Had a look at the website and, with current exchange rates, it comes in at about £215. I'm not sure if it's worth that sort of outlay.
Anyway, I think I may have come to a decision.
Im going to buy myself a decent second hand road bike for the commute and blasting about at weekends, then use my beloved 90's MTB as the base for a "build your own tourer" project (my girlfriend's going to be so pleased!).
You guys and guyesses are so going to regret suggesting this, prepare to be inundated with daft questions on a regular basis!
Wish me luck!
I'm back with an alternative....;-)
You've said you don't want to touch your bike.... so don't!
You already commute on a MTB, so keep doing that, on your own bike.
Instead pick up a second MTB, as close as possible in spec to your own. And kit that one out for your touring.
That way, you save on spares, any mechanical knowledge you gain is directly transferable to your original bike, and when you go to cycle to work some morning and discover you've a flat, you just grab the wheel from the other bike.
Worst case scenario and you make a total mess of it, you'll still have your original bike intact.
And if further down the road you decide that you do want to tour on your original bike, the racks etc. will transfer over easily.
