MountainBikes II frame-set (head tube is not machined) parts/fork determine model Unsure what the first digit means (Example: 3A946) ' faux lugs' at the head tube and seat tube more relaxed angles than other models offered at time Later frames (late '90s) tend to have a better model designation: SC = Swiss Cross, NT = NiTi, RL = Road Logic, etc.īelow is a guide to (mostly) US-made frames showing information about each model.Ĭontinuation of the Everest which had previously been had an 'R' serial number sculpted seat tube reinforcement (also used on later Team Comp model) Additionally some models (particularly older frames) fit neither scheme.
