Thanks for the replies, plenty of food for thought – I think I’ll pop to one of the concept stores and have a chat with them.
I had just assumed that the Diverge range was all 1×11 setup so good to know they do offer 2×11 as well and that you can change from 1×11 to 2×11 if needed.
Ideally I’d have a gravel & a road bike but I don’t have space for both of them but I hadn’t really considered the Roubaix – what’s the max tyre size they can take?
