Bought my 26″ Five in September 2013, but can’t think of any reason to change it (and I’ve tried 🙂 ). I’ve ridden the (Mk1) 650B version and it just felt like a slightly heavier, slightly less fun version of the 26″ bike. Not bad, but no better. I’ve just put Pikes on so the suspension is bang up to date. Geometry is still a la mode. Short stem, wide bars. What else is there that I might want?
Some will say there are better bikes out there, but that was true when it was new.
I’ve got a Solaris, which isn’t being ridden much and may change that to a full suss 29er, but can’t see the 26″ Five going anywhere. To echo Northwind’s point, it’s a design classic and sits nicely in the Made in Britain corner of the shed, next to the Brompton.
