Giant Defy Adv Pro 1 2018 Road Bike


Hi. Greg Griffiths here from Ivanhoe
Cycles. This is the 2018 Giant Defy Advanced Pro 1. This is – as the name
implies – a Giant Defy, which means that it has a slightly longer wheelbase than the
strictly racing models. So it’s an endurance road bike. A little bit longer in the
wheelbase, a little bit more relaxed in the angles, a little bit taller in the
front so the rider sits up a little bit higher and has a little bit more
comfortable ride than on a serious racing bike. So it’s an endurance road
bike, designed and made for the recreational rider who may never pin a
number on a going race, but who does want to ride longer distances and ride
regularly. So it’s quite a comfy ride and that’s
also enhanced by the DeFuse seatpost which, because of its shape and design,
there’s a little bit of flex backwards and forwards in the seatpost when
you’re on the rougher road. So it is quite a comfy ride. Another really nice
feature about this particular bike is the fact that it has tubeless
tyres and they’re attached to carbon fibre or composite rims. So it’s a very
light wheel setup because there is, first of all, the light weight of the rim
structure and the fact there’s no tube inside. So it means they can be ridden at
a slightly lower pressure if you wish, so that that rider comfort can be
further enhanced by having slightly less pressure in the tyre. So it’s a really
nice feature. If you do happen to get a puncture, you can either fill the tyre
with sealant or you can just remove the tubeless valve from the rim, put in a
regular tube and and just repair it to get yourself home. So it’s a really nice
wheel setup. Another really good feature on this bike and for a road bike is the
fact that it has hydraulic disc brakes and, in this case, they have a special
disc rotor that has cooling vents so to help dissipate the heat so the braking
even if you’re on a quite a long descent down a mountain with a lot of heavy
braking, the disc doesn’t overheat and the braking stays consistent. Also with
this bike, it has – rather than the regular dropouts where the fork will fall out of –
the wheel will fall out of the fork – on the front and the rear, it has what’s
called a thru-axle. So removal of the wheel is
slightly different. So I’ll just demonstrate that to you. To remove the wheel, just
undo the lever on the left side of the bike, pull the axle out and the wheel
falls out. That’s crazy simple and really easy to
do and the refitting is just a matter of guiding the disc rotor between the brake
pads, reinstall the axle and do it back up. So wheel removal and wheel re-fitment is
super easy. The reason they do this, it means that the front end can be quite a bit
stiffer. The fact that the wheel is actually bolted in, rather than with a quick
release lever. So it’s a good setup. Wheel removal, as you can see there, was
really quick for the professional riders racing, it’s perhaps a fraction slower
than with regular quick-release, but there’s not too many of us that are
professional racers, so that’s not really a concern. The same setup with the back,
just wheel removal is as easy as unscrewing the lever, pull it – pull the axle
out and the wheel falls out of out of the bike. Because this is an
Advanced Pro 1, as I have already mentioned, it has the carbon rims, a
slightly better quality handlebar and stem than the regular Defys and it also
has an Ultegra or Shimano Ultegra groupset. This is the
latest model Ultegra. Quite distinct with the wider crank, which means
it’s just a little bit stiffer than the previous models with the slimmer crank.
So no power – or rider power is lost in the cranks flexing at all.
They have Press Fit bottom bracket bearings in the frame, so the assembly is
quite robust and yet amazingly simple and very stiff. So power transfer being
near the optimum area of the bike is around here, so stiff cranks, stiff bottom
bracket means that all of your power goes to the road. So it’s quite a good
performing bike, even though it’s not a strictly a race bike. As I mentioned, it has
Shimano Ultegra components and that includes the crankset, the front
derailleur, the rear derailleur, the cassette and the chain. In this case, it
has a compact crankset, which is a 50-tooth large chainring and a 34-tooth inner
chainring, so that’s what’s called a “compact crank” compared to the racing
bikes where it will be 53 and 39. So slightly lower, aimed at helping the
recreational rider in most situations and particularly climbing. The gearing is
lower to get you up the hills easier and that’s aided by the wide-range rear
cassette, whereas a regular road bike might have an 11 to 25 or 11 to 27 – if
you’re lucky – cassette, this one goes from 11 all the way up to 34 teeth. So the
gearing on this bike is super low. 34 tooth chainring, 34 at the back –
obviously it’s one revolution is one turn of the – one revolution of the pedals is one turn
of the wheel, so it’s a very low gear and it means that anybody could climb up
almost any hill. You know, there are a lot of people who ride the Three Peaks or those type
of rides, the backside of Falls Creek is a major challenge for many people – this
gearing would certainly get you up there far easier than most bikes and with the
disc brakes and the stability of a bike like this, coming down the other side is
also done with ease. So it’s a great bike, really nice features. This gearing
change to this extraordinary range there will be a big bonus. So anyone buying a
bike in 2018 who wants to ride in a variety of conditions or terrains,
something like this would be ideal. Comes in a range of sizes. This particular
bike is a small, but there’s from extra small to extra large – so from people 5
foot 2 or 3, up to 6 foot 4 or 5 – there’s a bike to suit everyone. So really nice
bike, very comfy, lightweight, great brakes, got great gears and a comfortable ride.
So, if you’re the market for a road bike, you couldn’t go past this unless you’re
strictly racing or it doesn’t meet your budget either it’s too cheap or
too expensive. So but a great bike all-around. Thanks very much.
