I also have a Lux trail (previous generation). It’s a brilliant bike for what and where I ride. I live in the Lakes.
It is very much a quick XC bike – I’m 6ft and ride a medium. Reach is pretty much spot on for me. I don’t think I’ve ever used the lockout but it is reasonably rocky and rough up here so perhaps I would use it (the lockout) more elsewhere?
Like jonba, if it broke, I’d happily have another.
