A 20.75" Tri-Moly frame and Hi-Ten fork set the foundation for the L80. We built the rest out with a semi-integrated headset, an integrated saddle, tubular cromo cranks and an 8-spline mid-sealed bearing BB along with under mounted rear alloy U-brake keeping it out of the way and safe from destruction.
