Bicycle wheel at perpendicular to the axle and go straight to the rim, without crossing any other spokes - e.g., "cross-0". This lacing pattern can not transfer torque as efficiently as tangential lacing. Thus it is generally preferred to build a crossed-spoke wheel where torque forces, whether driving or braking, issue from the hub. Where braking is concerned, the older-style caliper devices that contact the rims to apply braking force are not affected by lacing patterns in this way because braking forces are transferred from the calipers directly to the rim, then to the tires and then to the roadway.

Are Years What? (for Marianne Moore) mobile with wire, shaped like a "V". "Are Years What? (for Marianne Moore)" is signature of di Suvero's monumental early 1960s "open-work constructions." These works utilize cast-off construction materials like chains, metal bars, and ladders. This sculpture is the first that di Suvero built, from beginning to end, with I-beams and using a crane, solely by himself. "Are Years What?" was originally in the collection of the artist, then the collection of Enrico Martignoni of Winnemucca, Nevada. Hirshhorn director James Demetrion first saw the sculpture when it was on display in Brooklyn's Prospect Park. The sculpture was acquired by the
