With bigger bikes come bigger demands. The new Domain takes cues from ZEB, our enduro specialist fork with serious credentials. Domain offers a new burly 38mm chassis, short fender compatibility, and a confidence-inspiring DebonAir air spring matched with a reliable Motion Control RC damper. We even brought the performance of Maxima Plush damping fluid along for the ride. Nothing goes as big as Domain does in value and performance. - 38mm chassis for increased stiffness and rider confidence - Motion Control RC damper featuring low speed compression adjust with externally adjustable dual-flow rebound - Highly tunable DebonAir air spring offers a consistent feel throughout the travel - Maxima Plush damping fluid reduces friction and quiets damper noise - Short fender compatible. RockShox premium fender sold separately. AM Variants include RockShox zip-tie fender - Fits tires up to 2.8" without fenders—use of any fender may reduce tire clearance

The new Record 12x2 Speed crankset: a new hole-free design for the right-hand crank that optimizes aerodynamics. The new carbon fiber Record 12x2 Speed crankset with unidirectional finishing guarantees continuity with the finishing of the entire groupset, whilst maintaining the Ultra-Torque bracket system on the steel axle to ensure perfect transmission of power. The new Record 12x2 Speed crankset can be installed on any type of frame, whether or not it is being used with disc brakes because it optimizes the chain line on the frame with a rear hub flange measuring 130, 135 or 142 millimeters without affecting the Q factor that remains constant at 145.5 millimeters. The innovative design of the outer chainring ensures faster, quieter derailing owing to the contoured pin. The symmetrical design of the inner chainring teeth allows improved stability with chain crossovers. The double wheel sizing standards (112 and 145 millimeters) enable reducing the weight through greater use of carbon fiber. There are eight fixing screws for increased structural stiffness. The varying number of pins for each of the three chainring combinations (34/50, 36/52, 39/53) facilitates upshifting due to the optimized free strokes associated with each combination. The special drains on the inside of the outer chainrings optimize performance when downshifting in dead spots.

Kids move fast, and grow faster. At times, it can seem like there's a small window for the perfect bike fit. The right bike for a young rider is a delicate balance between too small, too big, and a short-lived just right. If we're going to inspire the next generation of riders, we need to keep kids comfortably riding longer. The Jett is designed so that you'll never fear the growth spurts. We did our homework to understand how kids grow—spoiler alert, kids' arms and legs grow more rapidly than their torso. We took to the books and designed a bike with child-specific touch points that withstand the development of young riders. The Jett is uniquely adjustable, perfectly proportional, and child-liftable—they'll always be set to Jett. The Jett Multispeed features an adjustable handlebar that allows kids to fine tune reach as their arms grow. The 2-hole position cranks combined with longer seat tubes give plenty of flexibility to dial-in the optimal pedaling position. And what's more, we designed the frame and reviewed every component to make the Jett one of the lightest bikes on the market. You're going to have to beg them to get off this bike. - We designed the Jett Multispeed to be uniquely adjustable with 2-hole position cranks, adjustable handlebars, and longer seatposts so kids can dial-in the perfect riding position as they grow. - Every detail of the Jett Multispeed—including the 130mm Bridge saddle, narrower-diameter grips, and short-reach, tool-less adjustable brake levers—was informed by Retul data from a kids' research group to be perfectly proportional for young riders. - A lightweight bike is simply more fun and the Jett Multispeed's all-new A1 aluminum frame, alloy fork, Pathfinder tires, and 8-speed drivetrain make it one of the lightest kids' bikes on the market.

SUITO-T is the Elite Suito home trainer without supplied sprocket cassette, a powerful and compact model that offers total compatibility with several types of bicycle. Powerful, solid, and quiet, SUITO-T is an interactive home trainer designed to offer a realistic, accurate, and fun bicycle workout experience. Featuring direct transmission to ensure increased accuracy and quietness while working out, the SUITO-T is very stable trainer even during the most intense sprints, and its small size makes it easy to transport and store everywhere. What's the difference between a Suito and a Suito-T? - SUITO and SUITO-T are two identical home trainers, featuring the same technical specifications both in terms of structural and electronic features. - What separates them is the sprocket cassette, which is included in the Suito but not included in the SUITO-T. Compact design - The main feature of this home trainer is the sturdy steel structure, ideal to ensure durability and stability even during intense sprints. - Featuring an elegant and solid profile, SUITO-T has a wide support base with pre-assembled support legs. Just position them properly to trigger the automatic lock mechanism. - SUITO-T is designed to ensure a small footprint wherever you go: its integrated handle, reduced size, and slim profile makes it easy to transport and store everywhere without worrying about its footprint. - SUITO-T optimized design makes it compatible with various bicycle models and commercially available sprocket sets. Accurate and powerful bicycle workouts - SUITO-T simulates gradients up to 15% with ± 2.5% accuracy, one of the most powerful home trainers you can use to release all your power even during the most intense sprints. The following functions also contribute in displaying accurate workout data: - Power Meter Link (PML): It's a function that lets the home trainer employ an ergometer that's already installed on your bike as a power source. - Spindown: A calibration procedure for the home trainer that takes into account all friction values that change over time and during use that influence brake's accuracy and compensates its effects on the resistance generated by the home trainer. - Temperature compensation algorithm: A function that lets the home trainer compensate the variations due to brake overheating and take the resulting data into account when calculating power. Train on Zwift and My E-Training! - Discover all the software you can use with SUITO-T: other than Zwift and My E-Training, you can also manage it with all other indoor cycling platforms such as TrainerRoad, Kinomap, Rouvy, Bkool, Bikevo and many more. - SUITO-T adds up to the Elite home trainers' range of ANT+ FE-C & Bluetooth home trainers that interact with every app, software, computer and device (smartphones and tablets) via iOS, Android, MacOS and Windows. Just choose the software, select the course or training program and start pedaling on your bike. SUITO-T will automatically adjust resistance. Sensorless cadence - All home trainers by Elite immediately send power, speed, and cadence data, thus setting themselves as effective instruments to build an accurate training program and replicated outdoor workouts as much as possible. Cadence is measured via a practical sensorless technology (that is, no sensors to apply to your bicycle) and is calculated on the SUITO-T as a function of speed variations.
