I’m sorry but I bought the frame set on here for £260, ultegra so group £300 is fair, Columbus for is brand new basically £130, wheels surely fetch £80 with the rubber
This totals £770.
the finishing kit is lovely and tailored towards the bike £90,
What you paid for the finishing kit has no bearing on what it is now worth.
bar tape, saddle and full strip, degrease and rebuild, surely worth another £80, yeah pedals £30
It's a saddle and bar tape worth a few pounds.
The majority of people on the forum can strip a bike and put it back together and you cannot factor this into the bike value.
