Across the 21-inch profile you'll find the Cairo, Milan, Vegas, and Verona designs, each cast as a one-piece structure with a deep-concave, multi-spoke face.

Why a 21-inch XO fitment matters
At 21 inches, the wheel sits in the sweet spot between the everyday usability of a 20 and the show-stopping scale of a 22. The diameter lets a tall, premium platform run a low-profile tire without overwhelming the fender, and XO's monoblock construction keeps the spoke face structurally simple and visually clean. If you want to compare the rest of the range, the full XO lineup spans several diameters, and you can step the same designs down to 20-inch XO wheels or 19-inch XO wheels, or scale up to 22-inch XO wheels.
Which 21-inch models & finishes
Four designs carry a 21-inch option. The Cairo comes in Bronze w/ Brushed Bronze Face and Carbon Graphite. The Milan offers Candy Red, Matte Black, Matte Black E, and Matte Silver w/ Brushed Face. The Vegas is available in Gunmetal w/ Brushed Gunmetal Face and Silver w/ Brushed Silver Face. The Verona is the broadest, with Candy Red, Matte Black, Matte Gunmetal, Matte Gunmetal E, Matte Silver, Matte Silver E, and Silver w/ Brushed Face.
To shop by color across all sizes, browse black XO wheels, silver XO wheels, gray XO wheels, bronze XO wheels, red XO wheels, or the brushed XO wheels if a machined face is the look you're after.
21-inch fitment coverage
The 21-inch designs are drilled in the five-lug patterns common to European and performance platforms. Cairo covers 5x108, 5x112, 5x114.3, and 5x120. Milan adds 5x115, 5x127, and 5x130 on top of those. Vegas runs 5x112, 5x114.3, and 5x120, while Verona is the widest-ranging with 5X110, 5x112, 5x114.3, 5x115, 5x120, 5x120.65, 5x127, 5x130, and a blank option. Match your hub by pattern: XO 5x112 suits many Audi and BMW applications, XO 5x114.3 covers a wide span of Japanese and domestic platforms, XO 5x120 fits BMW and several luxury models, XO 5x108 works for many European cars, XO 5x115, XO 5x130, and the unusual XO 5x120.65 round out the offering.
How to choose
Start with your bolt pattern, then confirm the diameter clears your brakes and matches your tire plan. For a stealth build, the Matte Black Milan or Verona keeps things understated; for contrast and depth, the brushed and milled faces on Vegas and Cairo catch light without going loud. Reference pricing on related fitments to set expectations: the XO Cairo 5x112 in Carbon Graphite, the XO Milan 5x108 in Matte Black, the XO Vegas 5x114.3 in Gunmetal w/ Brushed Gunmetal Face, and the XO Verona blank in Matte Silver all share the design language you'll see at 21 inches.
