Giant's 2027 Propel and Liv EnviLiv arrive in Australia lighter and faster

Giant's Propel has been the brand's aero road bike since 2012, and the fourth generation has landed in Australian stores with a full rebuild rather than a refresh. The 2027 range, alongside the women's specific Liv EnviLiv that shares the same platform, is now available to order through Giant dealers including Giant Lygon St in Melbourne, with the entry level Propel Advanced 1 listed at $6,799.

Lighter, and still slippery

Giant says the flagship Propel Advanced SL 0 AXS build weighs 6.56kg, a claimed 355g drop on the previous generation, at a time when most aero bikes have been getting heavier rather than lighter to chase marginal gains. The company claims an 18.44 watt reduction in total resistance compared with the outgoing Propel, a figure that folds in the new Cadex Max 50 wheelsystem and Cadex Aero tyres rather than the frame alone. At 40km/h that works out to roughly a minute saved over a 40km ride, according to Giant's own numbers.

More room for real roads

The bigger change for everyday buyers is tyre clearance, now up to 32mm, which brings the Propel into line with the wider tyres most Australian riders already run on rough chip seal and pothole prone city streets. The frame is also Universal Derailleur Hanger compatible, and gets a new integrated handlebar and stem system.

What it means for buyers

A sub $7,000 entry point for a genuine aero platform puts the new Propel and EnviLiv within reach of serious club riders, not just the pro peloton, and the wider tyre clearance makes it a more realistic daily bike than the last generation.
