1) I'm looking for a 36T 4 bolt middle ring / singlespeed chain ring to convert my hardtail to singlespeed for flat commuting. I was going to go 42/14, but I'd prefer to run 36/12 so I can use the middle ring position. Cheap, reasonable condition bits considered!
2) I'm also looking for a 12T cog. I know I can get a 12T cog for a couple of quid on ebay, so looking for as cheap as possible please!
Can pay by paypal.
