Bare carbon and alloy rims for custom wheel builds — sold without hubs or spokes, so you
pick your own. The numbers that matter are depth, internal and external width, ERD and
hole count: internal width sets the tire sizes the rim supports, ERD determines spoke
length, and depth trades aerodynamics against crosswind stability and weight. Check
whether the rim is hookless (tubeless only, with a pressure ceiling) or hooked, and
whether the spoke holes are straight-pull or J-bend before ordering hubs.
