With the Sonic/Ergo/4525a, Profile Design takes another giant leap forward with aerobar fit range and increased rider comfort. The 400mm long 4525a extensions have an initial section at a 45 degree angle, while the grip portion of the extension is angled at 25 degrees. The extensions additionally have a 7. 5mm lateral shift per side, allowing finer tuning of the grip width. Ergo armrests and pads complete the package, offering both a huge upgrade in fit range as well as increased rider comfort with a supportive cup to the arms. Risers not included.
