Umezawa NJS

got this for dirt cheap second hand. 2 dents on the top tube (who cares). Fully made of KASEI 8630R tubing, allowing this frame to reach an insanely lightweight 2.2kg which id consider is super impressive for an NJS frame. For reference my Panasonic fp28 weighed in at 2.9kg. Geometry wise i was really intrigued looking at the original listing, and i could tell already the geometry was something interesting. After receiving it and building it up, i was really satisfied and pleasantly suprised with the geometry, id say its around 74.5/75 fork rake around 30 ish, feels twitchy while riding. bb drop looks somewhere around 60mm unfortunately typical for an njs frame made for banked racing. Small amount of toe overlap, doesnt really bother me tbh. Stiffness wise not impressive actually, its meh.
