The Blackbird Send Aluminum wheels are designed to eliminate pinch flats and keep the tire sealed no matter what you hit.

The wheelset is made up of a Send 1 rim in the front and a Send 2 rim in the rear. Both rims share a unique hollow box-section beadwall that creates a broad contact point with the tire, which is much stronger and reduces sliced tire sidewalls. The burly Send 2 rear rim includes a pair of ribs directly beneath the bead seat to keep them round after even the hardest hits.

The wheels spin on our 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.
