Strong French accent ahead: Micka from DMCX.com reviews The Giant TCR Advanced SL Frame Geometry 2021.

Giant officially presented the Giant TCR Advanced SL 2021 in spring 2020. It is the 9th generation of the frame over a period of 20 years. Giant markets the frame as “Compact Road” frame as the world biggest sports bike manufacturer introduced Top Tube Sloping concept on road bike.

I want to warn you this post is about the technical review as I don’t want people to waste their time here. You will not find actual pictures or glamorous videos road test of the Giant TCR on this page. Only geometry sketches depicting all frame sizes.

Giant is the UCI Pro WorlTour Team CCC sponsor and used the feedbacks team riders lead by Greg Van Avermaet to develop the new frame design and geometry. This means it is a top level frame!

Giant fans will be able to see the TCR Advanced SL 2021 on the big three Grand Tours of 2020 that are the Giro d’Italia, Tour de France and Vuelta a Espana.

Micka from DMCX Reviews The Giant TCR Advanced SL Frame Geometry 2021
Giant had a big task to make the 2021 TCR Advanced SL to make it an even “better” frame than the previous model.

“Better” in the context of the TCR frame stands by a stiffer frame while reducing weight and drag.

Keep in mind Giant is the world biggest manufacturer of sports bicycle as it needs to keep its frame design it reach to general public to keep mass production effective.

That explains why the TCR Advanced SL 2021 frame do not feature full internal routing cables. Thanks to this owner can change the bar and stem more easily than the full integrated and most of the time proprietary parts.

Giant invested in new Robots to assemble “delicately” the 150 Carbon leaves that constitute the frame.

The Taiwanese company started the frame re-design process with new tubes shapes. As a result “Eclipse” shaped frame tubes replace the Teardrop shaped tubes. The so-called “Eclipse” shape is round tube with a flat surface on the rear facing side.

The Eclipse shape optimizes aerodynamics and increase structural strength on the front end of the frame. The front triangle looks beefier than previous TCR version while reducing weight.

The oversized headset branded as “Overdrive 2” which is a 1 1/2” lower, 1 1/4” upper is participating in the stiffness on the frame.

The rear triangle features a new designed derailleur hanger and Asymmetric chainstays.
The Bottom Bracket is the massive 86mm wide Press-Fit type which contributes to the frame stiffness.

The particularity of the TRC Advanced SL is that is feature an Integrated Seatpost. This save approximately 45g compared to a separated carbon seatpost. Beside the saved grams it does also improve frame stiffness and aerodynamic.

To support the frame stiffness a new fork has been developed too and is also looking sturdier than previous model. The fork arms have leaving plenty of space for air to flow between the the arms and the spokes. Giant calls it a Symmetric design fork and this decrease Air drag as a result.

The fork features taper steerer tube, internal cable routing, flat-mount disc brake type and 100x10mm thru axle. It is the same on all TCR Advanced SL Disc frame size.

The Geometry
The main differences in the 2021 Giant TCR Advanced SL frame geometry is a lower Bottom Bracket (BB).

The frame head tube, top tube and seat tubes dimensions have also been revised on all sizes.

It is good to see Giant lowering the BB height of its 2021 Giant TCR frame geometry. This is helping to lower the center of gravity and decrease drag. It is not as low as other racing frames Giant is taking a first step toward optimization.

The head tube and seat tube angles feature an open angle reflecting a nibble handling and short wheelbase. That might comes as an handicap at the end of a long ride when the rider feels tired and reactivity not as sharp as at the start and on tough road condition.

The same fork with 45mm rake and 32mm tire clearance complements all Giant TCR Advanced SL frame sizes .

Giant does recommend the XS size for riders from 157cm to 169cm tall (5’2″ to 5’7″) The Top Tube is 520mm length. 
The S size for riders between 165cm and 175cm (5’5″ to 5’9″). The frame feature a 535mm Top Tube length.
The M size is recommended for rider from 171cm to 181cm (5’7″ to 5’11”)
The ML size for people from 177cm to 187cm (5’10 to 6’2″). It features a 565mm Top tube length.
The L size for 183cm to 193cm tall riders (6’0 to 6’4″)
The biggest available XL size is dedicated for riders 189cm to 199cm (6’2″ to 6’6″).
