Who is it for

This bar is perfect for riders who wish to achieve lower positions than are possible with standard aerobar designs. Unlike other low stack bars it allows fine-tuning of the stack height so the rider is not limited to only one arm pad height. With the Race armrests fitted it is tailored towards riders who intend to be low and narrow to punch the smallest possible hole through the wind.
