Time trial2025Trinity Advanced SL (successor to the rim-brake Trinity Advanced Pro) ↗Disc brakesUCI legal

The time-trial kit of Giant's disc-brake Trinity Advanced SL. It uses the same Advanced SL-grade carbon frame and fork as the triathlon version, but ships with a down-tube bottle and cage instead of the hydration reservoir and bento box, and its arm pads sit about 47 mm lower and 16 mm further forward. It is sold as a frameset with the AeroDrive base bar, integrated stem, Sync armrests and composite seatpost.

Our verdict

No overall score: there's no complete-bike price to rate

The UCI-ready version of Giant's disc-brake Trinity, with the same light Advanced SL frame, wide armrest adjustment and four-position seatpost but only a down-tube bottle for hydration. It suits time triallists who want a lower, longer pad position; the press-fit bottom bracket and Giant's own cockpit are the trade-offs.

Good to know

  • Design

    Giant says moving to Advanced SL-grade carbon, with lighter paint, seatpost and bars, saves 558 g over the previous Trinity Advanced Pro frameset without losing stiffness.

    Source

  • Fit

    Giant lists arm pad stack of 582-662 mm (XS) to 643-723 mm (L) and reach of 339-414 mm to 395-470 mm for the TT kit; the frame geometry, 400 mm base bar width and crank lengths match the triathlon version.

    Source

  • History

    Giant announced the Trinity Advanced SL in January 2025 as the disc-brake replacement for the rim-brake Trinity Advanced Pro.

    Source

  • Versions

    Giant sells the Trinity Advanced SL frameset as a triathlon kit and a time-trial kit at the same US price. The TT kit swaps the hydration kit and bento box for a down-tube bottle and cage, and its listed arm pad stack and reach differ from the triathlon kit's.
