Profile Design 39AH Aluminum Extensions Black Profile Design

The Profile Design 39AH Aluminum Extensions is intended to be paired with our pad wadges to convert non-tilting aerobars to have a 10° or 15° of tilt. The name means 39°, aluminium high rise. The extension angle starts at 54° and when adding a 15° pad wedge, balances the angle out to 39° (54° - 15° = 39°). Likewise, when paring with a 10° wedge you get a total of 44° (54° - 10° = 44°). The grip is long enough that it can be shortened for use with the 10° wedge.

The sole purpose of extensions is to provide a comfortable position for the riders hands relative to the armrests. They enhance performance by allowing the rider to relax into their optimal position. Which is why we provide different fit options, so each rider can chase their best performance.

Aero shape like the other A-Series extensions it offers aero shaping in the rise section and a lateral offset for the grip. The 39AH is a 54° bend and when paired with a 15° wedge brings it to 39°. Use the 39AH with one of our pad wedge options and an Ergo+ or Race+ armrest to add tilt and comfort to a non-Profile Design aerobar.

The extensions will fit in any aerobar that is designed for 22.2 mm. So can be used by any rider wishing to improve the comfort of their aerobar grips. They are designed for cables to be routed out the rear of the extensions, so do not have cable exit holes.
