The 45AR extension offers comprehensive yet simple adjustment, ideally suited to riders wishing to add aerobars to their road, gravel or packing bike.
This extension can be used for draft legal triathlon once shortened to meet the ITU rules.
Profile Design has a long history with shorty/DL style bars. This is our latest offering and the most adjustable yet. We wanted to create a bar that would be an easy and comfortable addition to road, gravel and packing bikes.
