Eight disc-equipped and six non-disc models starting from £499 revealed in Giant's 2015 Defy range

This summer Giant Bicycles lifted the lid of their brand new Defy endurance/sportive bike. Completely redesigned with a new carbon frame incorporating disc brakes, the new bike signaled a bold new direction for the company. The disc range starts at £1,199 and tops out at £7,999, all featuring carbon frames. There will also be five aluminum non-disc models priced from £499 up to £999.

We got a first look at the new disc bike and even got to ride the top-end model and came away very impressed. The Defy is Giant’s best-selling bike and the only aspect to carry over into the new model is the geometry, everything else has changed. The carbon model uses a new D-Fuse seatmast (or seatpost on lower models) designed to improve ride comfort, along with super skinny seatstays and a slender top tube.

The biggest news though is that the carbon Defy bikes are only being offered with disc brakes. Giant felt the time was right to make the switch, saying it suits the potential customers and the type of riding they’re doing with the Defy. Making this commitment allowed Giant to shed quite a bit of weight from the frame in the process, with a claimed 890g weight for a medium.

Giant have taken a pragmatic view towards thru-axles, the oversize axles common on mountain bikes that some manufacturers are using on disc road bikes, and stuck with regular quick releases, as this offers greater wheel choice at this stage in the development of the disc road bike.

And if disc brakes aren't your cup of tea, there are a range of aluminium Defy bikes without disc brakes.

Giant have now revealed the full range of 2015 bikes and prices for each model. There will be eight Advanced models with a carbon fibre range priced from £1,199 to £7,999, each with disc brakes. The aluminium Defy without disc brakes will number six models costing £499 to £999. Let’s take a closer look. While the specifications here are correct, there may be some changes to paint jobs and colour options when the bikes hit the showroom floor later this year.

Defy Advanced SL 0 £7,999

This is the range-topping model and the one road.cc rode at the worldwide launch in Scotland earlier this year. It has the same Zipp 202 wheels with Shimano Dura-Ace Di2 groupset with R785 hydro disc brakes and TRP 140mm rotors and Giant Contact SLR carbon handlebars and stem.

road.cc got the chance to ride this bike over two days in Scotland at the worldwide launch.

Defy Advanced SL 1 £3,499

This is the same frame as the top model but features a Shimano Ultegra mechanical groupset with Shimano RS685 hydraulic disc brakes. Giant P-SLR0 disc wheels with a 30mm deep carbon clincher rim and hubs with DT Swiss internals and Giant Contact SLR finishing kit

Defy Advanced Pro 0 £3,249

The Advanced Pro drops the integrated seatmast in favour or a regular seatpost, with the same d-shaped profiles as the seatmast on the top models. There are the same skinny seatstays too. Otherwise the main change is a switch to a lower grade of carbon fibre, T-700 instead of the more expensive T-800 used in the Advanced SL.

A Shimano Ultegra Di2 groupset with R785 hydro disc brakes and 140mm toros, 11-28 cassette and 50/34 compact chainset, and Giant P-SL0 disc wheels with a carbon fibre rim.

Defy Advanced Pro 1 £2,599

The Advanced Pro 1 also uses the same seatmast-less frame with a Shimano Ultegra mechanical groupset and RS685 hydraulic disc brakes. Wheels are the same Giant P-SL0 Disc with a 30mm carbon rim and 25mm Giant branded tyres.

Defy Advanced Pro 2 £1,899

Again, the same frame but a Shimano 105 groupset with TRP Spyre mechanical disc brakes and 160mm rotors.

Defy Advanced 1 £1,649

The entry-level Advanced range, extending to three bikes, use an ‘Advanced-grade composite’ frame sharing the same tube profiles as the op models, including the super skinny seatstays and d-shaped top tube, with a regular D-Fuse seatpost. EAch of these models uses a regular OverDrive steerer tube with a 1 1/8-inch to 1 1/4-inch taper.

This model is offered with a Shimano Ultegra 11-speed groupset with TRP Spyre mechanical disc brakes and Giant P-R2 Disc wheels with 25mm Giant P-R3 tyres.

Defy Advanced 2 £1,399

Step down the range and this model features a Shimano 105 11-speed groupset with the same TRP Spyre mechanical disc brakes. Wheels are Giant P-R2 Disc with front and rear specific 25mm Giant P-R3 tyres and Giant Contact finishing kit.

Defy Advanced 3 £1,199

The most affordable carbon disc-equipped model in the Defy range is this £1,199 model. It uses a fork with carbon blades and an OverDrive aluminium steerer tube. Groupset is Shimano Tiagra 10-speed with a 50/34 compact chainset and 11-28 cassette. Brakes are TRP Spyre discs with 160mm rotors.

Defy range - £499 to £999 aluminium road bikes

Those are all the disc brake models in Giant’s 2015 Defy range. The entry-level Defy has also been updated offering aluminium frames that share some of the key features of the carbon frames, but using regular caliper rim brakes.

There will be six models priced from £499 to £999. This bike pictured here is that most affordable Defy 5, costing £499 and featuring a ALUXX-grade butted aluminum frame, aluminum fork with alloy OverDrive steerer, Shimano Claris 16-speed groupset and Tektro rim brakes.

I know these aren't touring bikes, but it would be great if there are fixings and just enough clearance for some minimalist mudguards. Perhaps manufacturer specific 'guards.

Know what you mean, some manufacturers are adding really discrete mudguard eyelets or, in the case of the Grade, removable mounts that make them ideal for the winter. There's load of space for a set of Crud RaceGuards however- when the test bike arrives I might just try that

certainly on the Defy Aluminium bikes they have manufacturer specific mudguards and clearances look pretty similar on the carbon ones as well, But I don't know for a fact that the carbon range can have mudguards. I just reckon they do.

I have a 2014 defy3 hapily running a rear rack and 700x28 rear tyre.
The rear mudguard is attached to the rack as the clearance is tight.
as you say this is NOT a touring bike. More a commuter.

I've got a set of SKS Raceblades on my Anyroad 2, work a treat.

Vaguely interesting to note that the bikes with Giant's own carbon rims are running 20/24 spokes.

That's the first time I've seen a spoke count that low on disc wheels, I wonder if they are able to go that low due to the stiffness of the carbon rims?

I'll be very interested to see the weights of those wheelsets, road disc wheelsets seem a bit porky at the moment.

I must admit, they look like a very nice range of bikes.
Almost Aero looking.
Just wondering if the pricing is correct though.
seems to jump a bit.
Defy Advanced Pro 1 with Ultegra £2,599
Defy Advanced Pro 2 with 105 £1,899
Defy Advanced 1 with Ultegra £1,649
Defy Advanced 2 with 105 £1,399
is the Advance pro worth £200 more???

I quite like that Advance 1 with Ultegra.

Could probably bag 10% off for cash and then, (if I could sell my current bike) be left with £500 or so for some HED Ardennes rims with Chris King hubs.

That would be quite a nice sportive bike I would think.

I wonder if the frameset and carbon disc wheels will be available separately? Personally, the bike I really want to see (or frameset) is the a TCR Advanced disc but that may be a while, thanks to the good old UCI.

They will have to be pretty s**t hot. The new Canyon Endurace with Ultegra mechanical comes in £800 cheaper, the Boardman SLS too. I do like my current Defy 1 (aluminium) and the guards were a blessing for those around me on the Prudential 100

So their "pragmatic view" is to ignore thru-axles then.

I have revised my desire for disc brakes to include thru-axles, if they're good enough for MTB why not?

The thing about MTB thru axle standards is they are designed for a different loading, think about how you smash an MTB into berms, ride it over uneven roots etc. The front 'standard' thru-axle size for an MTB is 15mm or 20mm, but that's designed to combat independent leg movement on a suspension fork, it's probably overkill for a road bike fork. A smaller diameter would be lighter, so it's preferable if it will work.

The rear axle MTB standard of 12mm would probably do for front and rear on a road bike, but I don't think anyone makes a 12mm axle front hub.

In an ideal world everyone would just agree a standard at the outset, but of course that's not really in the bike industries best interest.

My MTB (Cotic Soul) uses normal QRs.

I'd like an alu Defy with disc brakes as a winter bike.

Not really. They're for people who ride all year round, in all weathers and are tired of not only wearing out rims, but worrying that their current rims are borderline worn.

It's not all about braking power.
