Propel Advanced 1

The Giant Propel Advanced 1 (2027) is built for riders who want aerodynamic speed, responsive handling, and modern road-race performance without sacrificing everyday ride comfort. Giant’s redesigned Propel Advanced combines an Advanced-grade composite frameset with AeroSystem Shaping technology and integrated components to create a fast, efficient, and highly capable aero road bike.

The Propel Advanced is designed around three key performance goals: instant speed, sustained speed, and top-end speed. Its aerodynamic frame, integrated Contact SL Aero handlebar and stem, 50mm carbon WheelSystem, and aero tires work together to reduce drag and rolling resistance when you're pushing the pace.

For 2027, the Propel Advanced features increased tire clearance for tires up to 32mm, giving riders the option to run higher-volume tires for additional comfort and control while maintaining the bike's aerodynamic performance. The Vector composite seatpost also adds compliance to help smooth road vibrations on longer rides and high-speed training sessions.

The Propel Advanced 1 comes equipped with a complete Shimano 105 Di2 12-speed electronic drivetrain, Shimano 105 hydraulic disc brakes, and Giant SLR 2 50 Carbon Disc WheelSystem wheels. It is a strong choice for road racers, fast group riders, cyclists looking for an aerodynamic race bike, and riders who want high-level performance in a versatile package.

Key Features

AeroSystem Shaping – Aerodynamically optimized frame tubing developed using CFD modeling and wind-tunnel testing to reduce drag across a range of riding conditions.

Advanced-Grade Composite Frameset – High-performance carbon construction designed to provide an excellent stiffness-to-weight ratio and responsive power transfer.

Integrated Aero Cockpit – Giant Contact SL Aero integrated handlebar and stem with internal cable routing for a clean aerodynamic profile.

50mm Carbon WheelSystem – Giant SLR 2 50 Carbon Disc WheelSystem combines 50mm-deep composite rims with an aerodynamic profile designed for speed and efficiency.

Shimano 105 Di2 12-Speed – Electronic shifting provides precise, fast, and consistent gear changes with the wide-range performance needed for racing and everyday riding.

Hydraulic Disc Brakes – Shimano 105 Di2 hydraulic disc brakes provide confident braking and control in a variety of conditions.

Vector Composite Seatpost – Aero-shaped composite seatpost designed to balance aerodynamic performance, low weight, and increased compliance.

Up to 32mm Tire Clearance – Increased clearance allows the use of higher-volume tires for improved comfort, control, and efficiency.

Internal Cable Routing – Frame, fork, handlebar, and stem routing keeps cables protected and improves the bike's aerodynamic profile.
