So I was riding home tonight from work . Downshifted for some lights and noticed a little more movement than normal in the gear lever...well actually it was terminal slop . So I thought " I know what that will be,, that will be the roll pin thats holds my gear lever on its splinless shaft throwing a 7 " . So I pulled over got the spare out my bag and smacked it in with the Gerber multitool . So I am thinking its maybe time it was changed ,its a bit boring ..but apart from the obvious shaft,seals,new pedal.. what else has possibly mined the minerals in that department ?.
