The Rollcage uses standard 6061-T6 aluminum instead of the Ribcage’s proprietary grade, and the Rollcage also goes without the Ribcage’s outermost reinforcing ribs for the spoke nipples – a feature that requires greater precision when it comes to drilling the spoke holes.
The Rollcage makes use of the Ribcage’s proven cross-lacing for improved durability and stronger wheel builds, and also incorporates a similar cross-sectional design that has been narrowed down to 34mm’s. Additionally, this section-shape utilizes thick 2.1mm sidewalls for impact resistance. You’ll be able to tell the Rollcage “by eye” because it has a groove that runs along the center of the rim.
