Steel Commuter and Gravel Bike Preamble is a hard-boiled steel commuter built for comfort, durability, and buffoonery on pavement and gravel. Nothing More is Needed. Nothing Less Will Do. The challenge was thus: Build a serious steel bike and give it only the attributes that matter most. Make it quick and comfortable on pavement, as well as confident and compliant on degraded surfaces. What the Enginerds put forth is Preamble, a pavement and gravel utility worker that proves you don't need to cut corners or clip coupons to make a more affordable steel bike. You just need to keep shit simple. Preamble can run racks and fenders and carry a couple water bottles. Surly was raised on stealing basic cable, after all. Smooth and efficient on asphalt, Preamble's double-butted main triangle provides a resplendent ride feel and withstands abuse from life's inevitable potholes. Make it your own with flat bars, drop bars, a basket, or bags. On the road to steel euphoria, Preamble is the gateway drug. Let facts be submitted to a candid world: - Offered in flat-bar and drop-bar configurations - Easy T-Shirt sizing to fit nearly every rider (XS, S, M, L, XL) - Sloping top tubes on XS and Small frames for improved standover and comfort - To offer the best rider experience for every frame size, XS and S frames get 650b wheelsets while M–XL get 700c - Custom-cast single-position vertical dropout

Designed to introduce unfamiliar riders to Surly’s pavement and gravel line, Preamble highlights Surly’s most essential features: Durable custom steel tubing, a renowned ride feel, and just the right mounts for running racks, fenders, and bottle cages. Available in flat-bar and drop-bar configurations, it’s disc-brake specific and shares a single-position vertical dropout with Surly Bridge Club. For new weekend riders and veteran commuters, Preamble makes it easier than ever to get out of the car and on top of tough and comfortable Chromoly steel. - 100% Surly Chromoly steel frame and fork; double-butted main triangle - Five frame sizes to fit nearly every size rider (XS, S, M, L, XL), with a slightly sloped top tube on XS and Small frames for improved standover and comfort - Friendly with 1x and 2x drivetrains - Mounts for racks, fenders, and two bottle cages (located on the seat tube and down tube) - Clearance for 650b x 41mm tires on XS–S frame sizes (650b x 38mm with fenders); 700c x 41mm tires on M–XL frame sizes (700c x 38mm with fenders)

Straggler is a bikepacking-inspired road/gravel bike mostly at home on pavement but ready for trail duty when called. Born on Gravel. Raised on Pavement Straggler is tuned for cross-over exploration on a wide variety of terrain conditions. It's a day-tripper and a weekender. It's a "rough road" road bike, a cyclocross bike with no pretense about racing, a utilitarian townie, a light-duty touring bike and an all-weather commuter. It's a steel gravel bicycle that thrives on the road. Think of it as a "mountain biker's road bike." If you only have room for one bike in your life, Straggler can (and should) be your one and only. Straggler's capabilities go well beyond asphalt. It also lends itself well to light touring setups. We're talking frame bags, seat bags, and "credit card touring" rather than full-blown touring. Straggler also handles our 8- and 24-Pack Racks well, so you have some heavier-duty loading options. - Accommodations for racks and fenders - Forward-exiting horizontal dropouts for singlespeed compatibility and wheelbase adjustability - Clearance for 650B x 41mm tires with fenders!

The Crux DSW is more than the lightest alloy gravel bike ever made. We took everything we learned creating the carbon Crux and used our patented D’Aluisio Smartweld to make it a reality in alloy. We’ve created the most capable, nimble, balanced, and responsive alloy gravel bike ever made for fast, fun, high-performance riding. And yeah, it’s the lightest too. Some may call it a carbon copy, but we call it the Crux DSW. Lightest Weight At just 1399 grams*, the Crux DSW is the lightest alloy gravel frame in the world. Combine that with our Fact12r Crux carbon fork and a build curated for performance, and a complete Crux DSW tips the scales at 9.37kg—no alloy gravel bike can compete. *56cm in the lightest colorway. Production frames will vary. Most Capable More clearance means more capability—that’s why the Crux DSW has the same tire clearance as its carbon sibling—47mm and up to 2.1” on a 650b wheel. Combine this with the tough and light alloy frame, and Crux DSW can take you anywhere you imagine at full gas. Ultra-Responsive Responsive at the pedals. Supple in the saddle. We’ve used D’Aluisio Smartweld to fine-tune the properties of alloy to deliver a ride previously impossible without carbon and combine it with the same performance gravel geometry and race-influenced fit as the carbon Crux. A longer reach delivers better weight distribution for quick, confident handling, while a lower stack creates a performance first position. At 72mm of bottom-bracket drop, we hit the sweet spot between nimble and stable. D’Aluisio Smartweld D’Aluisio Smartweld - or DSW - is a patented engineering process that uses hydroforming to precisely match tube-to-tube joints for better, stronger welds and, ultimately, a lighter frame that can be twice as durable as a traditional alloy frame. Our Smartweld technique helps us create a unique single-piece downtube and bottom bracket for the Crux, shaving weight and amplifying responsiveness. - Lightest: 1399g Crux DSW Frame (raw, unpainted).

Snuggle up. - With tire clearance up to 38c/40mm, this endurance road machine delivers better traction than ever on rough roads and even light gravel. Thanks to lightweight, super-efficient Specialized tires, that extra tire volume and traction comes with no downsides. - Roubaix inspires really BIG days on the bike, so we've given it every mount your adventures could need- three bottle mounts, top-tube mounts, and it's even fender-ready. So, go ahead and bring it all along for the ride. - PERFORMANCE: The new Roubaix SL8 is our most aero yet, with new aero shapes from our Free Foil library and dropped seat stays. At just 825 grams, the frame is 50 grams lighter, utilizing lessons learned from the Aethos—the world's lightest production frame—and our premium Fact 12r carbon blend. Nothing in its class is faster or lighter than the Roubaix.

Nothing is faster than the Tarmac SL8 thanks to a combination of aerodynamics, lightweight, and ride quality previously thought impossible. After eight generations and over two decades of development, it’s more than the fastest Tarmac ever - it’s the world’s fastest race bike. Your legs up for it? Aerodynamics or lightweight alone don’t win races - speed is what matters. Delivering that speed requires creating an uncompromising combination of aerodynamics, lightweight, stiffness, and compliance. Through race simulations using real world data our Ride Science team knows the Tarmac SL8 is the fastest race bike ever made on the routes that matter - 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the legendary Tourmalet climb. - AERO IN EVERYTHING: We’re putting aero where it matters - the leading edge - not just where it looks good. In the process we’ve created our most aerodynamic road bike ever. Yes, it’s more aero than the Venge. Clean air is optimized for maximum advantage with the Tarmac’s new nose cone - the Speed Sniffer. By moving the steer tube back - the tube that determines head tube width - the leading edge of the head tube can be much sharper, delivering a much lower drag shape. Utilizing new UCI rules, the Tarmac SL8 has the narrowest, most aero seat post we’ve ever made ensuring fast-moving, dirty air around the legs can flow back more cleanly. Doesn’t victory smell sweet? - MINIMUM WEIGHT, MAXIMUM AERO: Tarmac SL8 took learnings from Aethos to be easily built at the UCI minimum with a full aero set up. The team delivered a mind bending, scale tickling 685 gram frame - 15% lighter than the Tarmac SL7 and lighter than anything on else on the World Tour*. With the ability to make lightweight a top priority in the down tube, seat tube, and rear of the bike lessons from Aethos were applied. The frame’s shape carries load so efficiently that extra carbon stiffness layers become redundant. *Unless of course you count the time Kasper Asgreen raced our 585 gram Aethos frame during a Tour stage. - GOES LIKE HELL, RIDES LIKE HEAVEN: With massive gains in stiffness-to-weight - an improvement of 33% over the SL7 - the Tarmac SL8 takes legendary handling, aggressive responsiveness and World Championship proven geometry to the next level. The bike is stiffer at the pedals, more precise at the bars, and combines it with a compliant ride in the saddle that sets a new benchmark for race bike comfort. Thanks to our Rider-First Engineering, every rider, regardless of size, gets the same unprecedented ride quality and handling. In the saddle the Tarmac SL8 delivers 6% more compliance, floating over rough road with a supple feel unique in the high strung world of race bikes. Tarmac’s proven geometry and 32mm tire clearance are identical to the SL7, ensuring easy adaptation and the versatility to run higher volume tires when needed. - BEYOND GENDER: There can be more difference between two male cyclists than between a male and female. Gender alone doesn’t provide nearly enough data to specialize and that means creating male or female bikes is arbitrary and outdated. Every rider can get the next-level advantage of Tarmac SL8. It’s time to go Beyond Gender. - The Tarmac SL8 Expert delivers exceptional performance with a full SRAM Rival eTap AXS groupset with power meter, C38 carbon tubeless ready wheelset, and an SL7 stem with Specialized Expert Shallow Drop alloy handlebars makes for an accessible performance-packed bike.

THE LIGHTEST AND MOST CAPABLE RACING BIKE Performance, technology, and style have always been cornerstones of cycling. We may not compete but we love the feel of a racing bike – an Orca that is light, fast, and beautiful. Professional athletes, weekend warriors, Strava hunters, and recreational riders all have similar aspirations – we love the machine as much as the lifestyle. ICR Internal Cable Routing is carefully routed along the best path under the stem and through the head tube, with no rub or rattle, and is optimized for both traditional and electronic shifting systems. HIDDEN CLAMP Orca's seat post clamp is smoothly integrated into the frame, decreasing the likelihood of contamination and increasing aerodynamics. Not to mention, it looks great too. SEATPOST CLAMP The sleek and secure clamp of the Orca seat post is a proprietary design that allows tilt adjustments to be made independently of the saddle fore-aft position. INTEGRATION Cables and brake hoses are routed directly inside the stem under an aero cover. A clever headset design and split stem spacers allow the cables to enter the frame while still permitting stem adjustment.

The Rove has become the go-to bike for people all over the world that are itching to just...go! It's spec'd just right, is easy on the eyes—the Rove makes quick work of the commute, gravel trail, or the after-work fitness lap on your local hill. The Rove is the elusive 650x47c steel bike that you can afford. It was cool before cool was cool. It is a bike that wants to ride anywhere YOU want to ride. KONA CROMOLY Very few materials offer as much shock absorption, durability and supple-ride characteristics as steel. We've never strayed from cycling's original material and have worked tirelessly to adapt, refine and innovate Kona Cromoly framesets as rider demands continue to evolve. TAPERED HEAD TUBE More girth at the bottom of the head tube better distributes shock force, prolonging the bearing life of the headset itself and eliminating brake shudder, while providing confident steering performance. The inherent strength of its triangular design also means a stronger steering position and improved balance, giving the rider more control in rough terrain. A zero-stack, tapered head tube also puts strength where the load is going—into the lower headset cup—maximizing bearing durability where it's needed. TUBELESS COMPATIBLE RIMS Tubeless rims allow for tires with more puncture resistance; the ability to run lower tire pressure, which provides better tire grip on the trail; lower rolling resistance; and weight savings over traditional tube and tire systems. 12x142mm AXLE 12x142mm, 12x148 and 12x157 rear axle standards provide two major advantages to the Kona rider: the 12mm diameter of the rear axle provides the rear hub and frame with a stiff interface, while the 142/148/157mm outer diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted. For 2017, you'll see the 12x148 Boost standard in the mix. Boost spacing provides more tire clearance at the chainstay yoke, while the rear wheel is stiffer and more durable relative to a 12x142 thru-axle. 650b WHEELS 650b wheels and tires have a similar overall diameter to a traditional 700c gravel or commuting tire, but with a smaller diameter rim and a wider, taller tire. The extra air volume in this new generation of urban and mixed-surface tires means they can be run comfortably at lower pressures while still rolling quickly on a variety of surfaces. It's the best of both worlds.
