I've owned my Jamis Aurora awhile and while I like the fit - I hate the Brifters. The component group Shimano Tiagra with a Deore rear deraileur has never worked right. I've adjusted it myself (within my limited and dangerous knowledge base) and taken it to my LBS and had it adjusted multiple times. Cable-slack removed, etc. It never shifts well. I much prefer the simplicity of my 520's uncomplicated bar-ends (which knock on wood runs like clockwork) and LX component group. I've considered (seriously) either converting the Aurora to bar-ends or trading it in (gasp) at the end of this year-ish for a Surly Long Haul Trucker. Off-Topic: would converting it to bar-end shifters be expensive? also, if I upgraded to LX components I bet that it would make it almost the same price all-together as the SurlyLHT.
Anyhow, those are my personal random musings. At one of the LBS, their guy told me that Surly is one of the few manufacturers that doesn't cheap out on components. He said the rest of them were very guilty of this. (they carried Trek, Felt, Giant, Surly, Redline, and others) Please, don't get upset - these are merely opinions and shared information for others benefit. I do like my Aurora alright.
