The previous generation Giant TCR Advanced SL offered everything you expected from a lightweight, versatile race bike.

However, Giant promises greater rigidity, lower weight and better aerodynamics with this tenth version of the TCR.

Some of these improvements are evident when looking at the bike, while others come from a refinement of the carbon manufacturing techniques used by the brand.

Giant also says that collaboration with Giant-born component brand Cadex contributes to the improvements.

Overall, the new Giant TCR is certainly lighter, maintains impeccable handling and offers an arguably smoother ride quality.

It's a bike that works as an integrated system, as you'd expect, and it's impressive in every way.

However, those who already own the previous TCR may not find the update significant enough to justify the cost, as this model with Shimano Dura-Ace costs €12,299.

Giant's goals are admirable, but when we start from a level already as high as that of the previous generation, these further technical improvements almost seem to want to squeeze the concept of "marginal gains" to the maximum.

Giant has reduced the weight by 75g to an impressive 690g (including integrated seat post and clamp).

It also reduced the surface area of the bike by 2% compared to the previous version, optimizing aerodynamics and making it 4.19 watts more efficient at 40 km/h.

The frame and fork are slightly stiffer (0.53%), but Giant says this translates to an improved stiffness-to-weight ratio of 3.38%.

Again, it's worth pointing out that the previous TCR had no flaws dynamically, and I dare say the same for the previous generation - I've written a comparison between the two.

There's now fully integrated internal cable routing, while changes to the chassis have resulted in a 1mm increase in tire clearance, which can go up to 33mm.

The integrated seat post (ISP) on the SL version is an element that may make resale a little more difficult in the future.

Final thoughts:

The new Giant TCR Advanced SL 0 is a high-level all-round racing bike, light, stiff, aerodynamic but not very comfortable.

Compared to the previous generation, there are improvements, but they are rather marginal and do not justify the change of bicycle.

The high price may discourage those who already own the previous version.

If you're looking for a high-end racing bike and price isn't an issue, the TCR Advanced SL 0 is definitely worth considering.
