Giant’s award-winning Defy range features three different series—Defy Advanced SL, Defy Advanced Pro and Defy Advanced. All models are crafted with a lightweight composite frame and fork and proprietary D-Fuse handlebar and seatpost technologies to absorb road vibrations. They also feature internal cable routing and disc-brake integration.

An endurance road bike can comfortably handle rougher roads and some gravel or dirt sectors, but it’s not typically made to accommodate the larger tire widths required for loose or chunky gravel.

A road racing bike is built for speed, which demands a lower, more aggressive position, while an endurance bike has a more upright and relaxed position. Racing bikes are oriented toward efficiency and performance, while endurance road bikes prioritize comfort and are better suited to longer rides when the pace is less intense.

Endurance road bikes typically have generous tire clearance allowing for wide rims and high-volume tubeless tires to absorb the road’s imperfections.
