Blackbird Send Wheelset
Blackbird Send Wheelset, Intro duc ing the Send wheels from Black bird, a new com po nent brand for Ibis Cycles. When Ibis set out to improve their indus try-lead ing Ibis alu minum S35 rims, the mis sion was sim ple; elim i nate pinch flats and keep the tire sealed no mat ter 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 com ing. Hit hard enough, and the edge of your rim, the bead wall, will slice clean through that brand-new tire you just installed.To elim i nate pinch flats they designed the bead walls with a hol low box-sec tion pro file to remove the sharp edges and cre ate a broad con tact point with the tire. This box-sec tion results in a stronger bead wall that doesn&';t slice tire side walls, and it doesn&';t add any addi tion al weight. The unique bead wall is used on both the Send 1 and Send 2 rims, but the Send 2 gets a lit tle some thing extra.If you ride hard, you know you&';re going to dent your alu minum rims even tu al ly, and it&';s your rear wheel that takes the brunt of the dam age. You can bend back a bead wall but dent your bead seat (where your tire seals), and you&';ll be walk ing back to the trail head. You can&';t bend the bead seat back, which means you can&';t run your tires tube less.To rein force the bead seat on the Send 2 rims, Ibis added a pair of ribs direct ly beneath the bead seat. The Send 2 gains 45g per rim because of this rein force ment, but it is a small penal ty com pared to the weight of the insert you need to pro tect flim si er rims.Are you look ing for a light weight alu minum rim with good strength? You&';ll want the Send 1. Need some thing a bit burli er? Choose our Send 2. The Ibis Enduro World Series Team has been test ing the Send 1 on the front and a Send 2 in the rear for the last two years. Four EWS rac ers, sev er al EWS stage wins, three EWS podi ums, one Swedish Nation al Enduro Cham pi onship, and they have only had one flat on race day.
