Unloved GRR? Not really. The GRR has met all my needs and "desires" thus far but I just recently got an itch for something different. No idea what really started the itch, but it's there.
Test miles on a Strada - about 50. ~7 on a Large (wrong, wrong, wrong size and I could definitely tell by mile 2). The rest on a Medium (much better, more comfortable). Been "offered" a trade for/sale of a Giro ATT - problem is I'm a Clyde so the ATT won't work for me, which also eliminates consideration of a Corsa. Never ridden a Giro, or a Corsa.
N+1? Nope.. N = N... like I said, I'll sell the GRR if I decide to go with the Strada. No room to store more than 1 bike. No desire to have more than 1.
And yes, Peter_C, getting a new bike WILL require selling the one I have.. along with many of the accessories (GT-54s and the Strada don't seem to be made for each other, for example).
