and its the lightest alloy gravel bike ever made.(Photo/Specialized)Specialized Crux DSWIf youre new or returning to the Specialized Crux, the latest iteration pivoted towards the gravel side of life, moving away from the cyclocross race machine of the past. The new Crux is still a cyclocross-able machine, but the geometry and slopping toptube say gravel. The newest Crux version was also deemed the lightest gravel bike ever, and now its alloy counterpart shares the crown.(Photo/Jordan Villella)DAluisio Smartweld ConstructionHow did it get so light? The design team at Specialized uses the same DAluisio Smartweld (DSW) youll find on the Allez sprint. Its an engineering process that uses hydroforming to match tube-to-tube joints for better, stronger welds. This type of construction produces a lighter frame, and it is claimed to be twice as durable as a traditional alloy frame.(Photo/Specialized)Connecting the PiecesThe DSW frames are assembled using a single-piece downtube and bottom bracket, identical to the construction of the Allez Sprint. This one-piece downtube and bottom bracket help stiffen the bike and pedaling response. (Photo/Specialized)The seat tube and chainstays are then mated to the hydroformed one-piece downtube and bottom bracket using the Specialized DAluisio Smartweld welding process.(Photo/Specialized)Specialized says the DAluisio smart weld process is refined, eliminating the need to overbuild tubes and welds. The yield is a 1399g alloy frame alone, but it also brings better ride quality and responsiveness.(Photo/Specialized)Frame Details The Crux DSW keeps its weight down with help from a full carbon Fact12r Crux fork, like the carbon Crux versions. It has a threaded bottom bracket and upgrades to a SRAM UDH rear derailleur hanger (unlike the current carbon Crux).(Photo/Specialized)The frame boasts mechanical and electronic shifting compatibility, with zero headtube routing.(Photo/Specialized)The tube shapes are slightly round for seat stays, and the top tube is slightly triangular. This might scare away some soft-shouldered cyclocrossers, but dont fear; the tube tappers are flat near the seat tube junction. (Photo/Jordan Villella)Specialized claims a complete Crux DSW tips the scales at 20lbs (9.37g) in a 56cm in the lightest colorway, and we found that to be 100% true on our scales. (Photo/Specialized)What type of riding is it for?The Crux DSW has the exact geometry and tire clearance as its carbon counterpartthats up to 47mm on 700c wheels and up to 2.1 on a 650b wheel. Its basically the carbon Crux, only aluminum. Its safe to say the new Crux DSW is a gravel bike that can take a beating.(Photo/Jordan Villella)The jury is out on how stiff and compliant that ride will be. Judging from my time on the Crux in both cyclocross and gravel, my hopes are high. (Photo/Specialized)Ride Tuned For On and Off-RoadAlloy gets a bad rap for being harsh off-road. But anyone who rides a well-crafted alloy frame will tell you thats not 100% true. Its all about tube shapes and geometry. (Photo/Jordan Villella)For the Crux DAluisio Smartweld, the slightly longer reach delivers better weight distribution, and the full carbon fork eats up trail chatter, same a mix of round tubes.(Photo/Jordan Villella)Like the carbon model, it should offer a stable ride with an in the middle for gravel and cyclocross 72mm of bottom-bracket drop.(Photo/Jordan Villella)Specialized Crux DSW ModelsThe Specialized Crux DSW is available in a complete or frame-only model. The frames arrive in super cool, playful colors like the alloy Crux of the past. The complete bike offers a competitively built gravel machine that is a solid option when pitted against the Crux carbon.(Photo/Jordan Villella)The Crux DSW Comp arrives with an SRAM 12-speed Apex setup, an 11-44T cassette, and a 40T front chain ring. As built, the bike weighs 20 lbs, but most is in the wheels, seatpost, and alloy bars.The saddle is a base-level Specialized Power and a great do-it-all saddle.(Photo/Jordan Villella)Overall, the spec is solid. The wheels, though slightly heavy for racing, are an excellent spec for gravel and exploration on the bike.(Photo/Jordan Villella)The rims are 25mm internal and, paired with the Specialized Pathfinder Pro tires, offer an excellent footprint for traction and speed.Specialized Crux DSW SpecsFrame: Specialized E5 Premium Aluminum Disc frame DAluisio Smartweld Technology, hydroformed aluminum tubing, tapered head tube, threaded BBFork: FACT Carbon, 12x100mm thru-axle, flat-mount discHandlebars: Specialized Adventure Gear, 118.9mm drop x 70mm reach x 12 flareStem: Specialized, 3D-forged alloy, 4-bolt, 7-degree riseFront brake: SRAM APEX, Hydraulic DiscRear brake: SRAM APEX, Hydraulic DiscShift lever: SRAM APEX, 12spRear derailleur: SRAM APEX XPLR, MechanicalCassette: SRAM PG 1231, XPLR, 11-44Crankset: SRAM APEX XPLR, 40tChainring: 40tBottom bracket: SRAM DUB BSA 68 WideChain: SRAM APEX 12SWheels: DT G540, Centerlock Disc, Tubeless Ready, 25mm internal width Tires: Pathfinder Pro 2BR, 70038Saddle: Body Geometry Power Sport, steel railsSeatpost: Alloy, 2-bolt Clamp, 12mm offset, 27.2mm, anti-corrosion hardwareTotal Weight: 9.37kg (20 lb, 10.5 oz) Size: 56cmSpecialized Crux DSW PricingCrux DSW Comp: $2,600, 2,700, 2,300, AUD 4,000DSW Frame: $1,700, 1,650, 1,500, AUD 2,500AvailabilityThe new Specialized Crux DSW is shipping nowto retailers and customers.Look For a ReviewWe just received our review ride for the Specialized Crux DSW.
