GiantPropel Advanced SL
The fourth-generation Propel Advanced SL is Giant's flagship aero road bike, raced by Team Jayco AlUla. Giant rebuilt the Advanced SL-grade frame around a one-piece front triangle, added a one-piece bar and stem with narrower drops and hoods, opened tyre clearance to 32 mm and kept the integrated seatpost. Giant claims 18.4 W less total resistance at 40 km/h than the previous Propel Advanced SL. It is sold as SRAM Red and Dura-Ace Di2 complete bikes and as a frameset.

Our verdict
Overall
out of 100, average of 6 categories
Giant's lightest Propel yet pairs an 800 g frame with a one-piece cockpit and published tunnel data, making it one of the most complete aero race bikes. You trade adjustability: the seatpost is integrated, the cockpit is proprietary, and there is one stem length per size.

Good to know
Design
The front triangle is now moulded in one piece around a single bladder instead of the previous generation's three, which Giant says saves weight without losing stiffness.
SourceDesign
Giant says the frame is 45 g lighter than before; with the one-piece cockpit, new wheels, tyres and lighter parts the SL 0 complete bike saves 355 g.
SourceDesign
Giant claims up to 25% more vertical compliance at the rear from the reworked seat tube, chainstays and seatpost, and 12.8% more front-end compliance from the new cockpit.
SourceDesign
Giant measured 2.4% more pedalling stiffness and 3.3% more torsional stiffness than the previous Propel Advanced SL frame.
SourceAerodynamics
In Giant's test of a size M bike, total resistance fell from 267.76 W to 249.32 W: linear aero drag 234.9 to 222.48 W, wheel rotating drag 5.46 to 5.04 W and tyre rolling resistance 27.4 to 21.8 W. The new bike ran 28 mm CADEX Aero tyres and Max 50 wheels against 25 mm tyres and Ultra 50 wheels.
SourceFit
The one-piece bar is narrower than the old two-piece setup: Giant tested a 400 mm drop and 370 mm hood width on size M against the previous 420 mm straight bar.
SourceRacing
Mauro Schmid won stage 13 of the 2026 Tour de France on the new Propel Advanced SL with Team Jayco AlUla.
SourceHistory
Giant launched the fourth-generation Propel in March 2026 in three series: Advanced SL, Advanced Pro and Advanced.
SourceVersions
The Advanced Pro and Advanced frames weigh 863 g in Giant's comparison and use a telescoping aero seatpost instead of the integrated one.
