Giant Propel Advanced SL review: Showing its age a little but can still mix it with the best

Dec 2024 · Will Jones

Launched in 2022, the Giant Propel is an aero bike with softer edges that makes it an excellent all-rounder

Highs
  • Genuine all-round capability

  • Comfortable enough for all-day riding

  • Separate bars mean easier and cheaper fit adjustment

  • Stable on high-speed descents

Lows
  • Narrow tyres as stock

  • Better with deeper wheels

  • Not as aero or as cheap as the Factor Ostro VAM

  • Integrated seatpost is annoying to live with
