Kalin Aluminium 500mm Seatpost for folding bicycles

This is an exact replacement seatpost for our Downtube bicycles. 500 mm long gives plenty of length for taller riders. Standard interface accepts any saddle. Please select 27.2 mm or 30.4 mm diameter. Most models from 2005-2007 used 27.2 mm, while newer models mostly use 30.4 mm, so please check before you order.
