Notre avis
The Deda Parabolica 1 K extension is the most versatile version in the Parabolica range. The letter K indicates the inclusion of a riser to better adjust the height of the extensions.
Aurélien L.
Cycling in all its forms
This version of the Deda Parabolica 1 K extension fits 31.8mm diameter handlebars to provide a versatile and comfortable aerodynamic position by adjusting the height relative to the handlebars.
Made from 6061 aluminium, it is lightweight, weighing 540g including all the stem extensions. It will easily find its place whether on a late-season time trial bike or for daily training. Installation is extremely quick and easy. This is the shape to go for to enjoy time trials.
It is also possible to fit shifters at the ends of the handlebars, whether mechanical or electronic.
