I ride Leith Hill/Holmbury every week on my 575 and I can’t really say I’ve ever felt “overbiked” Also ridden Swinley, Cwmcarn Downhill, Affan and Richmond Park cycle path with the wife. If I only rode my bike on the optimum trails I probably wouldn’t get out very much. I suppose if I could afford a DH bike (which I can’t) then I’d feel a bit “overbiked” popping down to the paper shop…..Then again.
