I’ve recently tried this. I advertised my SS for a good price for a week or two and got a couple of offers that I declined (£400-£450) one taker, who said he’d pay but never did. He seemed very keen then just never coughed up by the agreed date. That was for £500 posted….and I hate being messed around…..
So in a fit of rage I stripped it down and banged one ad in the classifides. So far I’ve made £470+ taking postage into account and I still have the crankset, brakes, bars, grips and pedals left. So I’m already up on the deal as at £500 I’d have paid £30 to post the bike
I’ve decided to keep the brakes and cranks as the brakes are really good (Magura Louise) and the cranks not worth much, so better kept as spares.
So you’ll get more money if you split it, and it sells faster and easier.
