It's time for my n+1. I want a lightweight roadie for commuting/touring. Liking the look of the Giant/Liv Avail, the disc brakes are a huge plus. Not sure about aluminum vs carbon. Pros & cons? Want a great entry-level roadie. My price point is less than 2k. Thoughts & suggestions welcome. Of course I'm going to test ride a bunch first, but appreciate the collective wisdom of TE ladies.
