First of all, I am super impressed with your riding endurance. You are AMAZING!
Second, as far as I know, the Specialized bike company gives a lifetime guarantee on their frames for the original owner. So, if your frame cracks, the store will either fix it or replace it for free.
The Amira does feel different than the Ruby to me in terms of the top tube length. I personally cannot feel the smoother ride quality of the Ruby with their Zertz inserts.
Hopefully, Orbea will fix the frame for you for free. I thought that the Orbea Gold was supposed to be fantastic.
