It's a good idea, I suppose, if for example I purchased the saddle/seat post combo for £32.00, the actual cost of a new cross country saddle at the low end price range would be £30.00 say from Halfords and a new Suntour NCX is about £55-60 then it does work out at good value - Its a shame I didn't know about this when I purchased everything new, instead I purchased a cheap cable lock to pop through the Suntour and I never leave my bike for more than half hour max + buy this homeless guy a bacon butty once a month and he keeps an eye on it if hes about.
