I'm selling my bike for 650 and Ill have enough for this and Im getting a new sprocket for it but I wanted to know about the stem it's one of those alloy stock stems and 3 of my friends have had them 2 of them had free agent ones and my other one had a united rn2 and they slipped a shit ton so I just wanted to know if it was just them not tightening them or if it was the stem. If it is the stem then ill just get a animal remix stem for it and a United metro sprocket. has anyone rode that sprocket is it good?
