it's an Alex R500, 10 spoke radial laced w/ large amount of bondo, drywall, chicken wire & paper mache wrapped around each pair of spokes to give it lateral stiffness and perpendicular rigidity while making it horizontally compliant and vertically smooth. Sanded, shaped & handpainted by the boys at Montano Velo with paint pens in a limited edition of 6. Better get on the stick if you want to pick one up OP,
