Fair point @SirDAN and one of the things I’m mulling over. I switch to a winter bike usually around mid October depending on the weather in the UK. However, I do have a nice cycling trip in Spain in September which would be nice on the new bike (lots of climbing etc). Also, I have a slight concern that Cervelo will continue to have issues and that this rolls into a delay next year. That seems unlikely but you never know. So, as there is probably not a lot of difference in the bikes, it might make sense to take the bike you can get right now!
