Hi mate I don’t see a prob with asking this kind of question, if nothing else it will stop the classifieds getting clogged up with people trying to sell used goods for more than you can buy them new with a bit of searching.
Anyway I’m no expert but do buy and sell a fair bit through the classifieds, I’ll assume everything is in good condition, please bear in mind these are only my opinions and could fetch more or less.
Orange p7 frame single speed only £90-130
Xt cranks £65
Rock shox revalations 130-150 depending on age and travel
Chris king head set £40
Avid juicy elixirs which model a set of r’s about £90
Hope pro 2 hubs/ forgotten what rims £100
Thomson, stem, seat post seat post clamp £60 for the 3
Renthal chain wheel/surly rear cog peanuts
Hope that’s of some help
