Yes seriously. Your responses to my posts are littered with them, as I have pointed out many times. This might help:
https://yourlogicalfallacyis.com/ The 'strawman' is particularly relevant in your case.
Presumably you can't disagree with either statement then. Both points are on topic, so no need to 'hijack' the thread to answer them. Do try harder to understand what I've said before responding next time though, as most of our exchanges seem to come from you 'not getting it'.
I totally comprehend everything you are saying, that's not the issue. I just find it amusing that you always say things are pointless. I start reading a thread waiting for you to chime in and say it's not worth the spend. Have not misrepresented you either, so the straw man dig doesn't work sorry. Can't misrepresent when actually quoting words from someone else's post. Surely you comprehend that.
As to your arguments:
1.105 is not only lighter than Ultegra, so that argument is only part of it. It shifts better, is stiffer and is arguably better made and should therefore last longer. 300 grams of weight saving is also hardly sniffed at in my opinion, as it is with many others.
2. This bit is ludicrous. Anything looks like anything else from a distance!
As far as the trade off in the op's question, I think the Cervelo is the better buy than the Cannondale for the frame alone and its style. The groupset being the trade off for the frame.
Or would you suggest something from Argos based on the groupset weight being insignificant and them all looking the same from a distance?
