Defy Advanced 1 Moss Green Information

Season : 2021

Brand : Giant

Code : 2110062GRNGRN

Handcrafted with Advanced Grade composite material the Defy Advanced is engineered with tube shapes that are optimised to absorb road shocks and vibrations.

Even with its smooth ride quality the Defy still delivers a lighweight, stiff and lively feel when you're climbing, accelerating and cornering. It's made with a specific carbon layup to give it an efficient, high performance ride quality that helps you push for new limits in endurance.

The D-Fuse seatpost and handlebar also help reduce road vibrations, adding to its smooth compliant feel on the road. A tubeless Giant wheelsystem and tyres boost speed and efficiency with a reduced risk of flats.

For added control there are integrated disc brakes with flat mounts and 12mm thru-axles.

Road Bike Buyers Guide

When choosing a road bike there are a number of considerations:

  • What type of riding will you do? Are you buying a road bike for a specific use, e.g. commuting or a Triathlon
  • Do you want a carbon frameset or aluminum?
  • Do you want the bike to have disc brakes?
  • Do you want a bike that can be ridden off road too?
  • How much do you want to spend?
We sell a wide range of road bikes from Giant and our womens specific Liv range to suit all uses and budgets. There's no reason why you can't tackle a short course triathlon or sportive while enjoying a speedy commute on one of our aluminum road bikes, but we will always aim to match you with a bike that's right for your needs and budget.

Road bikes generally fall into three categories: endurance, road / race and aero. Giant and Liv offer a bike in each of these categories. If you want a bike that priortises all day comfort in the saddle alongside performance take a look at the Giant Defy and Liv Avail Advanced. Looking for a speedy bike segment in a Triathlon or Ironman? The Giant Propel or Liv Enviliv is the fastest bike in the range. Our all round road & race bikes are the Giant TCR & Liv Langma. Available in a range of specifications and with rim or disc brakes these bikes are at home in the mountains or on group rides with your mates. Bikes with endurance geometry tend to be more upright, while race & aero bikes tend a feature a more agressive riding position.

There's another type of bike that could be an option for you too; Gravel or all-road. Gravel bikes offer off road capability, with increased tyre clearance, specific groupsets and luggage mounting points for adventures on any surface. We also off the Contend & Avail AR ranges with wider tyres and clearance combined with disc brakes that work just as well on city communtes.

Generally there are three materials that are most commonly used as bike frame materials; steel, aluminum and carbon. For many years steel was the main type of tube used on bikes and is still present in some higher end builds today (see our Deanima frames). Steel offers cushioned, comfortable riding feel but bikes made using the material are often heavy. Aluminum is a far lighter material than steel and can be shaped to tune the ride characteristics of the bike. Some cheaper aluminum bikes can feel stiff to ride in comparison to a steel bike. Carbon offers all of the benefits of steel in terms of ride comfort with the lightness (and more) of aluminum. Again the material (lay up) can be shaped to ensure that the frames are compliant in some areas of the ride while maintaining stiffness for power transfer and fast changes of direction. We offer different grades of carbon frame within our ranges. Advanced is our entry level carbon frame that shares the same geometry as the bikes the pros ride but at an affordable price point. Advanced models are available with a range of finishing kit up to Shimano Ultegra 11 speed. Advanced Pro brings in pro level features like the double oversize Overdrive Two head tube that improves stiffness and direction changes alongside an increase in specification that includes carbon wheels as standard. The Advanced Pro bikes can also be purchased with electronic shifting from Shimano or SRAM AXS depending on the model chosen. Finally, there are selected models available in Advanced SL carbon. This is the carbon that riders like Tom Dumoulin, Marianne Vos and Greg Avermaet have ridden to victory in the grand tours and Olympic games and represent the pinnacle of frame technology.

Disc brakes are becoming more and more common on road bikes. Disc brakes offer improved stopping performance in all conditions, particularly if they are full hydraulic versions. They need less maintainence than rim (also known as caliper) brakes but there is a trade off in increased weight in comparison to caliper brake models and pads will generally cost more to replace. Disc brakes use a rotor as the braking surface, rather than the rim of the wheel. This increases the life of the wheelset supplied with the bike. Disc brakes work particularly well with carbon wheels as there are no issues with heat on the braking surface and bikes with carbon rims take longer to stop in wet conditions.

Gravel bikes are becoming more popular and we have aluminum and carbon offerings across the Giant and Liv ranges. In addition to the Contend and Avail AR we have the Giant Revolt and Liv Devote. Both of these models can be bought with a carbon or aluminum frame depending on your budget. All of the bikes feature disc brakes and luggage mounting points. They're a great choice for one bike to do it all.

Our road ranges start from around £700 with the Giant Contend and Liv Avail. Carbon bikes (for 2021) start from £1799. Giant and Liv bikes feature industry leading frame technology that transfers into a fantastic riding experience on the road. We always recommend going for the best frame you can afford; everything else can always be upgraded. Giant carbon bikes come with the frame finishing kit that will allow an upgrade to electronic shifting for example.
