One of The last year of Nicolai`s 26" Era!..

Before the now prevailing notorious Geolution Geometry as what Nicolai calls it,
It was usually common on Team frames and so always some customers chose it on custom frames or for upcharge to have a low toptube with a bonus of standover clearance.

This one in stealth black elox, S Seattube, M Toptube
"Später AC Hauptrahmen mit AM Dämpferaufnahme und Oberrohr"
Geo changes on the late 26" AC made this model very similar to the early 1st year Helius AM (see Nicolai tech manual for Shock rocker upgrade types), despite maybe a low BB.

The frame was prepared inhouse for Truvativ HammerSchmidt planetary drive, here we have the lighter brother build
