Size: 19" Virtual / 18" Actual (a.k.a. "Large")
Tapered E2 Headtube, stock headset installed
12x142 Rear Thru-Axle, included

Used by previous owner for a few months. I bought it, rode it for 30 miles and decided I'd rather move the parts to a full suspension build. No dents or dings, only some worn paint from cable rub and dirt.
I can include the installed SRAM X1 crankset w/ 32t X-sync chainring for an additional $75.
