Thanks for posting this stuff. I am very used to the wide bars on the Sirrus Carbon now and like it. I use to have a Trek 7.5 FX with narrow bars and did not like it much. For the tires I put 23mm on and really enjoy it over 25mm, I have no brand preference really as long as they are cheap, can't go wrong with any big name brand of tire- I use the Vittoria brand.
