Federal Aero XL Rim supplier_54521986679110 What set the Proton apartThe Federal Aero XL rim is made from the same AL6066 Aluminium as the Stance XL rim and is also 40mm wide. Federal decided to utilise an oval design to create their strongest rim to date. Due to the additional depth of the oval shape it also makes it more resistant to flat spots from heavy landings than a traditional rim. ###section### Product Specs WHEEL SIZE: 20" SEAM: Welded ERD: TBC HEIGHT: 22mm WIDTH: 40mm SPOKE HOLES: 36h WEIGHT: 575g
