I assumed he meant paying for Dura Ace over 105 when everything else isn’t of the same league.
it’s a bargain as a headline, it’s their sportif/comfort frame made out of their mid range carbon with a top end groupset on it, and not particularly inspiring kit.
Other than the “ooh bargain discount” or “ooh dura ace my precious” what do you like about the bike and what else can you get for the price?

“ghetto” (but actually terrific) 105 5800, a racier frame from a more boutique brand and has received huge acclaim.

or the more expensive 2015 colour scheme

gets you a quality frame (racier than the Solace) made from their ‘second tier’ carbon (like the Solace), with a range-topping groupset (like the Solace), nicer wheels and up to £330 change from your £2k.
Nothing against the Solace but it doesn’t inspire me and advising don’t be dazzled by the discount.
