The Fiend Mills Frame was designed by team rider Lewis Mills. Constructed from heat-treated 4130 chromoly with an external gusset in the top tube and down tube. The frame’s tubing is double butted with a heat-treated Mid BB shell and head tube, externally butted seat tube with integrated post clamp and 8mm thick dropouts with integrated chain tensioners. The frame has a 5" tall headtube drilled for gyro tabs, and flush mount brake lugs on the tapered seat stays (sold separately)
