Who made these (Very similar to a well known BMX brand)?
Ti cranks, alloy spider. Made by a now defunct workshop in California called CQP, Cook's Quality Products, no relation to Cook Bros. The axle is also Ti, and the bearings are 72mm apart (outside to outside), compared with about 50mm on a normal internal cartridge BB. About 500g for the cranks and BB, <650g including spider and 49t 3/32 TA ring.
