2015 Giant Defy 1 Road Bike with ALUXX SL-grade aluminum and Composite, Alloy OverDrive steerer

 

The 2015 Giant Defy 1 - So much road bike for such an affordable price

The bicycle industry is talking about the Defy. While most of the attention is on the $10,000 pro model, the good news for the rest of us is that the Alloy version of this bike includes all of the engineering wizardry of the higher priced bikes.

The frame design of the Defy has been winning accolades for years, and the design wasn't changed for the 2015. But improvements were made throughout the bike. In particular the frame tubing is far and away best in class.

In fact, the entire bicycle industry has made massive strides in the construction of aluminum alloy frames, bringing them dangerously close to parity with carbon fiber. Giant, who owns their own factories and forms their own aluminum tubing is at the forefront of this technological revolution with Aluxx alloy tubing. And the Defy is outfitted with SL grade alloy.

ALUXX ADVANTAGE

From the manipulation of atomic grain structures to our advanced forming and welding techniques, Giant has been at the forefront of aluminum engineering for more than 30 years. Today, ALUXX Aluminum Technology represents the pinnacle of alloy performance.

A heritage of craftsmanship combined with unmatched manufacturing capabilities gives Giant the unique ability to monitor every step of the aluminum frame-building process. Through our
cutting-edge materials science, proprietary forming techniques, and attention to detail, we are constantly advancing aluminum performance to create bikes that are lighter, stronger and stiffer. The difference can be felt in the ride. Every aluminum bike bearing the ALUXX Aluminum Technology label must live up to the highest standards and meet the tightest tolerances of any aluminum frame in the world. Here is the skinny:

---

Giant's lightest, state-of-the-art aluminum frameset technology featuring our highest strength-to-weight ratios, most advanced forming methods, and unique welding techniques

Materials

• Exclusively features 6011A alloy for unprecedented strength-to-weight ratio

Forming methods

• State-of-the-art butting results in 20 percent thinner (and lighter) tubes than ALUXX SL
• Features extensive FluidForming (sophisticated manipulation of tubeset shaping via an injection of high-pressure fluid) and some PressForming (basic manipulation of tubeset shaping via direct mechanical pressure)

Welding techniques

Features both Smooth (double-pass weld technique with hand-sanding to reduce stress risers) and Slim (custom-fit tube junctures to decrease weld material) welding techniques for minimal weight, maximum strength and the cleanest aesthetics

The defy one offers the best components package of any bike in this class.
