At the LBS the Sirrus Pro complete with a full set of reflectors weighed 21.6 pounds. Not exactly lightweight but alot better than my 32 pound MTB. I've not had any problems with the front derailler although I have thought of putting an Ultegra on it to match the rear. The rear is jumping around occassionally but I'm waiting to put 150 miles on it before getting it adjusted.

It really does get better every time I ride it. The only problem now is that I've gotten good at doing full lock rear brake slides for entertainment so my rear tire life will probably not be great. Self control? I'm having too much fun.
