Summary

The Giant Defy is celebrated for its versatility and comfort, making it an excellent choice for endurance road riding. It excels in long-distance comfort with features like the D-Fuse seatpost and handlebar, while maintaining a lively and stiff ride quality. Reviews highlight its ability to handle both fast club rides and gran fondos with ease, though some note a twitchy front end without proper fit.

Pros
  • Versatile for different types of road riding

  • Comfortable for long rides

  • Fun to take on fast club rides and gran fondos

  • Lively and stiff

  • D-Fuse handlebar and seatpost improve comfort

Cons
  • Stealth Stem could frustrate do-it-yourself bike fitters

  • Somewhat twitchy front end without proper fit

  • Cable routing is messy and rattles

Key Quotes
The goal with the Giant Defy range of bikes was to create a line that was more versatile, something that worked well for different types of road riding.
Canadian Cycling Magazine logoCanadian Cycling Magazine
The D-Fuse bar certainly helped to reduce the impact of larger bumps and the overall chatter from the less-than-ideal road conditions.
Canadian Cycling Magazine logoCanadian Cycling Magazine
It almost perfectly balances performance and comfort and the spec list at this price point is almost unbeatable.
Cycling Weekly logoCycling Weekly
The Giant Defy Advanced 2 is very close to the perfect bike for the type of riding that the more reflective riders among us have been doing recently.
Cyclist logoCyclist
As an endurance bike, the Defy is pretty much flawless.

  • Decent tyre clearance

  • Geometry gives smooth handling

  • Well priced

Lows

Jun 2019 · Warren Rossiter

What’s allowed Giant to spec such a premium drivetrain is the mix ‘n’ match nature of this bike’s braking system, which is made up of Giant’s own Conduct hydraulic disc brakes hooked up to the cable-actuated Ultegra brake levers.. .

Highs
  • Smooth ride, great position and good value with it

Lows
  • The cable-hydraulic brake system lacks feel and adds weight up front

Jul 2018 · James Huang

Giant’s previous-generation Defy range broke new ground in 2014 by being the first complete range of endurance road bikes from a major manufacturer to exclusively offer disc brakes.
