I think the upgrade pricing is maybe different in the UK then. When I specced mine how I wanted it the price actually dropped 🙂
I tested the second up model and loved it. I had a proper day of techy and fast stuff on it, riding with some of the fastest guys around, and pretty much felt comfortable on the bike straight away. I have to sort a few things out to see if I can afford to buy one, if I do it´ll be the BOS one despite the fact that the TALAS 34´s were pretty nice. I´d like to go 1×11 on it too, but that´s only an option in Spain on the very top model which comes with carbon wheels etc.
I don´t know about delivery. For me it´s usually just a case of driving to the factory, having a coffee with the guys and heading back with a bike!
