Description

Simone Barraco's signature rim, built for his mix of technical and burly street riding. Shadow used a proprietary high strength aluminium alloy and a specially designed internal spoke seat to make this their strongest rim yet, so it takes the abuse whether you run high pressure or super low pressure in the streets.

It is a 20 inch, 36 hole rim with offset spoke drilling and a dual chamber double wall design, 36mm wide and 18.5mm tall. The extruded, heat treated 6061-T6 alloy shell has a welded seam. ERD is 388mm and the weight is 17.4 oz.
