The Libre CR is getting a big upgrade with Shimano's GRX 600 2x11 drivetrain. Shifting is smoother than ever and the wide gear range makes any mountain a mole hill. The Kona Race Light Carbon frame features a ton of mounts for carrying just about anything. Paired with Kona's Verso carbon fork and its 3pack cage mounts, this bike is a seriously lightweight gear-hauler. Whether bikepacking, ripping the local gravel roads, or out on an epic summertime century, the Libre is fast, efficient, and comfortable across any terrain. Kona Carbon Designed to be lightweight and built to demanding standards. Carbon fiber has long been praised for its weight and strength, but rather than chase grams, we place our efforts on the performance that is possible when the right high-modulus fibers are in the right places. Our designers work very closely with our manufacturer to ensure there is no compromise to the desired ride characteristics, durability and – finally – weight stipulations that we expect from our bikes. Integrated Headset Integrated headsets are simple, light, and effective headset systems whereby the bearing race cups are actually part of the head tube, and they are either machined away and left with the head tube, bonded (carbon), or welded in with steel or alloy. Like an internal headset, an integrated headset also reduces stack height, so the height of the stem and bars are more adjustable, giving the rider the best fit possible. 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. 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.

How do you improve on a bike that already feels pretty damn close to perfect? Steel seemed like a solid move. Helping to smooth out your ride and turn heads, the Rove DL (formerly called the Rove ST) features a stunning Kona Butted Cromoly frame and Project Two Cromoly Disc fork. A reliable SRAM Rival 1x11 drivetrain and TRP Spyre C brakes ensure the bike functions as nicely as it looks. The all-new Rove DL is running on WTB KOM Light Team i23 TCS rims wrapped in WTB Venture TCS 47mm tires, making it ready for anything! 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.

The Sutra ULTD is the continuation of a dream to make a drop bar bike as badass as possible. The butted Cromoly frame and Project Two Cromoly disc fork hold WTB KOM Light Team i27 TCS 2.0 rims on Maxxis Recon Race EXO TR 29x2.25" tires. That’s right. 2.25" of earth-gripping rubber. When the descents get hairy, you can get low with a Trans-X +RAD dropper post. SRAM Rival 1 flat mount disc brakes and drivetrain keep things moving (and stopping) nicely. This bike is as beautiful as it is beastly, with a gorgeous Prism paint job. Turn heads while you turn over the miles on the brand-new Sutra Unlimited.

The Unit X has become a cult favorite among die-hard Kona fans. Maybe it’s the Cromoly frame. Maybe it’s the fact that it’s a bikepacking monster, or its SRAM SX Eagle 12-speed drivetrain, or modular dropouts which give you the ability to run it as a single speed if that’s your thing. Maybe it’s because the rigid fork makes it that much more of a classic. We may never know why the Unit X is such a popular bike, but we can only guess it’s because it is one of the most practical machines in our lineup. Reynolds 520 Cromoly Reynolds 520 tubes are mandrel-butted for accurate profiles and available in a wide range of shapes. Weight savings from butting provides competitively priced, light framesets that are noticeably compliant on the road or the trail, and are guaranteed to last a lifetime. Internal Headset Bearing cups are actually pressed into the frame and are easily removable. An internal headset also reduces stack height, so the height of the stem and bars are more adjustable, giving the rider the best fit possible. 44mm Head Tube 44mm oversized heatubes allow us to run tapered steerer forks by using a large external lower cup headset bearing. The larger diameter steerer tube adds considerable stiffness and will increase responsiveness to the front end, improving all-around performance. 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. 12x148mm 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.

Every Jamis youth bike uses size-specific items like grips, saddles and cranks that enhance comfort and control by providing the best possible bike fit. We focus on designing frames with low stand-over’s to take much of the awkwardness out of getting on board and dismounting after. We trim as much weight as we can with lightweight aluminum frames on many of the youth models and use aluminum parts where possible (the limiting factor here is working within a youth bike appropriate price point) to work towards that make-it-as-light-as-possible goal.

Your little one will learn balance quicker than ever with Specialized's Hotwalk. It uses a lightweight, aluminum frame with an extremely low standover height so they have plenty of room to use their feet to propel themselves, while the comfy seat lets them sit down and coast when up to speed. The kid-friendly Hotwalk geometry makes this a perfect bike to introduce your child to the wonderful world of bicycling.

TOP FIVE THINGS YOU NEED TO KNOW Laser's mini MX-Moto design offers plenty of stand-over clearance for young riders and a head-turning, two-tone paint finish that will be the talk of the neighborhood. The over-sized blades and leading axle dropout of the Laser fork assures it will be up to the task of getting there and back safely. If a steel or alloy part is not painted or anodized, we protect it with a black electro-plating which enhances the corrosion resistance of that part. The satin sheen of the finish looks good too. The Laser's full-length & full ring-wrap chainguard keep clothes & legs cleanly and safely out of the way of the chain. Every 16” Laser offers stabilizing training wheels that assist the young rider in learning how to pedal, steer and balance a bike for the first time. The training wheel support struts attach securely both to the rear hub axle and the frame itself so that the training wheels don’t rotate out of plane with the rear wheel, preventing tips or spills.

TOP FIVE THINGS YOU NEED TO KNOW Our lightweight & durable aluminum Laser frame is easier to pedal than steel. The 20” Laser actually offers two types of brakes: a standard rear coaster brake, which most youngsters are familiar with, and a rear V-brake which many are not. Having the rear coaster brake as a back-up, allows youngsters to get used to hand-braking without going cold-turkey on the coaster brake they are comfortable with. Our alloy rims are anodized black to provide even greater corrosion and rust resistance than the alloy already possesses. Before wheels are laced and trued, the rim sidewalls are ground to provide a smooth braking surface for the rear V-brake. We build the Laser 2.0 wheels with 36 spokes in a 3-cross lacing pattern for a strong & durable wheel. Then mount knobby BMX tires that bite in the dirt, but also feature a rounded profile that rolls smoothly on neighborhood streets & driveways. Every Laser 2.0 offers a kickstand for parking that pride & joy up securely, and a safety bell to announce that the Laser has arrived.
