Assembly Included
Bicycles ordered online will be fulfilled fully assembled through Authorized Giant Retailer. We do not allow our bicycles to be shipped directly to a consumer. There is a $75 destination fee on all non-e-bikes and a $95 destination fee on all e-bikes. Orders may be available for pick up the same day as order submission or may take up to 10 business days to arrive; bikes shipped to your local retailer will need extra time to be assembled.
The price for your bike includes professional assembly by an Authorized Giant Retailer. Your purchase price also includes a basic fitting (seat height, shifter/brake lever positioning) to make sure you’re on the right size bike. If you are looking to really dial in your ride position, many retailers offer more thorough bike fitting systems (Giant Right Ride, etc.) which are not included in the price of bikes purchased through Giant WebLink.
All bicycles purchased through Giant WebLink come with a FREE 30-Day check-up at the local retailer where the order was picked up!
*Note, installation of gear or components is not included in the purchase. Please contact your local retailer for installation costs.

Techs & Features

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.

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.

The D-Fuse seatpost and handlebar were designed to function as a system, absorbing road shocks and vibrations so you can ride farther, faster.

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.

- WeightThe 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.
