Along with their wider bead wall, Ibis has added inner bracing close to the bead for the rear Ship II rim to forestall dented rims each time potential. The profile illustrations beneath present the distinction between the 2 rim designs, with and with out the added help. These braces are stated to extend rear rim weight by 45g.
The brand new Ibis Blackbird Ship wheels can be found in 27.5″ and 29″ diameters, weigh a reported 1939g and 2060g respectively, and both measurement retails for $529. Rims alone retail for $99. The units use Ibis branded hubs, with 4 pawls and 36 tooth for 10° of engagement. That’s a bit extra obtuse engagement than we’re seeing with most different hubs, however the majority of latest wheel manufacturers are utilizing Trade 9 hubs, the place engagement is a major promoting function.
