If the Ribcage is too rich for your blood, the Rollcage is its more affordable, lighter sibling. Using the same proven shape and cross-over lacing to create a really strong wheel, but industry standard 6061-T6 alloy and no ribs drops the priceconsiderably.
The Rollcage has the same super tough sidewall and bead profile of the Ribcage but it's 10% lighter. You will recognize the rims by their outer shape, but the Rollcage is actually 2mm narrower and easily identified by the groove in the middle of the innerwall.
