The Nimbus 20" Dominator2 rim has a super strong box section and a rigid construction that will build into an ultra strong 20" wheel. This design incorporates a deep inner section which makes it easy to get the tire on and off. The bead seating area contains a retaining lip allowing the tire to be run at low pressure.
This rim fits only true 20" tires (ISO - 406mm)
