The day i have a $10k + bike is the day i'm a MAMIL
but probably by then, i'll have the legs to drop kids in their early 20's to justify something uber blingy like a dogma
[edit]
I do dream nightly about upgrading to the next groupset... but really, i dont see myself wanting to upgrade to ultegra... or even dura-ace. I don't see the moderate gains affecting my ride very much. my 105 shifts amazing already... i've already felt what ultegra is like. and i've shifted di2 before and it's ridiculous.
I'd opt for something di2
