- Giant's oversized head tube and down tube make for a stiff front end. Like the Defy and Advanced SL, the TCR Advanced now has internal cable routing. It is also Di2 ready (note the small plug underneath the top tube). Photo: Nick Legan
- Giant's OverDrive 2 uses a 1.25-1.5" steerer tube. This means that normal 1.125" stems won't fit but also makes for a stiffer front end and (Giant claims) more precise steering. The 2012 TCR Advanced did handle very well. Photo: Nick Legan
- With all the features of its more expensive brother, the Advanced SL, the TCR Advanced is a bit more practical with its telescoping seat post. I felt it was a bit more compliant than the spendier bike without any loss in efficiency. Photo: Nick Legan

- The TCR Advanced W frames have women's specific geometry and tube sets. This model will cost around $3,700 and thankfully, isn't in pink. Photo: Nick Legan
- The Defy Advanced SL frame is actually lighter than the TCR Advanced SL. It'll be spec'd with a compact crank and retail for $7,000. This could be a real winner in the endurance category. Photo: Nick Legan
- Giant's Defy is ready to do battle in the endurance bicycle category. I would recommend it for those seeking an endurance bike with subtler differences from a race bike. The head tube is not as tall as a Specialized Roubaix or many other endurance bikes. For some (like me) this is a very good thing! Photo: Nick Legan
- The down tube on the Defy is still quite large, but the shaping isn't nearly as box-like as the TCR line. Photo: Nick Legan
- Giant has made this editor very happy with its new seatpost head. The polished seat rail clamps can be turned forward to act as a -5mm setback seat post. As this one is installed, it gives 20mm of setback. Photo: Nick Legan
- Giant uses its PowerCore on the Defy. The Pressfit BB86 bottom bracket now features full carbon cups. Photo: Nick Legan
- The Defy's geometry is quite different from the TCR line but the frames appear very similar. One small difference is where the seatstays meet the seat tube. The junction is lower on the Defy. Photo: Nick Legan
- Like the TCR line, the Defy receives the new OverDrive 2 head tube and fork and internal cable routing. Photo: Nick Legan
- 2012 frame weight for a medium frame is down to 820 grams. In 2011 the same size frame weighed 968 grams. Fork weight is simliar to last year at 330 grams. Photo: Nick Legan
- For 2012, the TCR Advanced SL gets carbon fiber dropouts and the derailleur hanger is not mounted on the inside of the dropout. To help avoid rattles, the internal cable routing doesn't feature a liner. Photo: Nick Legan
- Giant now has a seatpost head that offers both -5mm and 20mm of saddle setback. The silver pieces flip around for the change. This one is set up with -5mm of offset. Photo: Nick Legan
- Like Trek's Duo Trap, Giant now has an ANT+ speed and cadence transmitter. Photo: Nick Legan
- Giant managed to shave a few more grams off its PowerCore bottom bracket for 2012. The system now has full-carbon cups. In this photo you can also see more of the Di2 integration: the wiring plug on the back of the seat tube and the battery mount under the non-drive chainstay. Photo: Nick Legan
- Giant's handlebars and stems both work well. The stems are necessary for the new OverDrive 2 1.25-1.5" steerer (but FSA, Ritchey and Syntace also offer stems in 1.25" diameter). Photo: Nick Legan
- Citing less weight, better aerodynamics and better foul-weather protection, Giant has moved to internally routed cables for 2012. I'm still not convinced that it's a functional improvement, but the aesthetic is nice. Photo: Nick Legan
- It's no surprise that Giant's new frames are Di2 ready (the small plug under the top tube). The Rabobank team is Shimano sponsored afterall, but most consumers demand clean Di2 routing as well. Photo: Nick Legan
MALLORCA, Spain (VN) — Giant hasn’t gone and completely redesigned its road line. Model names are the same as before (TCR and Defy for the boys, TCR W and Avail for the ladies). But with subtle changes in materials and design the world’s largest bicycle manufacturer has improved its entire range.
Giant has introduced some new technologies that will be included on most Giant models (some even in the mountain bike line): OverDrive 2, PowerCore and RideSense. Giant also showed off its new internal cable routing and a new seatpost head. Before we get to the bikes, a little bit about Giant’s 2012 innovations:
OverDrive 2 uses a 1.25-1.5 inch tapered steerer. This, of course, means that 1.125” (1 1/8”) stems won’t fit on the new system. Several manufacturers are already on board though: Syntace has long made stems that fit the larger steerer and provide a spacer for 1.125” use. Ritchey and FSA (which we saw branded as PRO on Rabobank team bikes at the Dauphine and Tour of Switzerland) also make stems for the larger steerer tube. And of course, Giant also produces stems for the new standard.
The idea isn’t a new one. But it is the first time a manufacturer of this size has committed so thoroughly to it. Cannondale and others experimented with larger steerers in the past, but advances in carbon have made it a more viable option. Specialized experimented with the size in its mountain bikes a couple years ago, but dropped it. Canyon currently uses it on its Ultimate CF SLX Evo frameset.
One unique aspect of Giant’s OverDrive 2 is that it fits inside the same head tube they’ve made for years. Engineers simply increased the internal diameter of the upper bearing to fit the larger steerer. Owners of older Giants can purchase the new fork, upper headset bearing and a suitable stem and upgrade their bike with OverDrive 2.
PowerCore is actually nothing new. It was introduced in 2009. It uses the Pressfit BB86 standard but for 2012 the bearing cups are now full composite (not aluminum). This produced a 15-gram weight savings over previous models.
RideSense is a chainstay-mounted wireless, integrated sensor that transmits speed and cadence using ANT+ technology. Much like Bontrager’s Duo-Trap, the unit bolts into the non-drive side chainstay. RideSense doesn’t follow the frame’s lines as well as Trek’s, but it does work well.
Both the TCR and Defy lines now have internally-routed cables. Now I’m not usually a fan of internal cables as I see it answering a question no one (or at least very few) is asking. Giant pointed out that it saves a bit of weight, cleans up a frame aerodynamically and keeps the cables out of the elements. Fair enough, but they’re still a pain to maintain and install.
While Giant’s frames come with temporary plastic routing guides to help with the initial install, there isn’t a permanent liner inside frames. Because of this, shops would be wise to keep the temporary lines for future cable changes. Giant reasoned that permanent liners will often allow a cable to rattle inside the frame and Giant may have made a good decision. The cables certainly never rattled on any of the bikes I rode (they also don’t rattle on my personal externally-routed bicycles).
Giant’s new seatpost head is one item that I personally love. Finally a manufacturer has realized that consumers have different saddle setback needs. I personally need a zero-setback seat post on almost every bike I ride. With most other aero or integrated seat post designs, the consumer is stuck with setback.
Giant’s has two versions of the head, one for integrated clamps and a slightly different version for aero seatpost models. Both work well and offer either 25mm or -5mm of setback depending on set up. It’s a genuinely clever solution to a problem I’ve moaned about for years. Chapeau!Pages: 1 2
