An all-rounder on and off the road: Giant Defy Advanced 0

​The Giant Defy Advanced 0 has always been a particularly comfortable endurance racer. In its latest iteration, the bike has further enhanced its versatility for varying terrain.

​The Giant Defy has, almost as a matter of tradition, consistently been crowned the most comfortable bike in its class. Even the most affordable frame variant, the Advanced, is no exception. This is because the carbon seatpost, which is flattened at the rear – a feature Giant first introduced on its comfort models back in 2015 – offers fantastic suspension when extended fully and guarantees top marks in this category. Many manufacturers have copied this design.

Giant Defy: Also suitable for unpaved paths

The more expensive versions Defy Advanced Pro and Advanced SL With an additional taper in the seat tube, they are hardly any more comfortable, but – thanks to better-quality carbon and higher-spec components – they are, above all, lighter. The 32-millimetre-wide tubeless tyres, which appear significantly wider on the rims, further contribute to the test bike’s comfortable ride. However, they need to be meticulously tuned for the effect to be felt. The relatively heavy, thick tyres are difficult to adjust; depending on the tyre pressure, the line between a stiff, bouncy ride and a mushy, sluggish rolling sensation is quite fine. At the very least, their light tread pattern makes them ideal for the occasional ride on unpaved terrain.

The new Defy is lighter

Anyone who doesn’t plan to do this should swap the tyres for faster, high-quality models from established manufacturers, which should make the ride even more enjoyable. The bike can accommodate tyres up to 40 millimetres wide, which also makes it a viable option as a lightweight gravel bike. Apart from that, the bike is well-equipped: the electronic Shimano 105 groupset is paired with relatively lightweight in-house carbon wheelsets. As a result, the model has made a significant leap in the weight rankings, shedding around 200 grams: a Defy with comparable spec that we tested last year weighed 8.4 kilograms.

Low-maintenance and suitable for long-distance use

Although the marathon bike blurs the line between itself and an all-road bike thanks to its generous tyre clearance and comfort-oriented geometry, Giant has omitted other typical features such as a storage compartment or mounting points for a frame bag. Such features are more commonly found on bikes from other manufacturers. The Defy is equipped solely for riding in the rain: a matching set of mudguards, available in two widths for 70 euros, can be screwed onto the designated threads on the frame and fork.

Another appealing feature is how easy the model is to maintain: the handlebars and stem can be replaced without any complicated work, and the stem can be adjusted slightly in height without having to disconnect the brake lines. The riding position on the current Defy is slightly more sporty than on earlier models, but it still meets the requirements of an endurance bike suitable for long distances.

Appropriate translation for ‘mountains’

The only thing that seems a little dated is the wide handlebars, though they do offer a good grip. People with small hands in particular are likely to appreciate the slim upper section of the handlebars, which is pleasantly flattened at the top. We also found the saddle and handlebar tape to be extremely comfortable. In terms of handling, the bike is good-natured and free from surprises; the Defy performs as expected in every situation and rides without a single quirk. On steep climbs, this spec even benefits from a slightly lower gear ratio – though this comes at the cost of slightly larger gear steps on the 11–36 cassette.

Various model variants

The bike now also comes fitted with proper brake discs for descents: Shimano’s IceTech discs reliably harness the full potential of the hydraulic brakes, unlike cheaper variants or alternatives from Tektro, which Giant used to fit frequently as a cost-saving measure. Aerodynamically designed bottle cages and a tubeless kit are included as standard; overall, the bike seems fairly priced. The version with mechanical 105 groupset and aluminium wheels costs €2,699, which we still consider worth recommending. The entry-level model with Shimano’s Cues groupset does not, in our view, justify the saving of a further 400 euros due to its outdated 10-speed drivetrain. At the top end, however, there are no limits, with the Advanced Pro (from 4,999 euros) and the Top-of-the-range Advanced SL model (11,999 euros) A range of features is available, right up to high-end level.
