Riviera rv136 Alloy Wheels. Available in various widths, sizes and fitment types. A modern interpretation of the classic five-spoke, the RV136 features a “Y-Stem’ configuration that filters to a ten-spoke, mesh design. The multi-stem profile offers improved brake cooling and a more impactful overview of the braking system. Finished in gloss black, the RV136 is at home on the race track as it is on track.
