Profile Design

Century Aerobar

The Profile Design Century Aerobar is a fixed-length clip-on aerobar built for riders who want a stable, repeatable time trial or triathlon position without the complexity of highly adjustable extension systems.

Designed to fit modern road and TT cockpits, the Century clamps to 31.8mm handlebars, and can be adapted to 26.0mm bars with shims—making it a practical aero upgrade for a wide range of bikes and fit setups.

Performance-focused fit details

1. Fixed extension length - Delivers a consistent hand position for steady pacing and reliable fit once dialed
2. 31.8mm clamp compatibility - Direct fit on today’s most common handlebar diameter for a clean, secure installation
3. 26.0mm option with shims - Supports older bars when used with the appropriate shim kit, simplifying upgrades on legacy cockpits
4. Armrest width options - Choose from 82mm, 63mm, or 45mm center-to-center to tune support and control to rider preference
5. Not compatible with riser kits - Best suited to riders targeting a lower, flatter aero position rather than a higher-stack setup
