I am looking at the 2009 Scott Speedster S40 and the 2010 Specialized Allez Sport. The Scott would need to be ordered online. I test rode the Specialized and it seems pretty comfortable but has slightly lower quality components from what I can tell. I have had two back surgeries so comfort is my main issue. I will ride only for excercise and maybe a one day charity ride occasionally if I can get back into shape without back issues. Any opinions on either. The Scott is about $50 cheaper but I cannot test ride. Thanks.
