So as some of you might know I just recently got into mtn biking. I went 5 days out of the last since since buying my bike.
As I get more confident and aggressive the last couple days my chain has started to jump off. The three times it was after the smallest of airs.
It is a Haro V1. 21 spd, 3 gears.(7 per)
I am also noticing some issues when shifting from 6 to 7 or 7 down to 6 in 2nd gear. It seems to not like that change and sometimes bucks for a while.
What might be wrong?
Is this something a "tune-up" fro ma local bike shop address? Or something I can fix on my own?
TIA guys and gals!!
