Aeroad spec is hard to beat for the price but from what I last saw the bikes were out of stock until Feb.
Is the front wheel on the Canyon 60mm? I remember the AR58s on the old Aeroad were tough for me to ride with (65 kg).
Either will be fabulous. I’d suspect the Canyon will be marginally faster in most conditions, but I wonder if the Specialized might be a bit more fun.
I might also look at the Scott Foil. A mate has just got hold of one and is raving about it.
