The new Seek was created for one reason: to transform the road riding experience for kids and give them the same feeling of speed, efficiency and control that adult road riders enjoy. To achieve this, we designed, developed and purpose-built a new range of bikes that stands apart from previous Giant youth road bikes and sets a new standard in the category.

A lightweight ALUXX frame with a composite fork and smaller diameter Giant SLR 650b Composite WheelSystem makes the Seek a light and agile road bike designed specifically for young riders. Youth-optimized components, including shorter reach handlebars and brake levers along with shorter 130mm cranks and a narrow 125mm wide Giant Grit Core Lite saddle, offer greater control and comfort for young riders looking to grow and expand their road riding capabilities.

Key Performance Factors

LIGHT AND AGILE

The Seek features a lightweight ALUXX aluminum frame designed with smaller diameter frame tubing specifically for young riders. The frame and composite fork which adds road-smoothing compliance and precise steering control work together to produce a dynamic ride quality.

YOUTH- OPTIMIZED COMPONENTS

The cockpit is designed to give smaller riders greater efficiency and control on the road. The Giant Contact SL Lite handlebar is specially shaped with a shorter reach (62mm) and drops (100mm) compared to typical adult bars. The brake levers are also designed for smaller hands with a reach that’s 35% shorter from the drops and 30% shorter from the hoods. The outer hood diameter is 20% smaller and the lever’s flared shape improves ergonomics for small hands.

EFFORTLESS FIT

Designed for kids 130-150cm tall Seek makes it easy to dial in a perfect fit and make adjustments as the young rider grows taller and gains more experience with road riding. From first timers to junior road racers it’s an adaptable road bike that evolves with the rider. Beyond the purpose-built frameset designed with smaller diameter tubing the Seek features a seatpost that’s marked with a body height index making saddle height adjustment intuitive and simple.

Advanced Composite Technology

Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.

ALUXX Aluminium Technology

This Performance level frame material features 6061 alloy with single-butted tubes to produce strong lightweight framesets for a variety of different bikes and riding styles.

Compact Road Design

Introduced by Giant with the professional Team ONCE in the 1990s Compact Road revolutionized the look and feel of high-performance road bikes forever. A downward sloping toptube (from the headtube to the seattube) creates smaller front and rear triangles for a lighter stiffer bike. It also makes it easier for riders of all sizes to have a perfect fit.

D-Fuse Seatpost

The proprietary “D” shaped composite seatpost damps vibration resulting in a smooth compliant ride.

OverDrive

Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper for road 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.

PowerCore

A massively oversized bottom-bracket/chainstay area features a fully integrated 86-millimeter wide bottom-bracket design (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.

Tubeless System

Fewer flat tires. Greater traction. Less rolling resistance and a smoother faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.

Weight	The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight but in reality weight can vary based on size finish hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.

Every effort has been made to ensure accuracy throughout this website. However Giant reserves the right to change bike specifications features prices and colours without prior notice.
