Here for rides.
And if you had swapped from a 58cm Allez to a 56cm Allez?I used to ride a 58cm Allez and swapped to a 56cm Focus Izalco, I liked the look of the larger bike but the comfort of the new position is night and day - lovely.
Likely a lot more to the change you've experienced than the simple change in size.
