64CM Specialized Roubaix Comp availability?

Hi all,

I'm after a new endurance road bike, but my options are a little bit limited as I need a 64CM frame size. I've researched and researched and decided that a Specialized Roubaix Comp would be perfect for (I've had previously Specialized mountain bikes and like the brand, plus they are one of the few big brands who make an appealing road bike in this size/price range with this kind of stack and reach).

I know now is a particularly strange time and it's hard to find bikes in general, but it seems like this bike is not available in 64CM anywhere in the UK. Not on the Specialized website and none of the bike stores I have spoken with have them. To be honest in the past whenever I have bought a MTB or road bike I'm never able to test before buying, as in my experience bike shops never keep the largest sizes in-stock (which is entirely understandable).

I'm just wondering what to expect with regard to getting hold of a 2020 Roubaix Comp in 64CM. I know it was only refreshed this year, so I assume it might be a while before they are updated again? Does anybody happen to know if at this point in time Specialized are likely to produce more bikes in this range? I'm trying to work out if I just need to be patient and wait for more to arrive, or change directions and go with another bike. One store has suggested a Diverge might be a good alternative and made a compelling case, which looks great but I would prefer the Roubaix if I can get one as I already have a good MTB and really don't feel that I need the gravel part of a gravel bike offering. The MTB I have is for the trails and I want this bike for the road.

I have seen the bike available from a European bike store I have never heard of without a presence on Trustpilot etc, so I'm somewhat reluctant to go that route as it really doesn't inspire confidence.

Any thoughts would be very much appreciated. Also if anyone happens to know of a 64CM Roubaix Comp available from a reputable bike dealer then I'd be eternally grateful.
