Good eyes seeing the cassette in this view!
Anyway, on the lookout for an upgrade. Might have to wait till next month now though. Funds areee low after spending so much on my two modern bikes.
Ill have to keep riding it like so for my commute,
Btw it's got a single speed kit by gusset on there at the moment, have been just leaving it on the big ring until I have money for gearing parts.
So in conclusion, yes it does need a cassette. Chain is looking well old too... U might be right?!?!?!
