Ibis Blackbird Send I 29" Rim

Intro­duc­ing the Send rims from Black­bird, a new com­po­nent brand for Ibis Cycles. When they set out to improve their indus­try-lead­ing S35 rims, their mis­sion was sim­ple; elim­i­nate pinch flats and keep the tire sealed no mat­ter what you hit.

Pinch flats occur when you hit your wheel hard enough to ​“pinch” the tire between your rim and that rock or root that you didn’t see com­ing. Hit hard enough and the edge of your rim, the bead wall, will slice clean through that brand-new tire you just installed.

To elim­i­nate pinch flats, Ibis designed their bead walls with a hol­low box-sec­tion pro­file to remove the sharp edges and cre­ate a broad con­tact point with the tire. This box-sec­tion results in a stronger bead wall that doesn’t slice tire side­walls and it doesn’t add any addi­tion­al weight. Ibis' unique bead wall is used on both the Send 1 and Send 2 rims, but the Send 2 gets extra reinforcement.

Which rim do you need?

Are you looking for a lightweight aluminum rim with good strength? You’ll want the Send I. Need something a bit burlier? Choose the Send II that has extra reinforcement. Ibis' Enduro World Series Team has been riding with the Send I in the front and Send II in the rear with great results.
