The original took the idea of compact sloping frame geometry from mountain biking and adapted it for the road (TCR stands for Total Compact Road). The TCR has been a staple in Giant’s range since 1998, with the first iteration coming from the mind of British bike design legend Mike Burrows (of Chris Boardman’s Lotus pursuit bike fame) back in 1995.

TCR Advanced SL Disc only compatible with electronic groupsets.

Rim brake frames available at all three levels.

Advanced Pro Disc and Advanced Disc frames also updated.

Tyre clearance increased to 32mm on disc frames (28mm for rim brake frames).

34 seconds faster than previous bike over a distance of 40km at 200 watts.

‘Truncated ellipse’ tube profiles to improve aerodynamics.

Best-in-class stiffness-to-weight ratio, according to Giant.

765g claimed weight for TCR Advanced SL Disc frame.

Rim brake models are available at all three frame levels. Giant has also updated the second-tier Advanced Pro Disc and third-tier Advanced Disc frames. The aerodynamic difference between the TCR and the Tarmac and R5 is also extremely small. The TCR Advanced SL Disc is said to out-perform all three rivals on most counts (the Emonda is lighter), though this is based on Giant’s own testing and, of course, against a very select number of bikes. That’s the blend of attributes these all-round race bikes are now looking to achieve. Giant’s press material for the new TCR contains comparisons with three leading rivals – the Specialized S-Works Tarmac Disc, Trek Emonda SLR Disc and Cervélo R5 Disc – for weight, stiffness-to-weight and aerodynamics. Stiffness-to-weight ratio has also been improved, according to Giant, while a smattering of aero touches have made the new frame faster in the wind tunnel.

The 2021 TCR Advanced SL Disc frame comes with a headline claimed weight of 765g.
