Help me decide. Roubaix disc or Diverge?

cntcasey

I am looking to buy my first real road bike in 2015. I currently ride a Specialized Secture sport disc with Sora components, but want to up grade this year.

I am confused on a few things?

These are the two bikes I have my eye on

And this one

If a person rode 50 miles on pavement on a 2015 Roubaix SL4 Comp Disc with road tires and then took those exact same road tires and put them on a Diverge Comp Carbon and then rode 50 miles. What would be the difference? What would a person come away from those rides saying?

If a person Rode 50 miles on a gravel road on a 2015 Roubaix SL4 Comp Disc with Gravel grinder tires and then took those exact same gravel grinder tires and put them on a Diverge Comp Carbon and then Rode 50 miles. What would be the difference? What would a person come away from those rides saying?

is this a riddle ?

I think they'd come back saying "I'm sorry for riding on the pavement officer", closely followed by "I wish I'd looked at some bikes apart from Specialized"

I have a non disc Roubaix and have recently ordered a Diverge which will be my winter bike.

So far as I can tell the geometry is almost identical. Certainly not different in a way that I thought it would make any impact to me whatsoever. The odd few mm here or there, but I can't see how I could feel that.

The significant difference is what tyre sizes you can use. The Roubaix takes 28mm max and the Diverge takes 35mm max.

On the same tyres the bikes will feel exactly the same.

So, make your choice based on what surfaces you want to ride. If it's just for the road then get a Roubaix.

And don't listen to anyone that moans about Specialized. The Roubaix is superb.
