Specialized Roubaix sizing

Brocade

Folks,
Which frame is recommended for a 175cm/78kg rider on the Specialized Roubaix ?
Thanks in advance.

I'm about the same size and weight and I'd opt for the 54cm frame. However, it is best to try each size either side of that to be sure. You'll probably find the 52cm too small but the 56cm may surprise you. Pop into your LBS and ask them for at least a sit on (if they have it in stock) and better still a test ride.

That woudl be a 54cm. I am 180cm and ride a 56cm and could have could have gone down a size, but I do like being a bit more stretched out.

i'm same height and about a kilo lighter - I have a size 54 - an s-works one - love it!

you 'might' find a 52 fits but I think the reach would be too small and headtube so short that it would negate the riding position benefit of the roubaix - the 56 might fit too but the other problem - I would say that unless you have a weird proportio - i.e. really long / short arms or legs then the 54 will be ideal.

you can still set it up with the spacers to be really quite tall in the headtube - or quite racy and not actually far off the latest tarmacs (close to the allez) - here is mine setup for me so you can see what sort of post is showing:
(i have since lowered the stem by 5mm and cut the steerer tube flush as I have settled on the bar height.)

Many thanks all.
