Wow - it's one of those Halfords £80 BSOs. I think it's safe to assume that it doesn't have a tapered steer tube (it'll be straight gaspipe ).

It really bugs me why they bother building these bikes with 'suspension' (which is absolutely *useless*) when they could use the money saved from building it hard-framed (no 'sus') and use it to spec better tubing and/or improvements in other components.
