My boss has a slightly older Allez which he has stuck an Ultegra groupset and deep section Mavic wheels on. It looks awesome, for some reason the description that keeps springing to mind is ‘street fighter’, probably because it’s a 52 and matt black and aluminium, kind of gives off a bit of a bombproof but nimble look.
His weighs 8kg apparently, and the new frames/forks are reportedly 0.45kg lighter than old. I’m certainly considering one with upgraded wheels, brakes and tyres, reckon I could get it down to 8.3kg-ish with the stock 105 groupset and stock alloy bars, stem and seatpost.
