I bought a ss to cover commuting and off-roading for a while, as my commuter frame broke and the forks packed up on my hardtail at the same time.
A year later I still haven't bothered to fix my hardtail, as I'm enjoying ssing more now. It's ideal for forestry riding (Cannock, Wyre Forest, FOD, ) which make up the vast majority of my cycling.
I'd still want gears and front sus for trips to the Peak / Lakes etc, but I haven't been travelling to ride much of late.
