Yeah it does. I asked about upgrading the cassete and what I guess he didn't want to talk about it said "I got some for 600 bucks" I guess he was going off if I look like I can't afford 600 bucks that's shut me up and it did.. But I'm doing al I can to learn I'm watching YouTube vids and learning about different bikes and all soon I hope to be a competent amateur mechanic with the forum it helps point me in the right direction.
