Road Bikes

Our Core-Line fixed gear and single speed bicycles are what we're best known for. Built on a durable steel frame with seatstay rack mounts, eyelet mounts on the fork, and cable stops, the Core Line models are as stylish as they are versatile. Quality components, a flip-flop hub that allows you to ride fixed gear or freewheel, and comfortable grips will keep you riding hassle-free for years to come.

The 4130 Steel Line earned its namesake from the double-butted 4130-grade chromoly steel used on the frame and fork that maximizes strength without making compromises on weight. Internal cable routing, seat stay rack mounts, water bottle cage mounts, a flip-flop hub, and integrated chain tensioners provide versatility while maintaining the clean aesthetic State Bicycle Co. is known for. Drilled high-flange hubs, an open faceplate stem, and the CNC'd seat post clamp not only look great but also help to shave some additional weight. The latest 4130 Steel Line models feature a subtle but stylish 'STATE' logo on the down tube and an updated 'SBC' head tube logo. The ability to customize your bike by selecting your handlebar style and wheel set all combine to make sure you have a bike as unique as you are.

All too often, corners are cut to meet price-points in the entry-level road bike market, but the Allez redefines what it means to be "entry level." Focusing on weight, refinement, and reliability like nothing else in its class, the Allez is the first to make these technologies accessible to everyone. Whether you're just getting into road cycling, commuting, or looking for a new bike, the Allez is just as performance-packed as it is versatile. For the build, this Allez features reliable Shimano Claris shifting, durable Axis Sport alloy wheels, our new super-comfy Body Geometry Bridge saddle, and well-protected RoadSport tires. - Not only does a lightweight bike feel better when you're climbing up a hill, but it's also essential when you're carrying your bike up to the 5th floor, and this was at the forefront of the frame design. With a redesigned E5 Alloy frame, the Allez features a class-leading weight. Aggressively thin-walled, yet tough, tubes have been implemented to save weight and this results in over a 450g (1-pound) reduction in the frame and fork alone when compared to some models of yesteryear - Entry-level road bikes often times feature either alloy or cheap carbon fiber forks that greatly detract from the overall ride quality. But with a full FACT carbon fiber fork, the Allez is better handling, smoother riding, and lower in weight, floating over rough chip-seal and carving through corners like a slalom skier. - For the geometry, we developed the Allez by utilizing our vast Retul fit database. This meant creating a geometry that's sure to cover a broad range of positions, while still providing the performance-minded handling you'd expect from your first bike. - This Allez also features integrated rack and fender mounts, allowing you to get weight of your backpack off you and onto a lightweight rack. This not only makes for a good road bike, but it also enables you to transform it into a fast commuter.

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.

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.
