The V4+ Carbon introduces a new extension paired with the new L2 bracket. The V4+ extension is a variation of the T4+ extension bend featuring a higher rise Ski-bend to compensate for the lower mounting position of the extensions. The clamp design places the extension below the basebar with a stack height of 2.25cm below the T series aerobars. Combining the L2 bracket and F40tt armrest offers small incremental adjustments producing our best ever reach and width range. Extension Length 366mm Extension Height 84mm Extension Angle 10 Clamp Diameter 31.8mm (26.0 w/Shims) Color Black
