0:00 so this is just a quick video looking at
0:02 the giant defy and the giant TCR and
0:07 differences in their geometry and how
0:09 that would affect the handling of the
0:10 bike and the comfort so we're looking at
0:14 the Defy 2017 designed for endurance and
0:18 sportives and TCR more of a race bike
0:22 in fact Tom Dumoulin won the Giro
0:27 d'Italia on it two days ago three days
0:31 ago two days ago so what I've done is
0:35 basically lined up the front wheel as
0:42 best I can on each image to the center
0:50 of the axle there okay
0:57 and using the measurements from the
0:59 giant website as compared to the
1:04 different frames so the first thing I
1:08 looked at was trail and the TCR has 5%
1:18 less trail than the defy which is going
1:23 to equate to slightly quicker steering
1:29 the less the trail the faster the
1:31 steering that was on a medium-sized
1:34 frame next thing I looked at was the
1:41 wheelbase and the defy is 2% longer
1:51 than the TCR which means that it's going
1:56 to be more stable at higher speeds
2:00 downhill what-have-you if i zoom in on
2:06 the back there you can see the Defy's
2:12 quite a bit longer, the TCR is going to
2:17 be a bit more nimble but a bit more
2:23 jittery at high speed ok
2:30 next I looked at stack height and reach
2:35 and as you'd imagine that defy has got a
2:45 higher stack and a shorter reach so 4%
2:49 higher stack and a 1.5%
2:52 shorter reach we zoom in there you can
3:02 see there that basically that the ride
3:07 on the defy is going to be more
3:09 comfortable on your back and your
3:11 shoulders and your neck is going to be
3:13 sitting slightly higher up or more
3:15 upright however you would be more aero
3:21 on the TCR there we go that was my quick
3:28 look at the differences between the TCR
3:31 and the defy frame geometry
