I lost the bolt in the assembly process - it's item "1-1" in your assembly directions. A small bolt with *** for the brake cable to pass through and subsequently be held against the caliper. Its on the rear wheel. it's for "spectre #23080 - bar code 28914 2****. Need nut and bolt (washer?). Need any more info? Let me know of cost and delivery time please. I am putting this together for my grandson....I am not "pissed" yet! Phil Hartweg User's recommendation: Interesting, be patient.
