Bikes

Four decades after the first Specialized Allez hit the road, the new Allez is the best yet. Lightest in its class,† it delivers more confidence, versatility, and performance than ever before – to more riders than ever before. Whether you’re looking for premium alloy, want a bike for weekend rides and fast commutes, or if you’re just beginning your road journey, performance road starts with Allez. LIGHTEST IN CLASS: Starting with premium butted and double-butted E5 alloy, the Allez frame tips the scales at just 1,375†† grams for a quick and nimble feel on the road. Plus, the full carbon fork reduces weight even more (no hidden alloy steer tube here) while helping smooth out your ride. And with modern, thoughtful build choices, it’s no surprise the Allez is also the lightest in its class. INCREDIBLE CONFIDENCE: This premium E5 alloy frame is light, fast, durable, and, did we mention, gorgeous? The excellent stiffness-to-weight ratio coupled with the unmatched stopping power of all-weather dual-piston disc brakes delivers ultimate confidence at any speed. Plus, we’ve used the legendary Roubaix bike's endurance geometry to deliver unrivaled comfort for long miles and stable handling while ensuring the Allez can still dissect a winding road like a pure race bike. VERSATILITY AND PERFORMANCE: Just as capable of getting you to work or class, as it is checking off your local KOM or weekend group ride, racks and fender mounts ensure the Allez is versatile enough for whatever road you take it on. With tire clearance up to a beefy 35 mm (32 mm with Fenders), you’ll be ready for the roughest roads and even light gravel. If those roads get steep, Allez has a wide gearing range to keep you comfortably spinning so you can ride efficiently. †Alloy disc brake-equipped bikes in the same price range are available at retail. ††Based on production frame set weights. Actual weights may vary slightly. †††Some bikes are shown with an optional rack, fenders, and carbon wheels. - Smooth Shimano shifting with 50-34 chainrings up front and the 11-32 cassette in the rear gives you the versatility to keep up on dynamic group rides or tame the steepest climb on your commute. - 30 mm tires give you the flexibility to run lower pressures – smoothing out rough roads, and a bigger contact patch for more confidence on every ride. - Disc brakes with 160 mm rotors in the front and rear give you more stopping power and modulation in any weather. - A full carbon fork and E5 alloy frame with confidence-inspiring endurance road geometry put you in the perfect position for group rides or solo road adventures. Hidden fender and rack mounts mean Allez can also easily handle your commute to work year-round.

Whether your goal is to escape on gravel back roads, far from cars and crowds, toe the start line at your first gravel race, or simply get the most versatile bike on the road or dirt, no bike is better than the new Diverge. It's quite simply the fastest, most capable - and just maybe the most fun - alloy bike we've ever made, delivering a ride that's quick and lively, but stable and confidence inspiring when the terrain gets rough. With all-new gravel geometry and category leading tire clearance, the new Diverge represents everything we've learned over more than 40 years of riding road, gravel and dirt. The Diverge writes an entirely new chapter in the gravel bike category, so you can dream up entirely new rides. It's the ultimate getaway vehicle. With a premium E5 alloy frame and a full carbon FACT fork the Diverge E5 delivers a fast, confident and comfortable ride on road, in the dirt, and over thick gravel. Shimano's Claris 2x8 group gives a wide range of gears for any terrain, while Axis Elite alloy wheels and Pathfinder Sport 38mm tires provide an efficient ride on pavement with the versatility for hard pack dirt riding. - Nothing unlocks a bike's capability like tire clearance, so we gave the new Diverge a whopping 47mm of tire clearance with a 700c wheel and 2.1-inch with a 650b wheel. Thanks to a drive side chain stay utilizing a machined alloy beam behind the chain rings we've created clearance without using a fragile dropped chain stay design or increasing chain stay length. - Our Premium E5 Aluminum frame provides a stiff, light, and durable platform. When mated to our full carbon FACT fork, the Diverge Base E5 becomes a light, lively and versatile bike ready to attack any surface. - We tossed gravel geometry 'status-quo' out the window. The new Diverge has the most progressive geometry we've ever created for a drop bar bike, giving riders a capable and stable bike in the dirt, that still feels responsive and nimble on the road. We've increased the frame's reach, introduced a slacker head tube and a longer offset fork. All this creates incredible confidence with a planted feeling in the dirt, while spec'ing shorter stems keeps the overall cockpit length the same and the steering lively. We've kept the bike's BB low to increase stability, but high enough to utilize with 650b wheels if that's your jam. - We've given the Diverge plenty of rack mounts, including fork and top tube mounts, to ensure you can take what you need, no matter how far you plan to go, or how long you plan to stay out.
