Large cylindrical triple-GEM detector (CGEM) is proposed to upgrade the CMD-3 tracker subsystem. CGEM is considered both for precise measurement of z-coordinate of tracks in drift chamber (DC) and for generating signals for the first level trigger. This chamber will have better spatial resolution, trigger segmentation and rate capability with respect to the previous Z- chamber which is used in CMD-3 today. A new end-cup discs with GEM-based detectors are considered too. This tracker will improve significantly the detection efficiency for multi-hadron events, will help to study processes with ISR and measure the cross section with double tagged electrons when two virtual photons radiated by initial electrons produced C-even states (π⁰, η).
