I currently ride a mtb with slicks. I'm shopping for my first road bike in 20+ years. Was hoping to do something nicer, however, a ton of stuff has made it wiser to buy a used bike now and upgrade in a couple of years. Was looking at a 2007 Allez with a triple (tiagra shifters/front and 105 rear) and it just got me thinking.
