Hey all, so I'm thinking about getting an entry-level road bike to get my gf out on a bike and it's between the reno and etape. She has never had a road bike, has a 7300 now, and will probably not notice too much difference. Componets aside, is it worth an extra $90 for the Reno with the 6066 aluminum other than the 6061 aluminum? And what is the difference? Thanks.
