it's the next thing to go then wheels but it's gonna be a while before i spend more on it

 Black seat, white rims black spokes white hubs is planned, and then maybe blue nipps

 I do with my current rear cog, however my old one was fine. Gonna switch back when I can be bothered to play around with chain links

 I keep getting problems with mine. I have always had a 'clunk' which sounds like the chain trying to come off but 'snapping' back on due to the tension.

My old chainring got ovalised but that was on an old setup blah blah blah.

My new setup (new velosolo ring, new shimano dx cog and new ybn chain) all last month, the chain ring or cog is ovalised already! Chain is near to tight, then really slack when spinning the pedals.

Im not sure what to do :'(

 The rear sprocket I'm going to put back on has insane teeth, like they poke out between the links insane. I used to be be able to run my chain at stupid levels of slack and it came off less than it does now

 What sprocket was it?

 Apparently an onza single speed specific one

 Hmm may look for one of those!

 One of these?

Is yours not just the same as my shimano dx?

 Literally haven't got a clue

 What the one we had to use when we built shred up or my old one?

 Your old one didnt i give it you? The one now is just one from a cassete

 I swapped it for Connors single speed kit when he decided he was going geared
