Ride what makes you smile. I’ve done the two bike thing but I always, always, always default to my hardtail. I don’t know why the biff I persist with FS bikes, I really don’t. Actually, I do. It’s reading magazines and marketing gumpf watching sick edits, man, that makes me think, “Hmm, that looks like a good idea” when in reality (for me) it’s not, it’s just more **** on with expensive stuff that I can do without.
Back to one bike, a BFe 275, with a few sets of 26″ wheels set up with different tyres and adjustable (120-160) forks. It does everything I need and want it to. It’s getting close to having singlespeed gubbins stuck on it, now the trails round here are a soggy mess.
edit- using the Rocket over the BFe for a while made me soft and lazy. It’s surprising how quickly bad habits (sitting like a sack of spuds, twiddling) form!
