The Blackbird SendAluminum rims are designed to eliminate pinch flats and keep the tire sealed no matter what you hit. Ibis Cycles offer two versions. The Send 1 and 2 rim share a unique hollow box-section beadwall that creates a broad contact point with the tire, which is much stronger and doesn't slice tire sidewalls. The Burlier version, the Send II, adds a pair of ribs directly beneath the bead seat to keep them round after even the hardest hits.

The wheels spin on Ibis Cycles house designed hubs, which feature four pawls and 36 teeth for 10° of ultra reliable engagement. Tubeless ready out of the box with tape and valves pre-installed. Built with Sapim spokes and nipples so that spares are easy to source.
