can't remember if i've already said this, but--the vast majority of the riding that i do, and plan on continuing to do, is not touring. i need a bike that is capable of light touring, but i'm not buying a bike to tour. the comp appeals to me (although not the pricetag--i'm looking for any of these bikes used) because of the 105 and ultegra. i know opinions on this vary greatly on this forum but given my experience working at a shop and the number of miles i put onto my bikes, i just don't think tiagra is a great option. in my experience, tiagra and sora require so much tinkering (at least once you get to a certain mileage / level of riding) that it's worth it to bump up to 105 in the first place. but, as i've said, i don't have an unlimited budget, so i'm keeping my options open. and $2050 for an ultegra-equipped bike (and not even full ultegra!) is, in my opinion, pretty absurd.
