XTR 2015 + X1 = OK

scusate per la bassa qualità del video

cassetta posteriore XTR 11V su mozzo Soul Kozak , catena 10v , cambio Sram X01 11V , funziona tutto perfetto

sorry for bay quality of video footage, we were in a garage with neon light

XTR 11-40 11 speeds cassette with a X1 11 speeds rear derailleur and X01 shifters and 10 speeds chain, it works flawless
