Cycling Plus Names Propel Advanced Disc “Aero Bike of the Year”
The June issue of Cycling Plus magazine includes its special “Bike of the Year” feature, and editors chose the Propel Advanced Disc for top honors in its Aero Bike category.
The in-depth review details development process of the new Propel Advanced Disc and explains why this composite aero racer stands above the competition: “The new Propel is the result of three years of development, with Giant focusing on having the best weight ratio of any aero bike, and has been designed using Computational Fluid Dynamics (CFD) and wind tunnel work to be adept in adverse wind conditions.”
Cycling Plus editors also praised the performance and integration of Giant components, including the tubeless ready SLR Aero WheelSystem and innovative Contact SLR aero handlebar and Contact SL stem. “Frameset aside, the Propel Disc’s most notable feature is the stem, which hides the shift and cable lines,” they wrote.
And looking at the integrated wheels, they explained the benefits of using a deeper 65mm rear rim and shallower 42mm front: “As wind has little effect on the handling of a rear wheel, it’s deeper and more aero. Up front, the shallower design is less likely to be affected by crosswinds. The tubeless ready rims wear Giant’s Gavia 1 tubeless tires that come up broader than their nominal 25mm size. You can run lower pressures over rough road surfaces without fear of pinch punctures.”
As for its performance on the road, here’s how they summed it up: “When you thread the Propel through corners and push it hard downhill, it imparts wonderful confidence. The ride is as firm as you’d expect from a design so focused on beating the wind, but where it scores highly is in the reduction of the sort of high-frequency vibrations that become wearing over longer rides. The Propel really is a clever bike.”
